There have been multiple variants of the electrical interface of optical modules that have been used over the years. The earliest forms of optical modules had an analog NRZ electrical interface. In the transmit direction, the optical module would directly drive the laser or LED with the analog signal coming from the front system card. In the receive direction, the module would directly drive the receive electrical interface with the o
