Technical Field
The embodiment of the invention relates to the field of transmission and IP (protocol for interconnection between networks), in particular to optical cross-connection equipment of a metropolitan area backbone transport network.
Background
In recent years, with the rapid development of data services, more and more services are directly connected between backbone nodes of a metro backbone transport network through optical fibers.

In the prior art, Optical cables are terminated on an Optical Distribution Frame (ODF) in a backbone node, each terminating end of each Optical fiber in the Optical cable is on a single-core FC/SC type connector port of the ODF, and services are connected to corresponding equipment ports from the ports of the ODF through jumpers.
However, the above-mentioned prior art has the following disadvantages: (1) the equipment capacity is small: the capacity of a common ODF standard frame is generally 576 cores; (2) the number of the jumping fibers is large, and the management is difficult: when the capacity of the ODF exceeds 2/3, the excessive jumpers are messy and difficult to be tidied, so that the connection relation of fiber cores is difficult to manage; (3) lack of effective management of ODF ports: the traditional ODF does not have the function of network management, the service condition of each port of the ODF can be recorded only by hand, and the ODF is difficult to dynamically adjust according to the actual service condition; (4) weak cross ability: when there is a requirement for optical fiber direct connection service between two non-adjacent nodes (such as nodes a and P in fig. 1) in an optical cable ring of a backbone transport network, the service needs to be implemented only by an intermediate node (such as node B or node O in fig. 1) ODF hop; if there is 48 core direct connection services between points a and P, 48 single core hop fibers must be connected through node B or node O.

Further, referring to fig. 5, each subscriber unit 32 is divided into a front portion and a rear portion by a subscriber unit panel 321, the front portion (front side of the rack) is a wire arranging passage 322, and the space of the rear portion (rear side of the rack) contains 2 fiber coiling modules 323;

The direct connection requirement of a large number of fiber cores between any 2 nodes in the optical cable ring can be conveniently realized. (3) The number of the jumping fibers is small, and the management is orderly: the jump fiber in the device of the embodiment is divided into a cross jump fiber and a terminal jump fiber; the cross-hop is a connection hop on intermediate node equipment when an optical fiber direct connection service exists between two nonadjacent nodes in an optical cable ring of a backbone transmission network; terminal jump fiber means the jump fiber of the single core FC/SC adapter 324 connected to the user equipment; because the cross-over fibers are MPO short-over fibers 315, the cross-over fibers do not occupy the jump-fiber storage unit 5 of the rack; the fiber skipping storage unit 5 only needs to store and manage terminal skipping fibers, the number of the terminal skipping fibers is not more than 432 cores at most, the number of the skipping fibers is small, and maintenance and management are convenient. (4) The single-core FC/SC adapter interface 324 provided by the device of this embodiment to the user is an intelligent port, and when a patch cord with an electronic tag is used, intelligent identification and management can be performed on each port.
The optical cross-connection equipment for the metro backbone transport network provided by the embodiment of the invention is mainly used in the metro backbone nodes, and can solve the problems of small equipment capacity, large quantity of jumping fibers in the equipment, weak cross-connection capability of the equipment, lack of effective management on ODF ports and the like of the existing ODF equipment, so that a large number of fiber cores between any metro backbone nodes can be directly connected conveniently.
