Abstract

The invention belongs to the field of optical switches, and relates to an electric mechanical type optical switch for overcoming various defects existing in an existing optical switch. The optical switch comprises a box and a box cover. The box is provided with an optical fiber access port and a multi-optical fiber array optical fiber output port. The box is internally provided with an adjusting device switching an optical path. The adjusting device comprises a motor, a U-shaped block, a guide rail, a sliding block, a lead screw and a photoelectric sensor. The bottom of the U-shaped block is installed at the bottom in the box, the motor is installed at one side of the U-shaped block, the output end of the motor is connected with the lead screw and drives the lead screw to rotate, the sliding block is arranged on the guide rail, the lead screw penetrates through the sliding block, the sliding block is provided with an optical fiber fixing support used for fixing a single optical fiber array, and the optical fiber fixing support is provided with the single optical fiber array. The motor servo controls the parallel movement of the input light, an input lens optical fiber is shifted through the rotation of the motor servo, and therefore the optical path switching is achieved. Thus, the optical switch is simple in structure, low in cost, reliable in performance and easy to achieve.

Description

technical field [0001] The invention belongs to the field of optical switches, in particular to an optical switch in which a single optical fiber is connected to a plurality of optical fiber arrays. Background technique [0002] With the rapid development of communication and information network technology, people have higher and higher requirements for capacity, communication speed, etc., and traditional electronic communication has been difficult to meet the requirements. A brand-new optical fiber communication technology emerging at present—optical crossover interconnection technology will fundamentally solve the electronic bottleneck problem, thereby realizing all-optical communication. Optical switches are key components in optical cross-connect and dense wavelength division multiplexing (DWDM) systems. The optical switch cooperates with the dense wavelength division multiplexer to realize free routing of each wavelength and realize all-optical switching. In recen...
