Receiver Description 
 
 
 
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. 
 
Single 2:1 on Primary + Single 1:1 on Secondary 
This mode is a combination of the 2:1 and 1:1 modes described above. Referring to 
the diagram below, one 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. The 
other EDR transmitter digitizes a single RF signal (RF 1). At the receiver, the serial 
streams from two separate transmitters are deserialized and converted back to their 
two analog RF components. The combined Transmitter 1 signal (RF 1 + RF 2) is sent 
to RF port A, and the Transmitter 2 signal (RF 1) is sent to RF port B on the back of 
the module.
