Description

technical field

[0001] The invention relates to an Ethernet passive optical network optical line terminal (EPON OLT) technology, in particular to a single-fiber four-way high-speed symmetrical rate 10G EPON OLT optical module. Background technique

[0002] With the promotion and popularization of optical fiber access technology (FTTX), high-speed broadband services are gradually changing the way people live and work. Due to the continuous increase of people's demand for bandwidth, the current 1G EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) technology has gradually been unable to meet the growing demand for broadband services. Therefore, the 10G EPON technology that can provide higher bandwidth becomes the solution of the next generation passive broadband access network logically. In EPON technology, the optical transceiver module of OLT (Optical Line Terminal, optical cable terminal equipment, terminal equipment used to connect optical fiber tru...
