Cross-coupling connector of multi-wavelength encoded optical switch and interval ring optical fibre

Abstract

Multiple optical fibres are divided into n individual optical channels. After passing through collimator, an optical cross distributor with ring shape is formed. Said n individual optical channels are sequentially arranged at external side of disk on rotary axle. The single-mode optical fibres are arranged on said disk and addressed by high-speed deflection driven by coaxial small-inertia deflecting axle. After it is aligned with collimator, a space-division cross connector is formed. Said optical coupling switch is formed by the small gaps between coaxial rings. Said encode switch is a partition encoded full-reflection medium membrane driven by a coaxial rotor of optical scanner.

Description

technical field [0001] A multi-wavelength coded optical switch and an annular gap optical fiber cross-coupling connector, belonging to optical fiber communication [0002] technology field. Background technique [0003] In terms of information technology, more and more information shows that after the Internet, one of the largest industries in information is photonics, which uses optical methods to carry out the Internet, with fast speed and large capacity, and replaces routers in the switching network with optical fiber devices. It can realize all-optical network interconnection, but at present, the replacement of routers in the switching network with optical devices still has the disadvantage of the so-called "electronic bottleneck", that is, the cross-connector of the digital synchronous switch needs to demodulate the electrical signal from the optical carrier, and then After the electronic cross-connection, re-realize the optical / electrical conversio...

[0003] In terms of information technology, more and more information shows that after the Internet, one of the largest industries in information is photonics, which uses optical methods to carry out the Internet, with fast speed and large capacity, and replaces routers in the switching network with optical fiber devices. It can realize all-optical network interconnection, but at present, the replacement of routers in the switching network with optical devices still has the disadvantage of the so-called "electronic bottleneck", that is, the cross-connector of the digital synchronous switch needs to demodulate the electrical signal from the optical carrier, and then After the electronic cross-connection, re-realize the optical / electrical conversion and enter the optical transmission network, not only the equipment is complex, the transmission speed is slow, and the loss is large
