Embodiment 1

[0061] Such as Figure 2~4 As shown, the first multi-functional optical fiber adapter provided in this embodiment includes an optical component accommodation cavity 10, an adapter input end 20, an adapter output end 30 and an optical component 500 with an optical signal processing function; the optical component accommodation cavity 10 is disposed between the adapter input end 20 and the adapter output end 30 , and the optical assembly 500 is disposed in the optical assembly accommodation cavity 10 .

[0062] Such as Figure 2~4 As shown, in the specific structure of the optical fiber adapter, the optical component 500, the outline of the optical component receiving cavity 10, the adapter input end 20 and the adapter output end 30 are all necessary for the optical fiber adapter The optical component 500 is used to realize various processing functions (such as realizing optical signal amplification, optical signal attenuation, optical signal unidirectional isolation, optical s...

Embodiment 2

[0072] Such as Figure 5-6 As shown, on the basis of the technical solution of Embodiment 1, this embodiment provides another optical fiber adapter with a simplified structure, which defaults to the setting of the input port structural support 22 and the output port structural support 32, but adds The input-end ribbed structural support 23 integrally formed with the input-end alignment holder 21 and / or the output-end ribbed structural support 33 integrally formed with the output-end alignment holder 31, wherein the The ribbed structural support member 23 at the input end is arranged around the outer periphery of the collimation holder 21 at the input end, and the ribbed structural support member 33 at the output end is arranged around the outer periphery of the collimation holder 31 at the output end. Such as Figure 5-6 As shown, by simultaneously setting the ribbed structural support member 23 at the input end and the ribbed structural support member 33 at the output end, t...

Embodiment 3

[0075] Such as Figure 7 As shown, this embodiment provides another fiber optic adapter based on the technical solution of Embodiment 1, which is different from the fiber optic adapter in Embodiment 1 in that: the optical component 500 has It is an isolator assembly with isolation function and includes a pair of input collimation ferrules and collimation sleeves and a pair of output collimation ferrules and collimation sleeves. The fiber optic adapter includes an adapter input 20 and an adapter output end 30. Such as Figure 7 As shown, the core to realize the unidirectional isolation function of optical signals is the existing optical function core 503, and the input collimation ferrule and collimation sleeve are specifically a pair of input collimation ferrule 502 and input collimation ferrule. The straight sleeve 501 is installed in the adapter input end 20 in a one-to-one correspondence; the output collimation ferrule and the collimation sleeve are specifically a pair of...

Abstract

The invention relates to the technical field of optical fiber communication. The invention discloses a multifunctional optical fiber adapter. An optical assembly accommodating cavity is arranged between an adapter input end and an adapter output end, and an optical assembly with an optical signal processing function is arranged in the optical assembly accommodating cavity. An optical signal processing function module can be integrated in the adapter, so that a plurality of existing optical fiber adapters do not need to be arranged like an existing function processing link, the function processing link in which the optical fiber adapter is used for a single optical fiber to a single optical fiber or used for a single optical fiber to a plurality of optical fibers can be greatly simplified,nodes through which optical signals pass are effectively reduced, the optical power loss is reduced, the number of devices is reduced, and the device cost of the whole link is reduced. In addition, the optical fiber adapter also has the advantages of compact structure, convenience in assembly, strong practicability, simple structure and the like, and is convenient for actual popularization and application.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a multifunctional optical fiber adapter. Background technique [0002] Existing optical fiber adapters (such as LC-type optical fiber adapters) are mainly used in the occasions where two optical fiber connectors are connected, such as Figure 1A As shown, the fiber optic adapter provides mating alignment and reliable fixed mating function for two mated fiber optic connectors. However, in other occasions, during the transmission of optical signals in the optical network, optical modules with special functions are usually required for processing, and then the optical signals processed by the special function modules re-enter the optical network for transmission. [0003] Such as Figure 1B As shown, in order to realize the functional processing of a single fiber to a single fiber (such as optical signal amplification, optical signal attenuation, and one-way iso...
