Introduction to the Fiber Optic Modem

General Overview

Definitions and Terms

The Fiber Optic Modem is used to simplify field wiring and increase transmission distances by converting system copper-wired interfaces to fiber optic connections. It has field wiring connections for the Digital Audio Riser, Analog Audio Risers, RUI, and 4120 Network. A Modem pair replaces copper wiring between any two points including node-to-node, node-to-transponder, and transponder-to-transponder. The Modem is invisible to the connected equipment, and does not need to be programmed in as part of the job (except for power supply current calculations). The Modem combines the input signals so they can be communicated over one fiber in both directions.

In general, the Modem installation is accomplished by simply connecting the wires that would normally be routed between cabinets to the Modem. The only additional steps required when using a Modem rather than copper are:

1) Configuring the DIP switches and jumpers according to the application.

2) Routing the “x-link” wire if the system has Class A Analog Audio or Class A RUI.

Modems are always installed in pairs. There are four versions: a “right-port” and “left-port” version for each type of fiber; left and right for single-mode and a left and right for multimode. Any Modem link must consist of one of each type. The order in which Modem pairs are installed is arbitrary. A “left-to-right” Modem pair can be followed by another “left-to-right” pair, or by a “right-to-left” pair.

Enhanced Analog Audio (EAA): EAA refers to a reformatted version of the Analog Audio Riser that is wired between modems. In an EAA system, modems pass the Riser to the next modem as a digital signal via the DAR channel. EAA disallows the use of Analog Channel 2. Generic: A “Generic” modem is any modem that is not a Head-End or Tail-End modem. In a Class B configuration, all modems are generic. Head end: A “Head-End” modem is a modem with an electrical connection to the primary side of the head-end cabinet. If there are any fiber optic links between a modem and the head-end cabinet, then that modem is not a head-end modem. A modem with additional nodes or transponders between itself and the head-end cabinet, but no optical links, can still be a head-end modem. Local side: The “local side” of any configuration refers to all portions of the wiring loop that are electrically connected to the head-end cabinet. Any wiring that is isolated from the head end via one or more optical links is not electrically connected, and therefore considered “remote.”

NIC: Network Interface Card. Remote side: The “remote side” of any configuration refers to all portions of the wiring loop that

are not electrically connected to the head-end cabinet. Any system that is electrically connected to the head end (no optical links) is considered “local.”

RIC: Riser Interface Card. Tail end: A “Tail-End” modem is a modem with an electrical connection to the secondary side

(also known as a Class A return) of the head-end cabinet. If there are any fiber optic links between a modem and the head-end cabinet, then that modem is not considered a tail-end modem. A modem with additional nodes or transponders between itself and the head end, but no optical links, can still be a tail-end modem. X-link: The “x-link” is a pair of RUI or Analog Audio Riser wires that connect head-end and tailend modems to one another. The link is required to maintain an electrical connection between the primary and secondary sides of the local-side wiring loop. (X-link definition is continued on the next page.)

Definitions and Terms

Digital Audio Riser Overview

Analog Audio Riser Overview

X-link (continued): X-link connections are only required in Class A Analog Audio and Class A RUI configurations. They are not required for the Digital Audio Riser interface, a Network interface, or for any other Class B configuration. Where required, the x-link connection maintains Class A supervision even though the remote side of the fiber link is electrically isolated. The xlink is only wired between the two modems that are electrically connected to the head-end cabinet via RUI or riser wiring. (It is still considered electrically connected even if there are transponders between the modem and the head-end cabinet).

The Modem replaces copper wiring between a Digital Audio Controller and a Digital Audio Riser Interface Card, or between Digital Audio Riser Interface cards. Modem connections can be used between transponders, or between nodes in Network systems.

The Modem replaces copper wiring between an Analog Audio Controller and an Analog Audio Riser Interface Card, or between Analog Audio Riser Interface cards. Modem connections can be used between transponders, or between nodes in network systems. The Modem can be configured for 10 Vrms audio risers (standard), 1 V peak-to-peak audio risers, or 0.707 Vrms.

