Abstract

The invention discloses a multi-wavelength component for the fiber optic communication. The component is used for multi-wavelength laser coupling for single optical fiber transceiving communication and comprises an emitting portion, a receiving portion, an optical coupling portion and an optical fiber terminal. The optical fiber terminal is provided with a straightening portion used for straightening the laser; the emitting portion comprises more than one emitting terminal comprising laser chips generating laser and straightening lens groups; the wavelengths of laser generated by the laser chips of the emitting terminals are different; the straightening lens groups are located in the light emitting ports of the emitting terminals, and the laser generated by the laser chips is concentrated through the straightening lens groups before emitting to the optical coupling portion through the light emitting ports. An optical path component is optimized, the brightness and parallelism of laser emitted through the emitting portion can be guaranteed well, the optical path component is easy to package and adjust, and the multi-wavelength laser coupling capability of an optical coupling component can be improved.

Description

technical field

[0001] The invention relates to the field of optical fiber communication, in particular to a multi-wavelength component for optical fiber communication. Background technique

[0002] With the application of optical fiber network becoming more and more popular, especially the gradual implementation of fiber access FTTH projects around the world, as well as point-to-point data transmission, in order to make reasonable use of the deployed fiber resources, the market for multi-wavelength laser coupling in a single fiber The demand for single-fiber bidirectional components to realize multi-channel transceiver communication is also increasing. With the advancement of triple play and the continuous promotion of fiber-to-the-home networks, the demand for single-fiber three-way components in the market has increased, especially for single-fiber three-way components with a narrow interval between two wavelengths.

[0003] At present, the single-fiber bidirectional com...
