Systems and methods for interfacing optical line terminals with optical modules

Abstract:

Circuitry of an optical line terminal (OLT) can be controlled to be compatible with optical modules of different optical protocols having different electrical connectivity requirements. In some embodiments, the OLT has a controller that is configured to communicate with an optical module plugged or otherwise mated with a socket of the OLT in order to discover a module type of the optical module. Based on the detected module type, the controller is configured to control the electrical characteristics of the OLT circuitry so that it is compatible with the electrical and operational requirements of the optical module. Thus, the OLT is compatible for use with any of a plurality of optical module types.