The standard analog audio usage of the fiber modem imposes a 6-modem-pair limit on system size. The Enhanced Analog Audio (EAA) feature removes this limitation by keeping a version of the analog stream digital through the wired link. Using EAA imposes other limitations, however, that include the following:

• Limitation to one analog channel only (Channel 1).

• Requires that the EAA wire (connected to DAR terminals) be close nippled (since it is

unsupervised).

4120 Network Overview

RUI Overview

Fiber Modem Audio Expansion Board

• Excludes the usage of the DAR interface for the Digital Audio Riser because the DAR

interface is used as the EAA channel.

The Modem can replace either one or two wired connections between Network Interface Cards. It can replace the right-port wire, the left-port wire, or both. The Network Interface Cards that the Modem will connect to must have wired media cards installed. The Modem can be used to replace wiring between any two NICs, and it can also be used in lieu of a Physical Bridge. When the Modem is used in lieu of a Physical Bridge, the network topology appears as a typical ring configuration since the Modem effectively replaces two wires between the local and remote node.

Refer to Figure A-18 that shows an Interconnected Loop without a Physical Bridge. The Interconnected Loop normally requires a Physical Bridge but doesn’t in this diagram because modems are used.

Note that references to 4020, 4120, and 4100 Legacy Fire Alarm Panel systems are for retrofit applications only. None of these Fire Alarm System models have been listed to the Ninth Edition of UL864.

The Modem replaces copper wiring between a CPU Motherboard and Transponder Interface card, between Transponder Interface cards, or between a RUI card and Transponder Interface card. Maximum of eight pairs of Modems for RUI if wired Class A.

The Audio Expansion Board allows the Fiber Optic Modem to interface with 4100 Legacy Audio systems. The card has two channels, each of which are selectable for 70 Vrms or 25 Vrms risers. The card converts the 70 Vrms or 25 Vrms to a 10 Vrms signal to be used by the modem. The card connects to the modem via a ribbon harness.

Fiber Modem Audio Expansion Board

Description

The Fiber Modem Audio Expansion Board is a module that allows the modem to interface to a 4100 audio system. It attaches to the Fiber Modem via a ribbon cable and riser wires. The 4100 audio system uses 25 or 70.7 Vrms risers. The expansion board converts these levels to 10 Vrms risers for use on the Fiber Modem.

The Audio Expansion Board mounts in either a 4100 cabinet on its mounting bracket, or in the Fiber Modem Expansion Cabinet (refer to Figure 5 and Table 1 for details). The module wires to a 4100-style signal card in either Class A or B configurations, or directly to the amplifier's output in Class A only. Refer to Figure 12 for wiring details of the expansion board. All wiring from the expansion board must be close nippled.

Mounting Instructions

MODEM CARD

The modem must always be mounted in a 4100U or 4100ES main panel, transponder cabinet, 4100 cabinet, Remote Expansion Cabinet (4190-9021, -9022, -9024, -9025), or any other closenippled cabinet. It is either installed in the same manner as other standard panel 4-inch (102 mm) X 11-inch (279 mm) option cards (except that there is no PDI connection), or mounted using the mounting plate in the 4100 or any other close-nippled cabinet. In either the case, you must install the modem with the fiber optic transceiver pointing down so as to provide proper airflow to the heat sinks. See Figure 3.

The Remote Expansion Cabinet is required when the modem is used with a 4010, 4010ES or 4020 (Network Communications only application). When the modem is used with a 4100, 4100U or 4100ES system, the expansion cabinet can be used if space within the system box does not permit the installation of the modem(s) in the main cabinet. In any case, the modem must be close nippled to its host cabinet.

In contrast, the Modem Audio Expansion Board can only be mounted in an Expansion Cabinet, in a 4100 bay using the mounting plate, or close nippled in a transponder cabinet.

