Abstract

The invention discloses a stable and adjustable CWDM small module. The stable and adjustable CWDM small module comprises a wave division module; the wave division module is provided with a module input end and a module output end, the module input end and the module output end form an optical fiber array, and the optical fiber array comprises an input optical fiber and a plurality of output optical fibers. The beneficial effects of the invention are that the device achieves the continuous adjustment of the lateral position of a light focusing point through the continuous adjustment of the lateral position of the auxiliary lens, achieves the high-efficiency coupling of an optical signal into an optical fiber, and can enable a laser signal to be coupled into a single-mode optical fiber in astable, efficient, quick and reliable manner.

Description

technical field [0001] The invention relates to a CWDM module, in particular to a stable and adjustable small CWDM module, which belongs to the technical field of optical signal transmission. Background technique [0002] The traditional passive CWDM module is formed by cascading three-port devices, which has the disadvantages of large volume and large insertion loss. However, for the improved CWDM module design of the existing three-port device cascading, the optical signal is transmitted by the input optical fiber (commonly called the COM end) Enter, use an input collimator to collimate the output light of the input fiber and enter the first filter; the optical signal passes through the first filter and is coupled to the first output fiber through the first output collimator In the middle, the optical signal is separated; the remaining optical signals are reflected by the first filter to the next filter for similar optical signal separation; and so on, until the signals of...
