Light Link ® Series 3

RPQRM-Return Path Quad Receiver Module

The Light Link ® Series 3 return path quad receiver module (RPQRM) is designed to plug into PBN's optical communications mainframe system (OCM).

This unit incorporates four independent optical return path receivers that operate at any wavelength between 1300...1610 nm. This unit also suits CWDM and DWDM applications.

The user can set each receiver individually for operation in either manual gain control (MGC) mode or automatic gain control (AGC) mode. In AGC mode the receiver employs a 4.5 MHz pilot detection to maintain its constant gain. There is also an FSK demodulator option, which allows for complete field node status monitoring. This feature can automatically detect the type of connected field node, being an AMCP1315, ODN1315, PBN-DN1, CPON, or any other compatible optical node.

Comprehensive status monitoring of each receiver within the module is available via the OCM user interface. The RPQRM extracts the field node data, including its own operational parameters for display at the OCM user interface and the NMS3 network manager. This allows complete supervision of the connected optical field nodes. The status is reported through the network management system.
