Abstract
Systems and techniques for are described herein. An optical signal is received and the optical signal is converted into an electrical signal. The electrical signal is amplified through a trans-impedance amplifier to produce an amplified signal. The amplified signal is normalized using a limit amplifier to generate a normalized signal. Bit values are determined from the normalized signal and a corresponding probability bit is generated for each bit value using a threshold detector. The bit values and the corresponding probability bit are encoded into a four-level pulse-amplitude modulation (PAM-) signal. The PAM-signal is transmitted to an application-specific integrated circuit (ASIC) for data recovery and error correction processing.
