28 8943FC — Instruction Manual
Installation
CWDM 16 Channel Configuration
The 8943FC can also be used with the 8939FCA and 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 expansion
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 only using
a different set of CWDM fiber optic SFP devices with frequencies pairs from
1310nm to 1450nm.