Wiring

Overview

All Modem wiring is supervised and power-limited.

The following Modem wiring must be within a system box or close-nippled to a system box:

• Digital Audio Riser

• 24V Card Power

• 4120 Network Left Port

• Analog Audio Risers

• RUI

The following Modem wiring is allowed to be routed external to a system box:

• 4120 Network Right Port

• Analog Audio Riser X-link

• RUI X-link

The remainder of this section covers the actual fiber connection and then details wiring specifications with accompanying wiring diagrams for the 4120 Network, Analog Audio Riser, Digital Audio Riser (DAR), and RUI.

Note: Ferrite beads are required where the DAR, 4120 Network, and RUI wiring

enters or exits a system box. Except for the 4120 Network Right Port and the RUI X-Link, ferrite beads for all wires are supplied with their respective equipment. Ferrite beads for the RUI X-Link and the 4120 Network Right Port are supplied with the modem (Ferrite Bead Kit Part No. 742-940.)

Figure 6. Loop wires through bead as shown

Fiber Connection

The fiber optic cable uses a standard ST connector. When mating the connector to the Modem, be sure to align the connector’s key properly to avoid any undue stress to the Modem.

Caution: The fiber optic cable can be damaged easily. To prevent permanent damage to

the fiber, avoid bending radii smaller than 1.5 inches (38 mm), or as specified for your particular fiber optic cable.

4120 Network Wiring Specifications

These wiring specifications apply to the Modem’s 4120 Network Right Port only (the Left Port must be internal or use close-nippled wiring):

The distances listed below allow for the introduction of two lightning suppressors (TEPG Part# 2081-9027) into the communication line for installations where the wiring leaves the building. These distances are shown for 18 AWG (0.8231 mm2) and 24 AWG (0.2047 mm2) wiring at

57.6Kbps and 9600Bps.

57.6 Kbits per/second

Using 18 AWG (0.8231 mm2) fire-rated, shielded, twisted-pair cable, transmission distance is: 10,000 Feet (3,048 meters) (with or without Suppressor #2081-9027). Using 24AWG (0.2047 mm2) twisted telephone cable, transmission distance is: 7,000 Feet (2,134 meters) (with or without Suppressor #2081-9027).

9600 bits per/second

Using 18AWG (0.8231 mm2) fire-rated, shielded, twisted-pair cable, transmission distance is: 17,000 Feet (5,182 meters) (with or without Suppressor #2081-9027). Using 24AWG (0.2047 mm2) twisted telephone cable, transmission distance is: 12,000 Feet (3,658 meters) (with or without Suppressor #2081-9027).

Continued on next page

Page 22

Wiring, Continued

4120 Network Wiring Specifications

The specifications for the cables to be used in order to meet the above transmission distances are as follows:

18 AWG (0.8231 mm2) Fire-Rated, Twisted-Shielded Cable must not exceed a capacitance between conductors of 58pF per foot and not have a DC resistance greater than 6.385 ohms per 1,000 feet (305 meters).

24 AWG (0.2047 mm2) Twisted, Unshielded Telephone Cable must not exceed a capacitance between conductors of 22pF per foot and not have a DC resistance greater than 25.6 ohms per 1,000 feet (305 meters).

When using twisted-shielded pair, the shield is to be connected to Earth ground (Chassis). It is recommended that the shield be connected to Earth ground at one end of the link only (Left Port). When terminating the shield to Earth Ground, it is also preferable to connect it on the chassis as close to the exiting point of the back box as possible. Earth ground is also available on the external terminal block, and on the host’s port connectors. When using 0 V in lieu of Earth ground for shield connection, only one end of the link should be connected (Left Port).

Analog Audio Riser Wiring Specifications

These wiring specifications apply to the Modem’s Analog Audio Riser Wiring.

