FCC, Safety and Service
Information
FCC Licensing
FiberLeap operates as an unlicensed device under FCC Rules, Part 15, Low Power
Communication Device Transmitter.
FCC Part 15 Rules Compliance
This Device complies with Part 15 of the FCC Rules. Operation is subject to the
following conditions:
• This device may not cause harmful interference
• This device must accept any interference received, including interference that
may cause undesired operation.
The FiberLeap Access unit has no user accessible controls and may not be
modified or altered in any way. Changes or modifications to the equipment could
void the user’s warranty.
FCC RF Exposure Compliance
The Federal Communications Commission (FCC), with its action in General Docket
93-62, November 7, 1997, has adopted a safety standard for human exposure to
Radio Frequency (RF) electromagnetic energy emitted by FCC regulated equipment. Telaxis subscribes to the same safety standard for the use of its products.
Proper operation of this equipment will result in user exposure far below the Occupational Safety and Health Act (OSHA) and Federal Communications Commission
limits.

About this
Manual
A FiberLeap fiber extension link consists of:
• FiberLeap Access units (2) with Mast Mounting Assembly Kit
• FiberLeap Interface Panels (2)
• FiberLeap System Cables (2)
The two Access Units are mounted within direct visual LOS (Line-of-Site) of each
other. Each of the two Access Units is connected to an Interface Panel (located
indoors), by means of a System Cable. The Interface Panels connect to the fiber
optic network (see Figure 1).
This Installation and Operation Manual provides instructions on how to install
the Access Unit on one end of the Link, which is then repeated for the second
end of the link. This installation procedure assumes that the necessary
rooftop mast for mounting the Access Unit, the System Cable and the
FiberLeap Interface Panel have already been installed.

Before initiating the actual installation of the Access Unit, certain other activties
should already have been accomplished. These include:
1. A Site Enginering Study – This study would have been initiated by a site survey
to determine all the physical and environmental constraints of the installation.
The engineering study ensures that the performance of the data link can be
met and specifies the details of the installation, i.e. the location of the Interface Panel, the mount/mast for the Access Unit and its location, identification
of the power source, length of the System Cable, length of the wireless link,
far end Access Unit location, etc.
2. Installation of the Rooftop Mast for the Access Unit – A suitable mast, 2.5
to 4.0” O.D., of sufficient height to meet the Access Unit mounting height
requirement specified in the engineering study must have been installed. This
mast must be braced or ballasted to survive high winds and grounded to the
rooftop lightning protection system in accordance with NEC or local regulations.
3. Installation of the System Cable – This installation must have been completed
in conformance with building requirements and governing codes by trained
and licensed installers.

Getting Started (cont.)
4. Installation of the Interface Panel – The Interface Panel should be either rack or
wall mounted in a suitable location in the Equipment Room to allow easy
connection to the ADM and the dc power source.
5. Review of Installation Details – The installer should review the engineering
study to assure an understanding of all the installation requirements. This
includes the Access Unit type ( A or B), mounting height, LOS (Line-Of-Site)
direction to the far end of the link, antenna polarization (Horizontal or
Vertical) and ADM data source identification.

Multiple Access Units
with Different and
Same LOS
The site engineering study specifies the physical requirements for mounting the
Access Unit and the installer must refer to that document to determine the predetermined parameters for properly installing the Mount Assembly and Access Unit:
• height above the roof deck
• direction of the LOS (visual sight line link far end)
• Access Unit type at each link end (A or B)
• Access Unit polarization (handle orientation)
Note: An installation involving two Access Units (links) on the same mast and
pointing in different directions usually requires both Access Units positioned for
horizontal polarization (Access Unit handles oriented horizontally). An installation involving two Access Units (links) on the same mast and pointing the same
direction, i.e. at the same link far end, requires one Access Unit positioned for
horizontal polarization (Access Unit handle oriented horizontaly) and the second
Access Unit positioned for vertical polarization (Access Unit handle oriented
vertically). See Figure 2.

Make Final LOS
5
Adjustment to
FiberLeap
Access Unit
The purpose of this step is to adjust the LOS (Line of Sight) of the Access Unit to
maximize the signal level. During this step, the second FiberLeap Access Unit at
the far end of the link must also be installed and powered ON. A continuous TX
data signal must also be present at the far end link. For purposes of Final LOS
alignment and signal optimization, a BERT (Bit Error Rate Tester) or an ADM with
BERT capability may be used to feed a SONET test pattern into the OC DATA, TX
input connector of the FiberLeap Interface Panel at the far end. Refer to Figure 7
unless otherwise noted.
1. Connect a dc voltmeter to the BNC connector on the rear of the Access
Unit using a BNC-to-test lead adapter. The voltmeter should read a dc voltage
of between 0.5 to 5.0 volts (see Figure 10).
2. Slacken the 2 azimuth clamp bolts on the Mount 1/2 turn. Using the
Azimuth Adjustment Bolt, adjust the azimuth LOS until the reading on the
voltmeter is at a maximum. It is advised that, in order to ensure the true
maximum, you should adjust through the maximum (peak voltage) until
the voltage clearly begins to drop and then adjust back until the maximum is
attained again (see Figure 11).
3. Tighten the 2 Azimuth clamp bolts on the Mount while observing the
voltmeter reading to ensure the azimuth alignment does not change while
tightening. Tighten bolts to 22 N-m (16.2 lb-ft).
4. Slacken the 4 Elevation clamp bolts on the Mount 1/2 turn. Using the
Elevation Adjustment Bolt, adjust the elevation LOS until the reading on
the voltmeter is at a maximum. It is advised that, in order to ensure the true
maximum, you should adjust through the maximum until the voltage clearly
begins to drop and then adjust back until the maximum is attained again.
5. Tighten the 4 Elevation clamp bolts on the Mount while observing the
voltmeter reading to ensure the elevation alignment does not change. Tighten
Nuts to 22 N-m (16.2 lb-ft).
6. Repeat steps 1 through 5 (above) to guarantee optimum alignment for
maximum signal strength.

Test the Link6
Prior to placing link in service for network traffic, the link should be tested for
BER using standard procedures for fiber optic cables.
The Installation Record (see page 17) and Warranty Registration should be
completed with pertinent installation information.

Operation
5
Operation of a FiberLeap link is quite simple. There are no user controls or
adjustments possible except for the ON/OFF switches on the Interface Panels at
each end of the link, and aiming the LOS (alignment) of the Access Units. Once
turned ON, the units are fully operational.
If SONET data is being supplied by the network to the OC TX connector at the
Interface Panel, the Access Unit will transmit that data to the link far end Access
Unit. Absence of a valid SONET signal will mute the transmitter.
In the event of network alarms, refer to the FiberLeap Troubleshooting Guide.
Please note that any attempt to open or modify a FiberLeap Access Unit will void
the warranty.
Inspection and Maintenance
6
Routine Inspection of the FiberLeap Access Unit and exterior portions of the
Cables should be performed at least once per year to check for loose hardware,
damage, corrosion or other disturbance to the installed hardware. Any damage,
corrosion or conditions not conforming to the original installation should be
corrected immediately.
Replacement of an Access Unit, Interface Panel or Cable, or any realignment of
either of the two FiberLeap Access Units requires a retest for BER (see pages 14-15).
