1. A system for safe operation of an optical assembly, the system comprising:
an external light module emitting a continuous wave laser signal through an output port;
an optics module having an input port, an optical transmission port, an optical receiver port, a photonics chip, and a memory, the photonics chip generating a modulated optical signal from the continuous wave laser signal received at the input port and modulating optical signals transmitted through the transmission port and received optical signals from the optical receiver port, wherein the memory stores the power level of the continuous wave laser signal received by the optics module;
an optical jumper for coupling the output port with the input port;
a controller operable to set the external light source at a low power level and transition the external light source to a high power level when the stored power level of the continuous wave laser signal received by the optics module exceeds a predetermined level; and
a communication bus coupled between the controller and the external light source module to allow the controller to set the external light source power level.
