Introduction

CAREFULLY READ THE ENTIRE MANUAL BEFORE INSTALLING

n InfraRed (IR) link allows connection without any cable between two distant sites. For that, two identical transceivers, each installed on one site and aligned to face each other, provide point-to-point connectivity. This

configuration makes possible data transfer from one terminal to the other through the air over an optical wavelength carrier, the IR link – see picture in Figure B, below.

Figure B: IR Link

The installation of such a link can be summarized as 4 stages:

♦

Site survey

♦

Installation of the infrastructure

♦

Mounting of the equipment

♦

Aiming (alignment) procedure

Always use appropriate safety equipment and procedures when working with electrical equipment and when working on roofs

C. TS800/155-F (Standard Model including Fusion option)

This special TS800/155-F model can be connected to the back-up radio system without a special MRV switch and card supporting Fusion. This TereScope can be connected to any switch (supporting 10/100 Mbps data rate) via a standard converter that should be connected to the optical port of the TereScope labeled “Redundant”, while the back-up radio system is connected to the same Switch.

As an alternative, the TereScope can be directly connected to a Media Converter of type 10/100 TX-100 FX (for example, MRV’s media converter MC102F). When the TereScope stops operating, the connectivity from the main optical module to the air channel stops and starts flowing into the second optical module designated for radio.

Fusion Operation Mode

When at least one of the air channels (IR) is cut for more than one second or drops to approximately 60 mV at the display readout:

1. TereScope switches to Fusion mode

2. Data is transmitted from Main module to Redundant module without passing through the air channel

3. The signal is converted to 10Base-T by the Switch and the data Rate decreases to 2-10 Mbps

The system switches back to IR channel (TereScope) only when the display readout on both sides increases to approximately 150 mV.

Note: To activate the Fusion option, set DIP Switch toggle 5 to the ON position.

The TereScope Fusion was designed to combine the best features of two transport mediums, laser light and radio waves, to form a single, seamless, wireless communication link between network devices. By leveraging both technologies, we can provide the 99.999% availability that your network requires.

The TereScope Fusion has been specifically constructed to maximize link availability between network nodes. These systems use the internationally unlicensed, 2.4 GHz ISM band and are used as a backup for a number of TereScope systems.

TereScope Fusion systems have an optical wireless link that provides Fast Ethernet connectivity as the primary link and Ethernet RF as the backup link. These systems operate in most weather conditions, including heavy rain, snow, and fog with nearly 100% link availability. Ease of installation and freedom from licensing make these systems very simple to deploy.

Site Survey

The first step before every installation is to visit the sites to be linked. in order to make sure that the connection is feasible, to find out potential obstacles or difficulties and to decide on the location and mounting points of the transceivers.

Line of Sight

A necessary condition for linking two distant buildings is that the two mounting sites must be within clear sight of each other.

Pay attention to:

Growing vegetation and increasing foliage during spring

Building sites (cranes movements, etc.)

Chimneys (intervening smoke can interrupt the beam from time to time).

Orientation

Direct sunlight can overload the airlink receiver to saturation level. Avoid, as far as possible, the East-West direction for the link.

Note

In case this is not possible, the surrounding buildings could shield the transceiver from the direct sunlight otherwise outages lasting several minutes (depending on the time of the year and the angle of the sun) could occur. The system will fully recover once the sun is out of the receiver field-of-view.

Location & Range

1. The mounting of the transceiver must be very rigid (preventing the installation from twists of even as little as 1 mrad). The key to the required rigidity is to attach the mounting accessories on strong mounting points such as:

- Stiff building structures

- Concrete or reinforced concrete surfaces

Chapter

Page 28

MRV Communications, Inc. – Installation Manual

Prefer Avoid Pay attention to

Concrete Parapet Structural wall or column

Old constructions Soft material (asphalt, etc.) Non-uniform surfaces Wooden and metal structures

Colored windows Double glazing The proximity of powe

radio antennas

For reasons of convenience, it is always preferable to install the units indoors as long as all the required conditions previously described are met and the customer/building owner allows it. However, when windows are present in the beam path, the attenuating factor of the glass must be considered regarding the distance and the required fade margin.

