8939FCA/8939FCB Fiber Optic Mux/Demux Modules

Introduction

This manual covers installation and operation of the 8939FCA and
8939FCB Fiber Optic Mux/Demux modules.

For purposes of this manual, the Grass Valley 8943CF (4 Channel Electrical
to Fiber) and 8943FC (4
used to demonstrate the use of the 8939FCA and 8939FCB modules. These
modules handle signals with bit rates up to 3 Gb/s.

Note The first generation Grass Valley 8935CF (4 Channel Electrical to Fiber) and

8935FC (4 Channel Fiber to Electrical) Converter modules can also be used
with the 8939FCA and 8939FCB modules. These modules handle signals with
bit rates up to 1.5 Gb/s. Status reporting on these modules may vary.

Module Features

The 8939FCA and 8939FCB modules are bi-directional optical CWDM
(Coarse Wavelength Division Multiplexing) multiplexer/demultiplexer
modules for the 2

Module Placement in the GeckoFlex Frame

Each 8939FCA and 8939FCB model consists of a single passive rear module
that can only be installed in the rear of a GeckoFlex frame.

Installation of the 8939 rear module is a process of:

1. Placing the 8939 module in an unused rear frame slot,

2. Cleaning all fiber optic connectors and cable end faces with required

cleaning kit (see Fiber Optic Cleaning Requirement on page 11), and

3. Cabling the signal ports.

All GeckoFlex front and rear modules can be inserted and removed from an
GeckoFlex frame with power on.

There are ten front and rear cell locations in the 2 RU GeckoFlex frame
