Abstract

The invention discloses a multi-channel intelligent optical testing device which comprises a light source, a light source control circuit, a wavelength calibration monitoring module and an optical switch which are sequentially connected. One output end of the optical switch is sequentially connected with a polarization controller, a 2*2 shunt and a 1*N optical splitter. One output end of the 2*2 shunt is connected with a first optical power detector, and one input end of the 2*2 shunt is connected with a second optical power detector. The other output end of the optical switch is connected with an N*N shunt, and output ends of the N*N shunt are connected with array optical power detectors in a one-to-one correspondence mode. The light source control circuit, the wavelength calibration monitoring module, the optical switch, the polarization controller, the first optical power detector, the second optical power detector and the array optical power detectors are connected with a control unit. The testing device can test optical indexes of a multi-channel module.

Description

[0001] technical field [0002] The invention relates to a testing device, in particular to a multi-channel intelligent testing device for optical index testing and verification of optical communication device modules, and the invention belongs to the communication field. [0003] Background technique [0004] In order to meet the demand for bandwidth and transmission rate, communication operators and system suppliers combine DWDM Dense Wavelength Division Multiplexing technology as the main means of current optical fiber communication. With the continuous upgrading of DWDM technology, optical fiber The wide use of communication networks makes the network topology more and more complex, and there are more and more devices and modules with different functions, such as dynamic channel equalizer (DGE Dynamic Gain Equaliztioner), adjustable power optical multiplexer (VMUX Variable Multiplexer) , Optical Add-Drop Multiplexer (OADM Optical Add-Drop Multiplexer), Attenuator (VOA v...