2. Referring to the data in Appendix A: Product Specifications, set and record the distance between the two TereScopes of the link. (You can use any of the following equipment to determine the distance: rangefinder laser binoculars, GPS receiver, maps, etc.)

3. Noting that two TereScope units are required per link, record the quantity of each model of the TereScope required.

4. Record the bearing to the opposite site by compass.

5. Record the number of links to be installed at the site.

6. Note whether additional sheltering is needed for the TereScope, for e.g., against strong winds (120km/h or more)

CONSULT FACTORY IN CASE OF DOUBT !

Figure 2.1 and Figure 2.2 show optimal and acceptable locations for the TereScope links. Notice that in both figures the TereScopes are mounted on rooftop edges and high enough above the ground.

(1)

In case such situations cannot be avoided, special mounting accessories and techniques must be designed and considered (see section Particular Figure Cases\Techniques page 37)

TereScope mounted at corner of leading edge of structure.

Figure 2.3 shows an unrecommended TereScope link location because of interference by IR. Notice that the TereScopes are mounted far from the rooftop edges or are too close to the ground.

Figure 2.3: Unrecommended Mounting

TereScope not at edge of roof.

Beam path p asses too close to ground. Heat rising causes scintillation. Allow 4.5 m (15 ft) between ground and beam path.

Less than 4.5 m (15 ft) between beam path and heat-emitting surface.

Beam path more than

4.5 m (15 ft) above surface to avoid traffic and rising heat.

TereScope at edge of roof so that heat rising from roof surface does not affect beam

Page 30

MRV Communications, Inc. – Installation Manual

Figure 2.4 shows an unacceptable TereScope link location because of interference by passing vehicles. Notice that the TereScopes are mounted far from the rooftop edges and not high enough above the ground.

Figure 2.4: Unacceptable Mounting

Mounting Environment & Stability

1. When deciding the mounting location, you should look on the rooftop for vibration sources such as compressors, elevators, motors, and try to avoid them.

2. Photograph the mounting location so as to select the best mounting option. Figure 2.5 shows mounting locations on a rooftop in descending order of preference. Location 1 is the best; location 7 is the worst.

Figure 2.5: Mounting Locations in Order of Preference

Page 31

MRV Communications, Inc. – Installation Manual

Note:

If the only option to mount the TereScope is at points 5, 6 or 7, it has to be mounted at least 2 m above the rooftop to avoid roof scintillations and people crossing the link beam (If possible, avoid placing the TereScope on a mast).

3. Avoid surfaces with high reflectivity (e.g., white walls) behind the TereScope so as to reduce interference with the optical signal.

4. Get customer approval for the exact positions where the TereScopes will be mounted. Using paint, mark these positions.

5. Note the height that each TereScope will be above or aside the rooftop.

6. Identify the floor or wall type and dimensions of the location at which it is planned to mount the TereScope.

7. For each TereScope head, select one of the following mounting options2 and record it.

a. Parapet/Ledge Mounting (Figure 2.6) – This is

a standard mounting option that uses only the Plate (JMP).

b. Wall Mounting (Fig. 2.8) – This is a standard

mounting option that uses the Plate (JMP) as well as the two Brackets (JMB).

c. Floor Pedestal Mounting (Figure 2.7) – This is

a non-standard mounting option that uses the Plate (JMP) as well as a Floor Pedestal (e.g., M015C).

d. Wall Pedestal Mounting (Figure 2.9) – This is a

non-standard mounting option that uses the Plate (JMP) as well as a Wall Pedestal (e.g., M054C).

e. Extended Wall Mounting (Figure 2.10) – This is

a non-standard mounting option that uses the Plate (JMP) as well as an Extended Wall (e.g., M062C).

f. Angle Bracket Mounting (Figure 2.11) – This is

a non-standard mounting option that uses the Plate (JMP) as well as an Angle Br acket (e.g., M001).

Transmitting through a Window

1. Determine the number of surfaces the beam transits or is reflected from, the reflectivity of each surface, and condensation/precipitation collection areas.

