Intelligent Star Coupler

The transmitter and receiver module is a component that is able to convert electrical signals into optical signals and transmit them across the byteflight  fiber-optic bus.

Each satellite has a transmitter and receiver module (S/E module).

Each of the S/E modules is connected via the byteflight  with the Intelligent Star Coupler in the SIM. In the SIM, there is also a transmitter and receiver module for each satellite.
