Abstract

The invention provides a compatible multi-core optical fiber coupling device, which includes a multi-core optical fiber and an optical fiber bundle. A coupling connection column is arranged between the multi-core optical fiber and the optical fiber bundle. The coupling connection column includes a plurality of distribution areas, and each distribution area is used for matching For different multi-core optical fibers, the distribution area includes a plurality of through holes, and the distribution of the through holes in each distribution area is different. A single-mode optical fiber is arranged in the bundle, and the single-mode optical fiber passes through the through hole to contact the end of the multi-core optical fiber core, which solves the problem that the same coupling device is difficult to be used for connecting multiple multi-core optical fibers and single-mode optical fibers.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a compatible multi-core optical fiber coupling device and a coupling method thereof. Background technique [0002] Multi-core fiber can be simply defined as the existence of multiple cores in a common cladding region. Since the channel capacity of single-mode fiber has increased to 100Tbit / s, it is close to the limit. Multi-core fiber provides the possibility to increase the capacity of fiber communication. However, the currently used communication equipment is output by single-mode optical fiber. If it is necessary to fully integrate multi-core optical fiber communication into the communication system, it is required to achieve low-loss connection between multi-core optical fiber and single-mode optical fiber. Therefore, multi-core optical fiber coupling technology It is particularly important, and it is a key factor to promote the practical application of multi-core o...