2. Use the data below to determine whether the light beam attenuation is acceptable.

4% attenuation for each surface of light

reflection.

15% attenuation for a double pane window. Attenuation due to tint in windowpane must be

taken into consideration in choosing the right TereScope model. (The % attenuation depends on the tint and must be measured.)

3. Ensure that the angle of incidence3 of the beam striking the windowpane is between 1º and 45º.

Note

On high buildings, for indoor window installation, the user should consider that occasionally the window-cleaning elevator might block the link beam.

Angle which the light beam makes with the perpendicular to the windowpane

Infrastructure

The only infrastructure required for operating the transceiv er and linking the sites is Power and Data/Signal connection to the peripheral networking equipment. This must be ready prior to the airlink installation

IN OUTDOOR INSTALLATIONS, USE SHIELDED AND WEATHERPROOF MATERIALS (CABLES, INLETS, AND CONNECTORS) COMPLIANT TO THE SAFETY STANDARD IN FORCE.

Power

Source

The power requirement for standard units is 100-240VAC @

50/60Hz - 10W.

Note: Units requiring low Voltage: 24-60 VDC - 10W can be factory set upon request.

It is recommended to use a Surge Suppression System to avoid damage to the equipment when power supply is unstable. Protection should be at least 25,000A.

Cabling

Standard 3-conductor power cords are required. (See Safety

requirements, Page iv)

Data/Signal Cabling

1. For TS700/155 , TS700/G, TS800/155 , TS800/155-F

Type For connecting the Transceiver to the peripheral equipment, a dualfiber cable is required (one fiber for transmission, the other for reception). The standard recommended cable is MM 62.5/125 µm fiber or SM 9/125 µm for fiber.

Connectors Each fiber should be terminated with the ordered type of connector on the transceiver end (SC, ST).

Optical Fiber testing.

The cabling installer must specify the attenuation of each fiber installed.

Chapter

Page 35

MRV Communications, Inc. – Installation Manual

A simple power loss test can inform us about the condition of the fibers. This test consists in measuring (with an optical power meter) the output power at one end of the tested fiber when a fiber source is connected at the other end. If the values are in dBm, the difference between the input power and the output power gives the power attenuation of the fiber (in dB).

Optical Power Meter

Peripheral

Equipment

Optical Source

F/O

Fiber Optic

Cable

In case the above equipment is not available, a simple visual test may be performed to locate and reject badly damaged fibers. Place a light source at one end of the fiber and intermittently block it and observe the light coming out of the other end. (This procedure does not guarantee that a fiber is acceptable)

A standard 62.5µµµµm fiber optic cable is characterized by an attenuation factor of about 3 to 5 dB/km. A loss value of more than 3 dB for runs up to 200m indicates that the fiber may be faulty.

Note

The fiberoptic cables must be installed by a qualified person.

HANDLE THE FIBERS VERY CAREFULLY.

2. For TS700/100

Type For connecting the Transceiver to the peripheral equipment, 2-pair

STP Category 5 cable is required (one pair for transmission, the other for reception). This cable must be a straight one when the peripheral has an MDI-X 100Base-TX interf ace and a Cross one otherwise.

For PoE (Power over Ethernet), 2 more pairs ST P Category 5 cable are required. (Use only for the Low Voltage version: TS100/A/FET/V3)

Connectors The cable should be terminated with an RJ-45 connector at the Transceiver end.

The TereScope Head, Aiming Head, and JMP-L are shipped connected to one another. Before mounting, in order to make installation on the mounting surface easier, the JMP-L must first be detached and connected to the fixation surface. Next, the TereScope Head and Aiming Head can be mounted. To detach the JMP-L, screws ‘B’ should be loosened and screws ‘F1’ and ‘G1’ only should be removed. Do not remove the ‘G2’ screws !

If the TereScope head is to be detached (e.g., for servicing, but we recommend to send the entire unit TS + Aiming head to the manufactory), remove the four ‘G2’ and ‘F2’ screws (Fig 5.11).

Note

For more convenience it is suggested to assemble the 3 parts of the JMB before mounting it on the surface.

