Patent ID: 8903246

Claim:
Optical sub-assembly, particularly TO-can, comprising: multiple pins extending from the outside to the inside of the optical sub-assembly; a light receiver or a light transmitter arranged inside the optical sub-assembly; a receiver circuit or a transmitter circuit arranged inside the optical sub-assembly and connected between the multiple pins and the light receiver respectively or the light transmitter, respectively, wherein the receiver circuit comprises a receiver communication interface in order to transform an output signal of the light receiver into a communication signal, wherein the transmitter circuit comprises a transmitter communication interface in order to transform a communication signal into an input signal of the light transmitter; a squelch circuit arranged in an input stage of the receiver circuit or the transmitter circuit, respectively; a control interface connected with the receiver circuit or the transmitter circuit, respectively, being arranged inside the optical sub-assembly, wherein the control interface is connected to two of the multiple pins of the optical sub-assembly; wherein the optical sub-assembly is configurable through the control interface in order to perform, in the case of the receiver circuit, a bit rate adjustment, a power consumption adjustment, and/or an output signal configuration, and in the case of the transmitter circuit, to perform a bit rate adjustment and/or an output signal configuration.
