8935CF 4 Channel Electrical to 
Fiber Converter Module

Introduction

This manual covers installation, configuration, and operation of the 8935CF 
4 Channel Electrical to Fiber Converter module.

Module Features

The 8935CF module is a four channel electrical to optical converter (dual 
transmitter) with both electrical and fiber optic outputs. The module can 
accommodate a variety of high definition video inputs as well as DVB/ASI, 
AES, and GVG audio TDM interfaces.

The following features are available with this module:

•

Two module set including a hot-swappable front and rear module and 
up to two single mode SFP dual transmitter fiber optic submodules 
mounted on the front module. 

•

Up to ten 8935CF modules in the same 2 RU GeckoFlex frame.

•

Four electrical BNC inputs to up to four fiber optic outputs and an iden-
tical electrical BNC output for each channel.

•

Re-clocking for stable long distance signals or re-clocking bypass for 
non-SDI signals.

•

Supports both HD or SD formats and passes embedded audio present 
in the incoming video stream.

•

CWDM (Coarse Wavelength Division Multiplexing) capability when 
combined with 8939FCA Passive CWDM Optical Mux/Demux 
modules and 8935FC 4 Channel Fiber to Electrical Converter modules 
and other fiber-ready modules.

•

SNMP and product health monitoring is supported through the 
8900NET module with applications such as NetCentral.

•

Software updating using the NetConfig Networking application.