Special Mounting

1- Mounting on the floor

In some cases the only place where the installation is acceptable, possible, or authorized is on the floor. Avoid installation on roofs with a metallic parapet or without a parapet by drilling holes in the roof floor.

*These bolts and nuts are included in the kit

Figure 5.14: JMP-L on JMB

Page 47

MRV Communications, Inc. – Installation Manual

To use the floor, a very stable tower standing on the floor is required. The transceiver will be fixed on the top of the tower.

Two techniques using a small concrete block are suggested for stabilizing the tower on the floor.

• The concrete slab material is poured directly on the base of the tower

• Four bolts are inserted in the concrete slab placed on the floor. The tower

mount is fixed on the slab with the inserted bolts using nuts.

TAKE CARE TO REMOVE ANY INTE RVENING SOFT MATERIAL, SUCH AS ASPHALT, BETWEEN THE SLAB/TOWER BASE AND THE F LOOR. ONCE T HE INST ALL ATION IS COMPLETED, RESTORE THE ROOF WATER-TIGHTNESS WITH SEALING MATERIAL AROUND THE SLAB.

2- Mounting on a fragile/crumbly wall

On sites on which the installation on fragile (pre-fab) or crumbly (old building) walls is unavoidable, the best way to strongly fix the JMB is to use a metallic clamping plate on the other side of the wall as sketched below. In this technique a large section of the wall is clasped providing higher rigidity and stability.

3- Attachment of the Transceiver (TereScope Head)

After securely attaching JMP-L to the mounting surface choose one of the three possible directions for installation of the Alignment Kit (Standard A, B or C) depending on the location of the transceiver at the opposite side. Mount the aiming anchor (I) in accordance with the chosen direction.

Mount the Transceiver attached to the mounting bracket front face oriented towards the opposite site using the provided screws (F1, G1). Tighten firmly these screws.

Transceiver Alignment

General

Point-to-point connections require face-to-face orientation of both transceiving ends of the link. With wireless optical links, the beam spot should be positioned symmetrically on the remote receiver, as accurately as possible.

Successful installation of the TereScope depends primarily on precise and accurate optical alignment. Carefully follow the instructions below!!!

Tools and Equipment

Note

The customer can order patch cables and high-outpu t portable source from MRV.

The following tools and equipment are required at each link end:

• A communication device (mobile phone or walkie-talkie)

• Optical-power meter, giving readings in milliwatts/microwatts or

dBm. (The Optical power meter is convenient though not necessary.)

• JITK-L.

Procedure

Turn on the power to the TereScope heads from the power source. Models TS700/155 ,TS700/100 and TS800/155: Set DIP switch toggles 1, 2 to the “Alignment” position (indicated on the back panel). In TS800 models set the SD2 DIP switch. In TS700/100 only DIP switch toggle 1. Model TS700G: Even if the data port is left unconnected, the TereScope transmits an Idle Signal which can be used to perform alignment. The transceiver alignment procedure is implemented in two stages:

# Coarse Alignment # Fine Alignment

Coarse Alignment

1. Make sure that both axes (horizontal ‘G1’ and vertical ‘G2’) can

turn freely (but you should’nt loosen or open the ‘G2’ screws). Loosen bolts F1 and K at least two turns and G1 aiming axis loosen slightly. Loosen bolts D and bolts F2 on both sides of the transceiver.

B (x2)

Fig. 6.9: Telescope crosshair on the opposite TereScope

2. While looking (see fig 6.9 below) through the telescope, rotate and tilt the TereScope to bring the telescope crosshairs on the left side (your right side) of the opposite TereScope.

3. Tighten firmly 4 Bolts K and D in such a way that the aiming anchors (L1&L2) will be between the screws C and B.

Fine Alignment

The purpose of fine alignment is to position the center of the transmitted beam spot on the center of the TereScope receiver – in both directions (Fig

6.10). This is achieved by adjusting the horizontal and vertical motion screws (shown in Figure 6.11) until maximum power is received at the opposite TereScope.

Fine Alignment Vertical Motion Screws – Two screws (‘C’). Used for fine rotation of the TereScope in the vertical plane. Fine Alignment Horizontal Motion Screws – Two screws (‘B’). Used for fine rotation of the TereScope in the horizontal plane..