• Analog Riser wiring to/from the Modem must connect to either an Analog Audio

Controller or an Analog Audio Riser Interface card.

• The Analog Riser X-link can be wired external to the system box, and is part of the head-

end side of the wiring loop (that part of loop - 10,000-foot [3,048-meter] limitation).

• All wiring is 18 AWG (0.8231 mm2) to 14 AWG (2.081 mm2), twisted-shielded pair.

• Audio wiring is not to be mixed in the same jacket with other wiring (including other

audio wiring).

• AC voltage rating: 10 VRMS (maximum).

• DC voltage rating: 1 VDC (maximum).

• Maximum number of analog interface cards per audio riser: 98.

• Maximum of six pairs of Modems in series using standard analog audio.

• All wiring that leaves the building requires the 2081-9044 Overvoltage Protector at each

entry or exit to the building.

• Maximum wire distance: 10,000 feet (3,048 meters) per copper wired section (for

example, a 10,000-foot [3,048-meter] loop of copper could be connected to another 10,000-foot [3,048-meter] loop of copper if the two loops were electrically isolated via fiber optic cable).

• Wiring must be free of all grounds.

• All riser wiring is supervised and power-limited.

• “T” tapping is not allowed from the Modem.

• The DAR interface wiring, when used for Enhanced Analog Audio (EAA), must be close

nippled because it is not supervised.

Refer to Figure 8 for Modem to Analog Audio Riser wiring information and Figure 9 for Modem to Enhanced Analog Audio Riser wiring information.

Analog Audio Riser Wiring Specifications

Note 1: On the head-end modem in a Class A analog audio wiring loop, it is necessary to provide wired connections

between the riser’s terminal block positions and the x-link as shown in this diagram. If using 18 AWG (0.8231 mm2) or smaller wire, then make connections as indicated in this diagram. If using wire larger than 18 AWG (0.8231 mm2), then insert a short piece of wire into the terminal block positions and connect the riser and x-link wiring using a wire nut.

Note 2: For Enhanced Analog Audio (EAA) systems, do not make Riser 2 connections.

Enhanced Analog Audio (EAA) Riser Wiring Specifications

Enhanced Analog Audio (EAA) eliminates the restriction on the number of modem pairs that can be used in an analog audio system. In an EAA system, you can use only Riser 1 (Channel 1). EAA does not affect the content of the analog riser; it only affects the format of transmission throughout the modem chain.

Note: In an EAA system, modems transmit the analog riser via the EAA wiring or

the riser channels. If riser channels are used to pass the riser, the maximum number of modem pairs passing the riser over the riser channels is limited to six.

Enhanced Analog Audio (EAA) Riser Wiring Specifications

* E = EAA link. The bracketed fiber links have EAA wired close nippled between them. Multiple modem links can be counted as a single link for the purposes of calculating the total number of Standard Analog Audio links in a system (e.g. E3 above can be counted as one link even though it consists of 5 modem pairs).

Example of internal wiring in the system above:

EAA Combinational System

In some analog audio systems, more than six modem pairs might be required (therefore requiring EAA usage), but the topology will not allow for all modem-to-modem connections to be close nippled. You are permitted to have modem-to-modem connections made with external wiring; however, those links will not be using the EAA feature and therefore, will be counted toward the limit of six Standard Analog Audio modem pairs in a system. The example in Figure 10 shows such a system where connections between buildings are made with fiber, and intra-building connections are made with field wiring. Note that since EAA is used in the system, the restrictions it imposes apply to the entire analog audio system. Refer to Analog Audio Riser Overview section that appears earlier in this publication.

