1. An optical transceiver module, comprising:
- an optical transmitter assembly including a laser device configured to produce an optical signal in response to a laser current, wherein the optical signal has at least one predefined characteristic;
a laser driver circuit configured to produce the laser current for use by the optical transmitter;
an optical receiver assembly; and
a controller circuit configured to receive a rate select signal that indicates a plurality of operational data rates for the optical transmitter assembly, and that is configured to generate at least one control signal for use by the laser driver circuit, wherein the at least one control signal causes the at least one predefined characteristic of the optical signal to be set according to the rate select signal.

Abstract
Systems, devices and methods are disclosed for adjusting the operating characteristic of an optical signal transmitted by an optoelectronic device based on the operational data rate, as is indicated by a ‘rate select’ signal. The rate select can be generated automatically, or can be transmitted from a host device. One example of an operating characteristic that can be adjusted is the optical modulation level of the transmitted signal.
