    The SPIE Digital Library offers a comprehensive range of content on receivers, encompassing various aspects of their design, function, and application across multiple fields, particularly in optics and photonics. The library includes research articles, conference proceedings, and technical papers. To overcome this challenge, we have proposed and experimentally demonstrated a receiver with shared-complexity between optical and digital domains that enables 80 km transmission reach below KP4 FEC limit for a 32 GBd on-off keying signal. The primary function of an optical receiver in an optical fiber communication link is to convert the received. The design of an optical receiver can be quite sophisticated because the receiver must be able to detect weak, distorted signals and make decisions on what type of data was sent based on an amplified and reshaped version of this distorted signal.
