LNKFIB-H03 and LNKFIB-H04 Head-End Module Connections
The LNKFIB-H03 Head-End has two Downlink RF Inputs providing the signal for
eight Downlink Optical Outputs arranged as groups of four, "A" and "B". It also has
eight Uplink Optical Inputs combined in two groups of four providing RF Outputs "A"
and "B". The RF and optical connections are all on the rear panel. The Group-of-
Four RF Input and Output combining inside the Module alleviates the need for
external combining / splitting.
