Operating method of optical path interface switchover mechanism for fiber channel test

Abstract

The invention relates to an operating method of an optical path interface switchover mechanism for a fiber channel test. The power supply end of a control module of the optical path interface switchover mechanism is connected with a control power supply, the input end of the control module is connected with a button diverter switch, and the output end of the control module is connected with a drive module. An optical path switchover module comprises two optomagnetic switches, four fiber sending interfaces and four fiber receiving interfaces. The output end of the drive module is respectively connected with the control ends of the two optomagnetic switches, two input ends and two output ends of the first optomagnetic switches are connected with the corresponding fiber sending interfaces and the corresponding fiber receiving interfaces respectively, the control module provides control signals corresponding to the conducted optical path switchover module, the optical path switchover module is connected with a relay protection device, an optical power meter or an optical attenuator through the optical path interface switchover mechanism, then the optical path switchover module is driven by the drive module to carry out multi-interface optical path switching, and therefore the optical path interface switchover mechanism can be in a normal operating state and in a test state of a protection test and the fiber channel test.

Problems solved by technology

The protection of 220kV and above fiber optic channels requires frequent installation and removal of the optical cable connector from the relay protection device during the protection verification test and measurement of optical power, so it is easy to cause the wear of the optical cable interface and the increase in the attenuation of the optical interface contact surface , thereby affecting the accuracy of the relay protection device calibration, and even damage to the optical cable interface will bring hidden dangers to the safe and reliable operation of the main protection of the power line

[0004] At present, the optical fiber protection devices at home and abroad do not have a standard and perfect verification process for the verification of the protection device in the field, especially the verification of the fiber channel.