Connecting Power to the Modem

Where to Connect Power

4100U, 4100ES and 401ES

The Modem has two Core 4 connectors (P9 & P10) and a terminal block (TB1) for connecting 24 VDC power. (See Figure 1 and Figure 14 [on next page] for locations of Connectors P9 & P10 and Terminal Block TB1.) The source of card power to the Modem must be an uninterruptible source (such as card power), and not a resettable source such as AUX power. The Modem’s power must not be interrupted because all wired interfaces would fail during the power failure (roughly equivalent to disconnecting all the attached wires for the duration of the power failure). The intended installation in a 4100U, 4100ES or 4010ES system is to use Connectors P9 & P10. Because these two connectors are electrically identical, power can be daisy chained as needed in and out of the Modem. The connection can be made using a standard PDI bay-to-bay harness. Make your connection to the mating connector on the local power supply (SPS, RPS, XPS or MSS in the case of a 4010ES system). If the connector on the power supply is occupied (as may be the case in a Miniplex Transponder cabinet), then connect the Modem power harness to one of the PDI connectors on the PDI to which the power supply is connected.

NOTE: Do not use the daisy-chain connections for anything except modems. The communication-wiring portion of the harness is not connected to the modem and is not daisy chained between the connectors.

4100 (Audio [Expansion Board] and 4120 Network Only)

When connecting power to a 4100 system, connect TB1-1 and TB1-2 on the Modem to the system power supply:

• 24V…TB2-11 or TB2-12

• 0 V….TB2-9 or TB2-10

4010 (4120 Network Only)

When connecting power to a 4010 system, connect TB1-1 and TB1-2 on the Modem to auxiliary power (TB5) on the system board.

4020 (4120 Network Only)

Testing and Troubleshooting

General

Use this section as an aid in testing and troubleshooting a fiber modem pair installation. It should be noted that a fiber fault can cause a trouble on all connected media. A fiber fault must be resolved before any further troubleshooting or testing can be performed. The following general checkouts should always be performed upon installation of modem pair:

1. Verify that the “Fiber Fault” LED is not illuminated. If it is not, then the fiber connection

is operating. (See Table 12 and the Fiber Fault LED section [next page] for details on LED indications.) If it is illuminated, verify the following:

a. The modems are actually a mated pair. Perform this action by checking the

assembly number of the fiber optic transceiver board that mounts to the main board. For multimode fiber, one transceiver should be 566-714 (left port), and the other should be 566-715 (right port). For single-mode fiber, one transceiver should be 566-716 (left port), and the other should be 566-717 (right port).

b. The fiber optic cable is properly connected, and the connections are clean. c. The total attenuation and distance are within limits. d. If all of the above conditions are met and the Fiber Fault LED is still

illuminated, then it may be necessary to test the link using an OTDR. OTDR tests should be done using industry standard methods and industry standard pass/fail criteria.

2. Verify that the switch configurations are properly set. If the switches are set improperly,

the modem may not be in the proper mode, and may not be capable of entering a degraded mode or successfully report troubles to the connected equipment.

3. Verify that the wired connections are in the proper terminal block positions. For RUI and

Analog Audio (if used), be certain that the risers connect to the RUI and Riser positions and not the x-link connections. The only time anything should be connected to the x-link connections is in a Class A system between the head and tail-end modems.

Note: All wiring faults (shorts and opens) on a wired loop that is electrically isolated from the main panel by fiber will always be reported as an open on the panel side of the loop. Modems report this way to convey fault information back to the panel without causing a short circuit on the panel side of the loop.

LED Indications

Fiber Fault LED

The Modem has LED indicators as shown in Table 12. Refer to Figure 1 for LED locations.

Table 12. LED Indications

Reference Function Details

LED1 AAR1 FAULT Indicates a fault condition on Analog Audio Riser Channel 1. LED2 AAR2 FAULT Indicates a fault condition on Analog Audio Riser Channel 2. LED3 FIBER FAULT Indicates a failure of the fiber optic link. LED4 RUI FAULT Indicates a fault condition on RUI. LED5 POWER Indicates the presence of 24V card power. LED6 4120 TX R Flashes while data is actively being transmitted on the right

network port.

LED7 4120 RX R Flashes while data is actively being received on the right network

port.

