Method and system for adaptively setting a transmitter filter for a high speed serial link transmitter

摘要

A communication device may be operable to determine, in an optical module, a signal quality associated with each of one or more host transmitter filters in a host circuit. The signal quality may be communicated from the optical module to the host circuit via a management interface. The communication device may control, in the host circuit, configuration of each of the host transmitter filters based on the signal quality. The communication device may be operable to determine, in the host circuit, a signal quality associated with each of one or more module transmitter filters in the optical module. The signal quality associated with each of the module transmitter filters may be communicated from the host circuit to the optical module via the management interface. The communication device may control, in the optical module, configuration of each of the module transmitter filters based on the signal quality.

1. A method for communication, the method comprising: in a communication device comprising a host circuit and an optical module, the host circuit comprises a first plurality of transmitters and a first plurality of receivers, the optical module comprises a second plurality of transmitters and a second plurality of receivers, and the host circuit and the optical module are communicatively coupled by a management interface connecting the host circuit to the optical module, an electrical transmit path connecting the first plurality of transmitters to the second plurality of receivers, and an electrical receive path connecting the second plurality of transmitters to the first plurality of receivers:
determining, in said optical module, a signal quality associated with individual host transmitter filters associated with the first plurality of transmitters in said host circuit; communicating said determined signal quality from said optical module to said host circuit via the management interface; and adjusting, in said host circuit, one or more settings of the individual host transmitter filters based on said determined signal quality.
