Abstract

The optical multiplexer includes two optical flber circulators and one optical fiber circular mirror containing a circular loop comprising two circular arms of the same length with the circular loop being connected to the two optical fiber circulators separately through fiber coupler. There are fiber grating set in the loop and phase regulator in the arm of the loop. The present invention with wide application may be used in the simultaneous upper and lower channel division / insertion multiplex of monowavelentth optical channel, multiwavelentth optical channel, all odd wavelength optical channel and all even wavelength optical channel, and has simple structure and stable performance.

Description

technical field [0001] The invention is a dynamically configurable optical add / drop multiplexer. It is suitable for the add / drop multiplexing of the node configuration optical channel in the field of optical fiber communication. Background technique [0002] With the development of dense wavelength division multiplexing DWDM (Dense Wavelength Division Multiplexing) optical fiber communication technology, the transmission capacity has been greatly improved, the number of network nodes is increasing, and the wavelength division multiplexing network is from point-to-point ) linear structure, developed to multi-node, with optical add / drop multiplexer OADM (Optical Add / Drop Multiplexer), and realize multi-node interconnection, and develop to mesh ring network structure (Mesh). The number of DWDM wavelength channels is increasing day by day. The use of OADM can avoid unnecessary photoelectric-to-electrical-optical conversion, greatly save equipment costs, and speed up operation; ...
