The invention concerns an optical sub-assembly. Multiple pins extend from the outside to the inside of optical sub-assembly. A light receiver (PD) or a light transmitter (VCSEL) is arranged inside the optical sub-assembly. A receiver circuit (RX) respectively a transmitter circuit (TX) is arranged inside the optical sub-assembly and connected between the multiple pins and the light receiver (PD) respectively the light transmitter (VCSEL), wherein the receiver circuit comprises a receiver communication interface (AP, AN) in order to transform an output signal of the light receiver (PD) into a communication signal, and wherein the transmitter circuit comprises a transmitter communication interface (ZP, ZN) in order to transform a communication signal into an input signal of the light transmitter (VCSEL). A control interface (SCL, SDA) connected with the receiver circuit (RX) respectively the transmitter circuit (TX) is arranged inside the optical sub-assembly, wherein the control interface (SCL, SDA) is connectable to two of the multiple pins. |
