Optical switch reversing device for test of multiple light jaws equipment

Abstract

The invention relates to a light switcher used to test multi-light-port device, wherein it is arranged between one error bit tester and one tested multi-light-port device; it comprises one main controller and a light switch array unit; said main controller comprises a processor, a communication interface, a driving circuit and a programmable logic unit; the main controller is used to communicate between the light switch and the error bit tester, to arranged the light switch of light switch array unit; said light switch array unit has several light switches, whose setting is controlled by the main processor uses driving circuit to set the control pin of each light switch. The invention can be connected to extender, to improve the testing efficiency, with simple operation and low cost.

Description

technical field [0001] The invention belongs to testing equipment in the field of communication, in particular to an optical switch switching device which can be used for testing optical port error code functions of multi-optical port equipment. Background technique [0002] Due to the large transmission capacity of optical fiber, the optical transport network with optical fiber as the transmission carrier has become one of the basic networks of the entire communication network. At present, a large number of multi-optical port devices are used on the Internet. Typical multi-optical port devices include SDH transmission systems based on time division switching. Equipment and DWDM dense wavelength division system equipment based on wavelength switching. At the same time, for system equipment with optical ports, due to the increase in transmission capacity, there are more and more optical ports at each end of the equipment. In terms of DWDM dense wavelength division system equi...

Problems solved by technology

[0005] 1. If figure 1 As shown in the figure, connect the bit error testing equipment to each optical port separately, and test each optical port separately, so that it can be judged whether each optical port is normal, but since each optical port needs to be tested separately, its efficiency is very low

[0006] 2. If figure 2 As shown, connect the bit error test equipment to the sending and receiving ends of the first and last optical ports, connect the receiving and sending ends of adjacent optical ports with wires, and directly cascade test for multiple optical ports, so that if all optical ports are in good condition , each optical port of the multi-optical port device can be judged to be normal with only one test, but if some optical ports of the multi-optical port device are faulty, the faulty optical port must be located according to the method described in method 1, and the test Efficiency is still difficult to improve
