Abstract

The invention relates to a ferrule adapter for inhibiting chromatic dispersion in the process of optical fiber conduction, comprising a tail jacket (10), a ceramic sleeve (40) and an incident single-mode ceramic ferrule (61). An intermediate single-mode ceramic ferrule (60) is embedded into the ceramic sleeve (40); both ends of the intermediate single-mode ceramic ferrule (60), the incident single-mode ceramic ferrule and the inserting end of an emergent single-mode ceramic ferrule are all ground into a regular spherical shape with raised intermediate fiber cores; the three optical fibers keep the state of fiber core contact and air isolation of peripheral coverings; and a covering film is consumed by air isolation. The invention can well ensure the concentration ratio of luminous flux inmultimode optical fibers, the incident angle of light coupled into the multimode optical fibers is single and basically a low-order mode and a basic mode, the harm of the chromatic dispersion betweenmodes can be basically minimized, and the cost is lower. In addition, the invention can be realized based on the traditional ferrule adapter, facilitate the modification and avoid the waste.

Description

technical field [0001] The invention relates to the field of optics, in particular to a method for suppressing dispersion during light transmission, a special adapter and an assembly method thereof. Background technique [0002] With the development of optical communication technology, the requirements for transmission rate are getting higher and higher, and the technology above 10G is becoming more and more mature and popular. For cost considerations, many basic networks still use the original multi-mode optical fiber transmission network, of course to reduce costs. At the same time, it also introduces a new problem, that is, because the optical fiber digital communication transmits a series of pulse codes, the pulse broadening of the optical fiber during transmission leads to the phenomenon of overlapping pulses, that is, inter-symbol interference, thus Errors in the transmission code are formed, resulting in errors. In order to avoid bit errors, it is necessary to length...
