28 8943CF — Instruction Manual
Installation
CWDM 16 Channel Configuration
The 8943CF and 8943FC can also be used with the 8939FCA and the
8939FCB to provide 16 channels of video over a single fiber connection.
As shown in the simple block diagram in Figure 23 , the two 8939FCB
module COM ports can be connected to the 8939FCA module EXP ports to
provide another eight channels of video, for a total of 16 channels over one
fiber.
The 8939FCB must be set up in a similar manner as the 8939FCA
(CH1 – CH8) only using a different set of CWDM fiber optic SFP devices
with frequencies pairs from 1310nm to 1450nm (CH9 – CH16).
