Abstract

The invention relates to an optical channel property on-line detecting module, which comprises: an input optical fiber which is a standard single-mode optical fiber; a base which is a rectangle plate; a collimation lens with an interface of optical fiber input while said input optical fiber is connected to said optical fiber input interface and said collimation lens is fixed at one side of base; a grating table which is trapeziform and its middle has one rectangle groove; said grating table is fixed on the base at one end of collimation lens; a diaphragm whose two surface form right angle while its has a light inlet and a light outlet; said diaphragm is fixed at the outer side of groove of grating table; a solid holographic grating fixed inside the groove of grating table; a light receive interface fixed on the base at one side of collimation lens; a photodetection detecting array fixed at the end of light receive interface; and a top cover which is a rectangle frame covering the base and fixed on the base.

Description

Technical field [0001] The invention is an on-line monitoring instrument for optical channel performance in an optical communication network, is a key component of an intelligent optical network, and is also widely used in the field of spectrum analysis. Background technique [0002] With the widespread application of DWDM optical networks, the operating conditions of the DWDM system can be monitored effectively and in real time, so as to obtain the wavelength drift, power fluctuation, signal-to-noise ratio of each channel and other information that may cause data errors and transmission failures. It has gradually become an indispensable part in the construction of intelligent optical networks. The traditional optical network detector only detects the total optical power of all channels, and cannot monitor the operating conditions of each channel in the DWDM system and the amplifiers, multiplexers, optical switches, optical fibers themselves and optical fiber connections in the s...
