analog RF components, and then sent to the two RF connectors on the back of the 
module. RF 1 appears on RF port A, and RF 2 appears on RF port B. 

Note: The optical fiber must be plugged into the top receiver on the OPM. 

 

Referring to the diagram below, the EDR transmitter digitizes a single RF signal (RF 
1) into a serial stream and transmits it over optical fiber to the receiver. At the 
receiver, the serial streams from two separate transmitters are deserialized and 
converted back to an analog RF signal. The RF signal (RF 1) for each transmitter is 
sent separately to the two RF connectors on the back of the module. 

 

Referring to the diagram below, two EDR transmitters are connected to one receiver. 
Each EDR transmitter digitizes and combines two RF signals (RF 1 + RF 2) into one 
serial stream and transmits it over optical fiber to the receiver. At the receiver, the 
serial streams from the two separate transmitters are deserialized and converted 
back to their two analog RF components. Since the receiver only has two RF ports, 
the combined signals (RF 1 + RF 2) for each transmitter are sent to the two RF 
connectors on the back of the module.
