Return Path Quad Receiver Module - for OCMR

About the Product

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. A specialised RPQRM version is available for RFOG applications. 

The user can set each receiver individually for operation in either manual gain control (MGC) mode or automatic gain control(1) (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, ODN2P, ODN4P, CPON, DPON, MAU or any other compatible optical node.

Comprehensive status monitoring(1) 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.

Features

• Plug and play OCM module with four independent return path receivers.
• Bandwidth 5~200 MHz for the standard HFC model and 5~65 MHz for the specialized RFOG model
• 1300~1610 nm operating wavelength, to suit CWDM, DWDM and SCTE-RFOG applications.
• User selectable MGC or AGC.(1)
• RF pilot (4.5 MHz) based automatic gain control (AGC) (1) over fibre optic link with adjustable RF output level.*
• Can be configured for redundant return path applications via NMS3-Enterprise-II.
• Mute function with multiple level steps on individual receivers to suppress unwanted RF power levels due to ingress.
• Comprehensive status monitoring of individual receivers plus remote node status monitoring with SMS option.*
• FSK demodulator for automatic detection of field node type, with status monitoring.*
• NMS3-Enterprise-II network manager compatible, including RF power level and ingress management control.

(1) Pilot based AGC, remote node status monitoring, and FSK demodulator functions are removed on RPQRM-[X]-RFOG models.
