Abstract

A node equipment port expansion system based on optical fiber interconnection belongs to the node equipment field in a data network. The node equipment port expansion system based on optical fiber interconnection comprises a plurality of link data processing units, a link converging / decomposing unit and a converting unit. The plurality of link data processing units are converged at the link converging / decomposing unit. The link converging / decomposing unit and the converting unit are converged. The node equipment port expansion system and the node equipment port expansion method have advantages of effectively reducing number of interconnected cables in node equipment port expansion, increasing bus transmission distance, reducing system expansion cost, reducing the number of network data forwarding layers, satisfying a requirement for in-time processing and transmitting high data volume in a network system, facilitating construction of the network system based on SpaceWire node equipment, improving stability and data transmission efficiency of the network system, and realizing optical fiber interconnection of the system.

Description

technical field [0001] The invention relates to node equipment in a data network, in particular to a node equipment port expansion system and method based on optical fiber interconnection. Background technique [0002] SpaceWire is a high-speed, point-to-point, full-duplex serial bus based on two commercial standards, IEEE 1355-1995 and LVDS (Low Voltage Differential Signaling), and has the characteristics of low cost, high reliability and flexible structure.
