System and process for a differential coding in optical information transmission uses a modulo two addition to produce the encoded sending signal

摘要

A system for the differential coding of optically transmitted information from a sender (TX) to a receiver (RX) comprises an encoder (COD) in the sender with a modulo-2-addition producing a transmission signal from the input signal (U) which modulates the optical signal (OS) in the time multiplex plane (TDH).
