Description

technical field [0001] The invention relates to the fields of optical fiber communication and computer network communication, in particular to a computer Ethernet card used for a passive optical fiber access network and a data transmission terminal thereof. Background technique [0002] Passive Optical Network (PON) realizes the access of comprehensive services on the topology of point-to-multipoint optical network, and mainly completes the access work of multiple services between users and convergence network or wide area network. Typically, a PON system configuration consists of an optical line terminal (OLT) and an optical network unit (ONU), and a passive optical distribution network (ODN) between the OLT and the ONU. The business mode of the existing application mainly provides the access work of various services in the optical network unit (ONU). Due to the diversification and complexity of business types on the access side, high requirements are placed on the optical...
