Split pigtail connection performance test device

Abstract

The invention discloses a split-type pigtail connection performance test device, which aims to provide a device that can directly detect whether the optical fiber connection is in compliance at the same site when the optical fiber and the flange are connected without changing the connection state of the optical fiber. The required split pigtail connection performance test device. It includes two test boxes. The detection box includes a detection box body; a gland; an optical fiber identification device, the optical fiber identification device includes an installation port arranged on the upper surface of the detection box body, a floating support plate located in the installation port; a connection performance detection device, the connection performance detection device includes a setting An elastic light-shielding pressing block on the lower surface of the pressing cover, a detection groove arranged on the lower surface of the elastic light-shielding pressing block, and a laser module arranged in the detection groove. The laser module in one of the two detection boxes is a laser emitting module, and the laser module in the other detection box is a laser receiving module.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a split-type pigtail connection performance testing device. Background technique [0002] There are many optical distribution units and fiber jumping devices in the optical fiber communication network. During the optical network and detour process, multiple sites need to use pigtails to jump the core of one optical cable line to another line. The fiber jumping operation is an optical fiber Frequently performed work in operation and maintenance operations. At present, most optical distribution racks use standard FC flanges or SC flanges and pigtails for optical connection. The pigtails jump from the core of one optical cable line to another line. Due to the influence of component quality and aging, the fiber core jumper loss of individual sites may be large or even unusable. As the capacity of optical fiber distribution equipment increases, more and more such ...

Problems solved by technology

At present, most optical distribution racks use standard FC flanges or SC flanges and pigtails for optical connection. The pigtails jump from the core of one optical cable line to another line. Due to the influence of component quality and aging, the fiber core jumper loss of individual sites may be large or even unusable. As the capacity of optical fiber distribution equipment increases, more and more such problems will occur, which is not conducive to optical fiber operation and maintenance. The work is carried out smoothly; therefore, after the fiber jumping operation is completed, it is necessary to check whether the fiber connection performance is qualified

[0003] At present, after the fiber jumping operation is completed, the light source optical power meter and OTDR are generally used for testing, and the test is performed by plug-in coupling. Therefore, during the test, only one end of the pigtail and the flange connection can be tested first, and then, Disassemble the flange connection of the pigtail at this end, and then test the reliability of the connection between the pigtail and the flange at the other end, so it can only guarantee the reliability of the connection between the pigtail and the flange at one end, and the optical fiber work site is a closed-loop operation. After the pigtails are connected at both ends, whether the connecting flanges at both ends of the fiber jumper meet the requirements can only be tested by using the light source optical power meter and OTDR test at the opposite end of the optical cable line at the next station, so jumping often occurs at one station. When using OTDR to test the optical paths in both directions successively, they are all good, but when we jump to the next station, the OTDR detects that there is a large loss in the pigtail connection at the previous station, so we have to go back to the previous station to pair the pigtail and the cable. The flange is inspected and replaced. Even new pigtails and flanges have such problems, which will greatly increase the workload of operators and affect the work efficiency of fiber jumper operations.
