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 Channel Fiber to Electrical) Converter modules are
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 RU GeckoFlex frame. Each module can multiplex and
demultiplex up to 9 fiber channels over one fiber.
The following features are available with each module:
• Optical multiplexer/demultiplexer for combining signals on a single
fiber.
• Provides up to 8:1 or 1:8 multiplexing/demultiplexing using CWDM
technology.
• Provides an expansion port (EXP) to accept a ninth 1310nm signal for
9:1 multiplexing.
• Up to ten 8939FCA or 8939FCB modules (or any mix depending on the
application) can be housed in a GeckoFlex frame, providing up to 80
channels of optical multiplexing or demultiplexing per 2 RU frame.
• The module is a passive optical device for reliable service.
