RLM - Return Laser Module for AMCP1315

The RLM return path laser module is a plug-in transmitter designed to fit into the AMCP1315. The RLM provides an economic solution for upstream transmission of DOCSIS return data or other two-way HFC applications.

The plug-in module is used together with a diplexer inside the AMCP1315 to suit a variety of frequency band-splits. This makes the AMCP1315 optical node a versatile unit for connecting multi-apartment buildings (MDU).

The RLM can be optioned for two different modes of status monitoring:

1. The pilot-only model verifies if the AMCP1315 has a valid optical input. If it doesn't, the laser or the pilot tone is switched off. This can be detected at the headend site as a remote alarm condition. The operation mode is jumper selectable on the RLM module.

2. The SMS (Status Monitoring System) model sends a continuous repeated data stream to the associated RP4RM return path receiver. The data is then decoded and made available to the readout on the OCM chassis and the NMS3 network management system.

• Plug and play optical laser and diplexer modules.

• Return bandwidth of 5ü200 MHz available, limited only by plug-in diplexer.

• High optical power output with outstanding DOCSIS performance, permitting higher speed modulation modes in the upstream path.

• Fully compatible with all AM, FSK, QAM, QPSK and FM transmission systems for 1310 nm and 1550 nm.

• Selection of FP and DFB lasers available, including CWDM wavelengths.

• Choice of frequency band splits via the AMCP1315 diplexer options.

• LED indicators monitoring the presence of optical output power and laser bias current. Plus a summary of the alarm status when optioned with SMS.

• FSK status monitoring option via 4.5 MHz pilot carrier and associated RP4RM return path receiver. No transponder needed.
