Abstract:
1. A Small Form Factor Pluggable (XFP) electro-optical transceiver comprising a pluggable module having a module housing, an electrical interface, and an optical interface, the pluggable module comprising within the module housing: a transmitter module including an electro-optical source for converting an electrical input signal received via the electrical interface into an optical output signal; a receiver module including an opto-electrical detector for converting an optical input signal received via the optical interface into an electrical output signal; a sensor associated with said receiver module for sensing a bit rate of said optical input signal; an adaptation unit associated with said transmitter module for varying an operating power parameter of said transmitter module; a processing unit in communication with said receiver module and said transmitter module for determining said operating power parameter of said transmitter module based on said bit rate, and for controlling operation of said adaptation unit in order to adapt operation of said transmitter module in accordance with said operating power parameter, wherein the processing unit is selectively configured to determine said operating power parameter based on a control signal received from a master controller via a digital bus.
