Installation structure of multi-core optical fiber array

Abstract

The invention discloses a mounting structure of a multi-core optical fiber array. The structure comprises a V-shaped groove, multi-core optical fibers arranged in the V-shaped groove, and a cover plate covering the opening of the V-shaped groove. The multi-core optical fibers are simultaneously pressed on the inner walls of both sides of the V-shaped groove through the cover plate. The opening angle of the V-shaped groove is 100 degrees to 120 degrees, and the optical fiber misalignment angle is 0.7 to 0.8 degree. The V-shaped groove is used to position the multi-core optical fibers to providecertain motion allowance for the multi-core optical fibers, and then the positions of the multi-core optical fibers in the V-shaped groove are adjusted through the cover plate. The cover plate can determine the limit adjustment position of the multi-core optical fibers in the V-shaped groove through the opening angle of the V-groove. In order to reduce the optical fiber misalignment angle as muchas possible, the opening angle of the V-groove needs to be as large as possible to increase the rotational allowance of the multi-core optical fibers, and the level of the multi-core optical fibers is controlled through the cover plate as much as possible. Both sides of the multi-core optical fibers are firmly pressed on the inner walls of both sides of the V-shaped groove at the same time, so asto ensure the positioning effect of the inner walls of the V-shaped groove on the multi-core optical fibers.

Description

【Technical field】 [0001] The invention relates to an installation structure of a multi-core optical fiber array, and belongs to the field of optical fibers. 【Background technique】 [0002] The traffic of the current optical fiber communication network is growing at a high rate of 20%-60%. The port rate of the optical communication system has reached 100Gb / s, and the system capacity has reached 10Tb / s. In the next ten years, the capacity of the optical fiber communication system will reach about 100Tb / s. However, there are several limitations in the current optical fiber communication system: first, combined with the low-loss transmission window and amplifier bandwidth, the useful spectral efficiency is only about 10 THz; The deterioration of the optical signal-to-noise ratio and the nonlinear damage caused by the nonlinear Kerr effect of the fiber make the system capacity have a nonlinear Shannon limit, that is, improving the transmission quality of high spectral efficiency...