Note

# Two installers are required for fine alignment, one

at each TereScope site.

The installers should each have a walkie-talkie, a mobile phone or any other equipment to enable each to talk to the other working at the opposite site.

The fine alignment procedure is as follows:

1. Find the horizontal and vertical Beam edges (H1, H2, V1, V2) by obtaining a reading between 50 and 80 on the 7-segment display. (between 250 and 300 for the TS700/G)

2. Set successively the remote transceiver in the middle of the two segments [H1,H2] and [V1,V2].

H1 H2

Important: Do not in any case select the head position for which the DVM reading is maximum! The best position of alignment is the beam center.

To determine the horizontal beam edges H1 and H2, move the local transceiver slowly left and right until the digital readout on the remote transceiver becomes 50. (250 for the TS700/G) Identify these two points relative to reference points on the opposite site by looking through the telescope. By moving the local transceiver, set the remote transceiver at the middle of these two reference points.

H1 H2

Page 53

MRV Communications, Inc. – Installation Manual

Fig. 6.15a and 6.15b: Alignment screws

Repeat this process for the vertical positioning (middle of segment [V1,V2]).

Once the position is reached, tighten firmly the 4 Fine Locking Screws (2xF2, 2xF1 and G1).

Repeat this procedure interchanging roles with the second installer at the opposite site, i.e., the second installer will move the remote transceiver while the first installer will report the digital readout at his end).

After finishing the alignment process it’s possible to remove the alignment kit (2 Aiming Lugs E1, E2 and Bolts K and D and screws B and C).

At the end of the procedure, t he digital readout should be approxi mately the same on both transceivers (see Appendix B page 44 for expected readings).

Link Operating Test

Set back the Mode Select Dip-Switch on the Normal position (the Alignment indicator should switch OFF (if exists depending on the model)).

At both sites, connect with fiberoptic or STP cables coming from the peripheral equipment to the fiberoptic or copper port of the transceiver.

IT IS A CROSS CONNECTION:

TX $RX AND RX $ TX

The F/O RX Flag and Sync. (Electrical flag and Rx on TS700/100) indicators should turn ON as soon as the peripheral equipment is powered ON.

A BER test is recommended. In case this is not possible at least check with the customer/user the performance of the whole link (see the chapter Bench T est).

Installation Log

Write down all the information about the installation (including digital readout and the setup of the transceivers) in an installation log. This information is a valuable reference for future maintenance or troubleshooting visits.

An example of an installation form is shown in Appendix H.

Before Closing the Rear Door

1. Ensure that the Power Supply Cover is fastened in place.

2. All cables are properly held in position.

Visual Inspection

Visually check that all parts and cables are connected.

Closing the rear door

Rotate the Rear Door around the axis (I) and push it. Close the five screws H -

- see Figure 6.16., .

Installation Completion

Check that the heads appear as shown in the photographs below.

Maintenance

Periodic Visits

Periodic visits (every three/six months, depending on the installation environment) should be planned for:

• Checking the display

• Checking the mounting

• Cleaning the optical aperture of the transceivers

• Cleaning the building windows for indoors installations.

At cleaning time, the reading of the digital readout should be noted in a service log book. If after the optical aperture is cleaned the reading is substantially lower than that noted at installation time, the aiming accuracy should be examined and restored if necessary.

Note

Aiming accuracy should be checked looking through the telescope and comparing the present scene sighting to the one sketched in the Installation Log at installation time.

Actual reading may be greater or up to 15% lower. NOTE: with the Transmitter in “Attenuated” mode for distances under 150m

(DIP switch toggle 1 OFF), the DVM should show readings varying from 800 to 1150.

