Scheme for remote control of the output power of a transmitter in a smart SFP transceiver

摘要

A scheme is described for remote control of the output power of a transmitter in a smart SFP (or SFP+, or XFP) duplex (or BiDi, or SWBiDi) transceiver in a communication system using an operating system with OAM and PP functions, an OAM, PP & Payload Processor, a transceiver, an optical power meter (optional), a BERT, and an optical link in the field.

1. A method for optimizing a communication system comprising:
remote control of output power of a transmitter in a first transceiver in a communication system, said communication system comprising an operating system with Operation, Administration, and Maintenance (OAM) and Protocol (PP) functions, an OAM, PP & Payload Processor, a second transceiver, a Bit Error Rate Test (BERT) equipment, and an optical link, wherein remote control of output power of the transmitter in the first transceiver comprises: configuring the first transceiver to be in a loopback mode;enabling the BERT to transmit a pseudo-random (PRN) bit stream to the first transceiver, the first transceiver transmitting the PRN back to the BERT for bit error (BER) measurement, and recording of the measured BER;the first transceiver transmitting its output power to the second transceiver; andthe second transceiver sending an output power adjustment message to the first transceiver, and the first transceiver adjusting its output power according to the output power adjustment message.
