Abstract

The invention relates to one fiber interface network without source and its data transmission terminal three in one card, wherein, it sets one hardware network system connected to computer through PCI interface based on one PON system light network unit composed of light network unit and its outside circuit; light network unit and its out circuit is connected to interface fiber through fiber receiver and with other end connected to computer PCI interface through Ethernet MAC controller.

Description

technical field [0001] The invention relates to the fields of optical fiber communication and computer network communication, in particular to a triple-network-in-one network 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...
