Abstract

The invention discloses a multi-channel optical switching device which comprises an input collimator, an output collimator, a lens seat disc, a swing arm needle, a micro motor and a control circuit board. The micro motor is electrically connected with the control circuit board; when light path switching is carried out, the micro motor is started under the control of the control circuit board, andthe swing arm needle is driven by the micro motor to rotate clockwise or anticlockwise by taking the central hole of the microscope base plate as an axis; and the input collimators on the group of input holes on the lens seat disc are conducted with the output collimators on one group of output holes on the lens seat disc. According to the multi-channel optical switching device, switching of optical paths of the multi-channel optical switching device can be achieved in a mechanical control mode, the multi-channel optical switching device has the advantages of being low in insertion loss, largein channel number, high in isolation degree, free of light in wavelength and polarization and the like, the size and complexity of the multi-channel optical switching device can be reduced, the production cost is reduced, and troubleshooting is easier.

Description

technical field [0001] The invention relates to the technical field of optical signal switching, in particular to a multi-channel optical switching device. Background technique [0002] As a key component of all-optical networks, multi-channel optical switching devices are widely used in the fields of all-optical routing, multi-channel monitoring, device testing, optical network cross-links, and self-healing protection. On-off and switching control of each optical path. When the existing optical switching device switches multiple optical paths, for each optical path, its common practice is to set 1×N light beams between the input single-core collimator and the output single-core collimator of the optical path. switch, and control N 1×N optical switches through a single-chip microcomputer control circuit, and then achieve the purpose of controlling the on-off and switching of multiple optical paths. However, with the development of optical communication transmission network...