A note on the Digital Readout Charactersitics of the TS700/G

The digital readout of the TS700G works under a different principle from previous TereScopes in the series. The readout level is derived from the actual light level at the photodetector, much like a standard optical power meter. For this reason, background light entering the lens will also contribute to the reading. A typical reading with no signal on a sunny day would be 030 to 080. This will sum with the signal strength, so outside the reading at the minimum threshold would be higher than the reading for the corresponding signal in a bench test. Due to the AGC function, for higher signals the offset in the reading gradually becomes negligible. All this has no effect on the actual link performance. Please note, however, that the Air Rx LED is not affected by background light, and is purely a function of the received data level. So even with high background light reading, the Air Rx LED will not light in the absence of signal.

TereScopes Bench Test Procedure

Introduction

All TS Products are bench tested indoors prior to outdoor installation to ensure that the system is fully functional. The bench test is a simple procedure whereby a link pair is aligned on the table and activated to simulate a channel of communication (see fig.1).

2 Points to Remember

1. Since the link distance during the bench test is very short (i.e. the devices activated are very close), the receivers will go into saturation unless the signal is attenuated. (NOTE: In the 700/G, deep into

saturation the DVM reading may actually drop back down, giving the false impression that the link is misaligned. It is therefore vital to place the attenuator in the link path before optimizing alignment.)

To avert entering saturation, the transmit signal must be physically attenuated. We recommend the simple procedure of inserting a piece of paper or the like into the beam path, or concealing a portion of the beam with an opaque (non-transparent) material. This will reduce the signal power entering the receiver. Make sure to attenuate the signal enough so that the receiver’s optical power meter value falls below the saturation estimate of the device. See table below for saturation estimate.

2. An additional derivative of the short link distance is the presence of reflections. The signal will reflect off the front window of the receiver back at the transmitting device and may be mistaken as part of the opposite transmission. This interference is commonly called “cross talk”. To avoid cross talk during the bench test, it is advisable to check whether interfering reflections exist by shutting off power to one device and verifying that the optical power meter reading in the other (active) device is zero. This should be repeated for the opposite device. Alternatively, a practical setup for bench testing the 4” series (models B, C and D) and Light series (models A and C2) is presented in Figure 1; the bench test setup for the 10” series (models E and F) is presented in Figures 2a,2b. In the 4”/Light setup, a thin physical barrier, such as a piece of cardboard, is used as a wall to divide between the beam paths, thus ensuring that no cross talk occurs. In the 10” setup, the two devices are not centrally aligned; instead, only one corner of each device faces the opposite device. This

allows for testing each transmitter separately. By rotating the devices 45 degrees, the next pair of transmitters is tested. Hence, testing all 8 transmitters in the link pair requires only 4 rotations. In the 8” setup, the two devices are not centrally aligned; instead, only one corner of each device faces the opposite device. This allows for testing each transmitter separately. By rotating the devices 45 degrees, the next pair of transmitters is tested. Hence, testing all 6 transmitters in the link pair requires only 3 rotations. With opaque masking tape, cover all transmitters that are not under test.

Effect of Wind on Ter escopes

Introduction

The outdoor environment in which our devices are normally placed exposes the link to wind pressures that may affect the accuracy of the link’s alignment.

Several factors play a role in the determination of the extent to which the directionality of a TS device may be affected by the wind: Wind speed Wind direction Surface area of device perpendicular to wind Mechanical stability of aiming head – device system.

For example, the mechanical stability is greatest along the side-side axis of the device. Although the surface area along the side of the device is greatest, the resultant wind force – even at very high wind speeds – will barely have an impact on the beam’s direction, due to the rigid mechanics along the side-side axis.

Wind Limits for TS Devices

All TS devices have been tested in “worst-case” scenario of the above four factors. The force necessary to deviate beam was measured from different direction. From here1, the minimum wind speed with maximum effect on beam deviation was determined. The following table lists the minimum wind speeds for different TS products that may cause: A momentary lapse in the communication. An extended lapse requiring mechanical repair.

TS Device Momentary Extended

• 10” (E&F models)

• PAL (TS1)

180 km/hr Over 250 km/hr

• 8” (Models D2, E2, G)

150 km/hr

We include here the formula for calculating the effective wind force on a flat surface, given a known wind

speed:

Wind Force = 0.79 x (Wind Speed)2 x (Area of Surface)

For instance, assuming a wind speed of 27.78 m/s (equal to 100Km/hr) on a surface area of 0.04m2 (400cm2), the force is equal to 24.4 Newtons.

