Description
Technical Field
The invention relates to the technical field of communication, in particular to a detection device for extracting optical signals, an SC optical fiber adapter and an FC optical fiber adapter.
Background
At present, the management of optical fiber jumping points of optical equipment, optical cables, service links and the like of each hierarchy of an optical fiber communication network is generally realized by adopting labels, such as paper labels, electronic labels and photon labels. The paper label is a method widely adopted at present, is simple and low in cost, but cannot realize intelligent management; the optical fiber distribution box is managed through the paper label, after a long time, characters on the paper label can fade and cannot be seen, particularly, the outdoor optical fiber distribution box is harsh in environment, and the characters on the paper label can disappear easily. Electronic tags implement active or passive management based on RF, etc., but are susceptible to electromagnetic interference. Photon labels are proposed methods, such as fiber grating, visible red light and the like, and the fiber grating type is high in cost and not beneficial to large-scale popularization; the visible red light can be observed by naked eyes, and the intellectualization can not be realized. Thereby causing optical interconnect port management failures.
The electronic label technology is used for managing the electronic label of the optical fiber, and the method is that an electronic label reader-writer is embedded in optical fiber distribution panels of optical equipment, optical cables, service links and the like of each hierarchy of an optical fiber communication network, and an electronic label ring is sleeved on an optical fiber jumper so as to realize the identification of the optical cable. The technology needs to pair the electronic tag ring on the optical fiber jumper wire and the electronic tag reader-writer embedded in the wiring board and cannot be separated, otherwise, the technology fails to be effectively managed. In addition, since the electronic tag has to be connected to the commercial power, the electronic tag is susceptible to electromagnetic interference, which affects the use of the electronic tag. In addition, the electronic tag must be manually searched by a fiber sequence searching instrument in a machine room route, and the functions of fault diagnosis, positioning and searching cannot be realized.
In patent No. ZL200910002203.3, a superstructure fiber bragg grating, a heating module, a temperature sensor, and a temperature controller are provided in an optical fiber network, and the reflection wavelength is changed by changing the temperature, thereby realizing the identification of the optical fiber. Firstly, the temperature needs to be strictly controlled, and the method cannot be applied outdoors; in addition, the overall structure size is too large to be used for the optical end interface position; and the cost is high.
The above two methods have the disadvantages more than the advantages, and are not suitable for the full-route dynamic management of optical fiber main distribution frames, optical switch boxes, optical fiber distribution boxes and other facilities, optical cables, optical fiber physical links and service links for bearing services in each level of the optical fiber communication network. The port light taking is realized by adding a small structure at an optical interconnection port, the telecommunication office end introduces a special test signal with the wavelength of 1620nm-1660nm, the optical interconnection port structure detects the test signal, and the communication is subjected to the operations of detection, amplification, coding and the like and then is transmitted back to the telecommunication office end, thereby realizing the intelligent dynamic management of the optical fiber communication network full-route interconnection port.
In the inventions disclosed in patent nos. 201820969207.3 and 201820968101.1, a small section of optical fiber is added to the adapters of two optical fiber ports, so that very weak signal leakage occurs when the optical fibers are butted, and the signal is detected, thereby extracting the optical signal. The optical fibers are directly butted, the leaked light is only about 0.02dB, and the signal can be absorbed and cannot be detected due to the fact that air and the like exist in the butting interface.
In the invention disclosed in patent No. 201820815053.2, a small bent optical fiber is added to the adapter of the two optical fiber ports, and the light leakage is caused by the bending of the optical fiber, so that the detection is performed. The bending radius is too large, and the structure size is too large; the bending radius is too small, the optical fiber transmission loss is sharply increased, and the practicability is not high.
In view of the above problems, the applicant has proposed an application of the chinese patent with application number "201910801623.1" and name "optical signal extraction device and method", and the optical signal extraction device can implement fault self-diagnosis and search and establishment of routing internet by means of photonic label optical signal calibration and analysis, thereby implementing intelligent management of optical fiber full link. In the implementation process of the method, no optical signal is transmitted in the optical fiber in two directions, when the light passes through the light-taking V-shaped or U-shaped notch in two directions, the angle between the extracted light and the axial direction of the optical fiber is 15-25 degrees, as shown in 12, the structure and the installation and the positioning of the optical detector are required, otherwise, the light can enter from one direction to be detected, and can not enter from the other direction to be detected. In addition, how to output the extracted optical signal and conveniently connect with an external management system has not been realized.
