LLFR Forward Receiver
Description
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).
