8943FC — Instruction Manual
Installation
To utilize this 9 channel Mux/Demux application, the following Grass
Valley modules are needed:
•
Two 8943CF 4 Channel Electrical to Fiber Converter modules with one
of each type of CWDM SFP device
•
Two 8943FC 4 Channel Fiber to Electrical Converter modules with one
of each type of CWDM SFP device
•
Two fiber-ready Grass Valley GeckoFlex modules with 1310nm SFP
devices
As shown in the detailed block diagram in
8943CF (Electrical to Fiber converters) at Location A are used to feed 8
channels of video to an 8939FCA. To utilize this application, one of each of
the following four CWDM SFP device types must be installed on the two
8943CF modules:
•
SFP-CWDM3G-1-K Dual Transmitter (1470nm/1490nm frequencies)
•
SFP-CWDM3G-2-K Dual Transmitter (1510nm/1530nm frequencies)
•
SFP-CWDM3G-3-K Dual Transmitter (1550nm/1570nm frequencies)
•
SFP-CWDM3G-4-K Dual Transmitter (1590nm/1610nm frequencies)
Note
The four SFP devices can be installed in any location on the two 8943CF
modules as long as the outputs are cabled to the correct frequency input on
the 8943FCA. The installation configuration shown here is for clarity only.
The 1310nm fiber output from a Grass Valley GeckoFlex module is cabled
to the EXP (Expansion) port on the 8939FCA.
The 8939FCA module multiplexes these 9 frequencies down to a single
output from the COM port. A single fiber cable carries these 9 video fiber
channels to the COM port of the 8939FCA at Location B.
The 8939FCA at Location B acts as a demultiplexer and outputs 9 fiber
video channels to two 8943FC (fiber to electrical) modules, each with two
SFP-13103G-M1DRX-K Dual Receiver SFP devices installed and a Grass
Valley fiber-ready module. The dual receiver SFP device will accept input
frequencies from 1270nm to 1610nm.
concerning the attenuation
needed depending on the length of cable run between 8939FCA COM
ports.
