A multi-channel combined wave switching device for simulating and monitoring the pon system

Abstract

The invention discloses a multichannel combined wave switching device used for a simulation monitoring PON system. The multichannel combined wave switching device used for the simulation monitoring PON system comprises an A type wavelength division multiplexer (1), a 1*2 optical switch (4), a 2*N optical switch array (2), and a B type wavelength division multiplexer array (3). A combined wave port of the A type wavelength division multiplexer is connected with a common port of the 2*N optical switch array (2), and a common port of the 1*2 optical switch (4) is connected with the other common port of the 2*N optical switch array (2). The A type wavelength division multiplexer (1) is a three-port wavelength division multiplexer. The B type wavelength division multiplexer array (3) is an array composed of multiple four-port wavelength division multiplexers. The signals separated to each port are used for simulation monitoring of a PON transmission link. The B type wavelength division multiplexer array (3) is connected with selection ports of the 2*N optical switch array (2), and the number of the ports of the B type wavelength division multiplexer array (3) is the same as that of the ports of the 2*N optical switch array (2). According to the multichannel combined wave switching device used for the simulation monitoring PON system, concentrated monitoring simulation is achieved.

Description

technical field [0001] The invention belongs to the field of optical communication, and relates to a multi-channel multiplexer switching device, in particular to a multi-channel multiplexer switcher for online simulation monitoring of a PON (Passive Optical Network, Passive Optical Network) system. Background technique [0002] With the further commercialization of fiber-to-the-home (FTTH), the number of laid optical fibers is increasing, the coverage area is getting wider and wider, and the traffic carried by optical fiber cables is also increasing. Once a failure occurs, it will cause serious damage to the entire communication network. Great loss. Passive Optical Network (PON) has become the main realization technology of FTTH due to its advantages of high bandwidth, multi-service access, saving fiber and easy maintenance. The optical distribution network (ODN) of PON is composed of passive components. Optical splitters, optical connectors and optical cables are placed ou...