LED8 4120 TX L Flashes while data is actively being transmitted on the left network

port.

LED9 4120 RX L Flashes while data is actively being received on the left network

port. ON when DAR transceiver is in transmit mode. OFF when in the

LED10 DAR TX

Note: The RUI and Analog Riser LEDs are intended as troubleshooting aids only. In some configurations, they will not indicate a fault on their wiring.

receive mode. Flashes when the Modem is searching for an active DAR (fault if flashing).

There are two severity levels for fiber faults. One level is a momentary fault that’s indicated by the fiber fault LED for any data error on the fiber. In a properly operating fiber link, momentary faults occur very rarely or never. If the fiber fault LED illuminates frequently (e.g., more than once in five minutes), then there may be a problem with the fiber link. The other level of fault is a fiber trouble. In this case, troubles are reported at the panel and the fiber fault LED illuminates much of the time or continuously; you definitely need to check out the fiber link. The goal for any link during installation is to have no illumination of the modem’s fiber fault LED.

Digital Audio Riser (DAR)

Use the “DAR TX” LED to aid in diagnosing DAR faults. If the DAR LED is OFF, then the DAR is in the receive mode. It remains in the receive mode if the DAR is not enabled or if the modem is actively receiving a DAR on the wired connection. If the DAR LED is ON, then the modem is actively transmitting a DAR on the wired connection. If the DAR LED turns ON and OFF at a 2second rate, then the modem is searching to find a DAR on the fiber and the wired interface.

In the event of a DAR fault, check the following:

1. The DAR enable switch is properly set.

2. The DAR LED is OFF on a modem receiving the DAR from the wired interface.

3. The DAR LED is ON for a modem transmitting the DAR to the wired interface.

Testing and Troubleshooting, Continued

Analog Audio

4120 Network

RUI

If the analog audio interface is not operating properly, verify the following:

1. The analog audio switches are properly set.

2. A good quality voltmeter can be used to measure the riser’s RMS voltage on the panel

side loop, and then be re-measured on isolated loops to determine what modem pair could be causing a fault. Any signal present on one side of a fiber connection should be present on the other.

3. The wired interface is connected to the proper terminal block positions.

4. The analog audio level select jumpers are properly set.

Note: A fault on the analog audio interface could result from a fault on a

separate-wired interface, and could be induced by a connected modem that’s indicating to the panel that there is a fault on an isolated wired loop.

If the network interface is not operating properly, verify the following:

1. The network switch settings are all properly configured.

2. The network connections are in the proper ports. A given network wire pair should

always enter either the left or right port of a modem, and leave via the mating modem’s opposite port (for example, in on left, out on right, or vice versa).

3. The network interface LEDs operate in the same way as those found on a network

interface card; that is, the TX and RX LEDs illuminate only while data is actively being passed in their respective directions.

If the RUI interface is not operating properly, verify the following:

1. The RUI configuration switches are properly set.

2. The wired interface is connected to the proper terminal block positions.

Note: A fault on RUI interface could result from a fault on a separate-wired

interface, and could be induced by a connected modem that’s indicating to the panel that there is a fault on an isolated wired loop.

System Checkout

A basic system checkout should always be performed on a new installation to verify that all modems are properly configured. Do a basic checkout because a wrongly configured modem could behave normally in normal mode, but not be capable of entering degraded mode or reporting troubles to the panel. Basic tests include introducing shorts and open circuits on each of the wired links within a system as well as interrupting each fiber optic link and verifying system operation.

*Required if analog audio interface is used. In digital audio systems, this fiber is only required

if multiple T-tapped nodes are wired from a single node (as is shown here in that 3 nodes connect to Node 1).

A Hub Configuration consists of a Main Loop with Nodes connected in a radial manner. In this configuration, the Modem connects the Hub Node to the Remote Nodes.

Hub Configurations for 4120 Network, Analog Audio, and Digital Audio are illustrated on the pages that follow.