FSO Chaining

What is Chaining?

The Chaining of FSO is required when the two sites are connected by more than one link using at least one additional building as a mid-point.

When is the Chaining required?

The Chaining of FSO links is required in the following cases:

a) When there is no direct line of sight between the sites; b) When the distance between the sites is too long; c) When the distance between the sites is reachable with one link but the customer wants much

more Power Budget for higher reliability.

Fig G.1:

As there is no line of sight from A to B, we are using C as a repeater point. On C rooftop we used “ Direct Chaining connectivity

Indirect Chaining

Direct Chaining

Chaining Limits

The number of links that can be chained is limited due to the Jitter parameter. Sensitivity to jitter is different for every protocol and can vary with different manufacturers. The typical number is 3-4 chained links. If more chains are required, please consult your MRV representative.

Indirect Chaining is required for connecting FSO units not including clock recovery circuits. In cases of indirect connectivity, the connection between the two FSO units on the same roof must be done through the Switch or Router or another means of connection that is located inside the building. For example, in Fig. 2, we use the indoor switch in building C for the chaining.

Direct Chaining is the capability to directly connect two FSO units on the same roof (used as repeaters ) i.e.. direct crossing between Rx and TX of the two units. For example, in Fig. 3 connection is achieved on rooftop of building C without the need to enter the building.

Direct connection is possible for FSO that include clock recovery circuits. The clock recovery regenerates the signal and enables smooth direct chaining.

APPENDIX I

Power over Ethernet

The Power-over-Ethernet (PoE) option is available only for Low Voltage TereScope model 700/100. PoE eliminates a separate DC power supply cable at each Access Point (AP) location, i.e., it allows f or a single Ethernet cable providing both data and power to be run to each AP instead of two separate cables, one for power and the other for data. There are two types of PoE connections. One type utilizes all 8 wires of the Ethernet cable. The wires that are connected to pins 1, 2, 3, and 6 carry both power as well as data. T he other type utilizes the four wires that are connected to pins 1, 2, 3, and 6 for carrying data, and the four other wires that connect to pins 4, 5, 7, and 8 for carrying power. Pin 4 is shorted to pin 5 and these are connected to the (+) terminal of the power supply. Pin 7 is shorted to pin 8 and these are connected to the (-) terminal of the power supply. Both are floating isolated voltage as is usual for a -48V Telecom supply. TereScope model 700/100 with PoE option supports this second option only (as required per IEEE 802.3af standard) so proper connection to this pins should be provided. The TereScope model 700/100 can be connected by any of the following three methods:

1. TereScope model 700/100 with PoE option is connected directly to PoE-enabled equipment –The only needed part is a straight (non-cross) Category 5 jr 5e cable, which will also supply power to the AP.

2. TereScope model 700/100 with PoE option connected to non-PoE-enabled equipment through an external PoE adapter. The PoE adapter couples an Ethernet Line and DC Power (usually -48 VDC – see low voltage power requirement in Appe n d i x A : s p e c i f i c ations) o n t o a n 8 - w i r e straight (non-cross) Category 5 or 5e cable, as shown in Figure I.1. The other end of the PoE cable is connected directly to the TereScope model 700/100 with the PoE option. Adapters to be used with the TereScope are required to meet the IEEE 802.3af standard. Examples of brands of such adapters are: HyperLink Technologies BT-CAT5-P1, PowerDsine 6001. These two types of adapters are commercially available. This connection is illustrated on Figure I.1.

TereScope model 700/100 with PoE option connected to non-PoE-enabled equipment. In this case 8-wire straight (non-cross) Category 5 or 5e cable at the equipment side should be split on two wires groups. One group with standard pins 1, 2, 3, and 6 and carrying data to non-PoE enabled equipment. The other should be with four wires that connect to pins 4, 5, 7, and 8 for carrying power using external 48V power supply. Pin 4 is shorted to pin 5 and these are connected to the (+) terminal of the power supply. Pin 7 is shorted to pin 8 and these are connected to the (-) terminal of the power supply.
