LLFR Forward Receiver

 

 
 

The Laser Link

®

 Forward Receiver (LLFR) receives optical signals, then converts 

them to RF and transmits them into the network.  Up to 7 modular forward path 
receivers can be housed in the Laser Link Mainframe, or 2 modules in the Laser Link 
Mini-Mainframe, offering compact installation, improved system reliability and a 
telemetry interface for Network Management (status monitoring). 
 
The ELLRR-S Reverse Receiver (ELLRR-S) receives analog or data upstream 
signals from a node or a hub location.  Up to 14 modular return receivers can be 
housed in the Laser Link Mainframe or 4 modules in the Laser Link Mini-mainframe, 
offering compact installation, improved system reliability and a telemetry interface for 
Network Management (status monitoring).
