Abstract: This application provides a signal amplification apparatus, an optical signal receiving apparatus, and a method, to meet high-performance time-division reception of 50GPON and GPON uplink signals, and implement a requirement for coexistence of 50GPON and GPON terminal devices on a same PON interface in a system. The apparatus includes a signal receiving unit, a channel selection unit, a first amplification and data recovery channel, and a second amplification and data recovery channel.
