8935CF — Instruction Manual 19
Installation
Electrical Inputs
Connect a signal conforming to the to the specifications given in Table 6 on
page 47 to the coax inputs for Channel 1 -4 as labeled on the rear of the
8935CF-R module.
Electrical Outputs
There are four electrical coax video outputs corresponding to Channel 1-4
as labeled on the rear of the 8935CF-R module.
Fiber Optic Outputs
There are four fiber optic output ports corresponding to Channel 1-4 as
labeled on the rear of the 8935CF-R module (
Figure 10 on page 18 ).
Note Before making any fiber connections, follow the required fiber optic cleaning
recommendations given in
Fiber Optic Cleaning Requirement on page 10 .
For the fiber output ports, the 8935CF-R rear module shall follow the
channel allocation convention shown in
Figure 11 . Optical channel 1 and
channel 3 are mapped to the B side of standard duplex fiber connector and
channel 2 and channel 4 are mapped to the A side of a standard duplex fiber
connector.

8935CF to 8935FC Connections
When connecting an 8935CF module directly to an 8935FC (point-to-point),
a non-crossing duplex fiber cable is required shown in
Figure 12 . Refer to
Attenuation Requirements on page 18 for cable length attenuation notes.
Non-crossing is in reference to the logical A/B nomenclature associated
with the duplex connector illustrated below. Side 1A connects to side 2A
and side 1B connects to side 2B. Refer to
Figure 12. Non-Crossing Duplex Fiber Cable
