Abstract

The invention relates to an optical fiber array and a manufacturing method thereof. The optical fiber array comprises a base, a cover plate, a set of optical fibers, a solder layer and curing glue, one end of the base is higher than the other end to form a step, multiple V-shaped grooves are formed in the upper surface of the higher end of the base, and one end of each optical fiber is stripped from a coating layer and a cladding is exposed; the ends, exposed out of the cladding, of the optical fibers are arranged in the V-shaped grooves in a one-to-one correspondence mode, the cover plate covers the base, the solder layer is located between the upper surface of the base and the cover plate, and the base and the cover plate are fixed so that one ends of the optical fibers can be fixed in the V-shaped grooves, and the other ends of the optical fibers can be located at the lower end of the base. The curing adhesive fixes the other ends of the optical fibers at the lower end of the base.According to the optical fiber array, the stability of the optical fibers is guaranteed, the reliability of the whole optical fiber array is improved, the situation that the stability of the optical fibers is affected due to looseness or dislocation of optical fiber fixation caused by temperature rise during work is avoided, and the optical fiber array is simple in structure, low in manufacturingcost and convenient to apply and popularize on a large scale.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to an optical fiber array and a manufacturing method thereof. Background technique [0002] With the rapid development of technologies such as big data and 5G, optical fiber arrays have been widely used in optoelectronic modules, wavelength division multiplexing systems, wavelength selective switches and other products. The traditional optical fiber array positioning components are made of glass and bonded with UV-cured glue, which has the following problems in the production and practical process: poor reliability. Since the photoelectric module usually generates heat during operation, the temperature of the optical module rises. After a temperature cycle or a high-temperature and high-humidity environment, the glue may crack or degumming the positioning components, resulting in problems with the product that cannot be used normally and reliably. Work. Contents of the inv...
