Rx Card Description
Up to four fiber inputs are received using discrete Rx fiber optic module
subassemblies which can be fitted with various connector types as ordered.
The received inputs are routed to the crosspoint.
The crosspoint allows the up to four fiber inputs to be routed to four 75
Ω
BNC output ports fiber outputs per card module as specified in Overview (p.
1-1). The crosspoint can allow multiple outputs to serve as a DA with the
same input fiber source being applied to multiple BNC outputs.
Via card hardware switches or remote control, reclocking and automute can
be disabled (on an individual channel-by-channel basis) to allow signals
lower than 19 Mbps from being rejected as noise. The reclocker can manually
be set to bypass operation to reliably pass non-SMPTE signals (see
Non-SMPTE Signal Handling above).
