Description

Optical fiber jumper wire for recognizing photoelectric end head

Technical Field

The utility model belongs to the technical field of optical fiber communication, and particularly relates to an optical fiber jumper for identifying photoelectric ends.

Background

Optical fiber jumpers are important components of optical communication systems, and are devices for detachably connecting optical fibers and devices in the optical communication systems. The optical fiber jumper wire connects the direct transmission of the station to the station, connects the communication between the transmission equipment and the service equipment, completes the information transmission of the line channel, and is a neural network forming an optical communication system.

With the development of information technology and the great demands on data storage and exchange, the demands on large-scale data centers are rapidly increased, whether the large-scale data centers are internet data centers, cloud computing data centers, office data centers or multi-data center interconnection and data center storage networks, with the increase of services, optical fiber jumpers in cabinets are more and more, and are difficult to identify. When the connection port of the optical fiber jumper needs to be adjusted, the other end of the optical fiber jumper is difficult to find out from numerous optical fiber jumpers, so that the problem of technical staff is solved.

Products such as a color pigtail type optical fiber jumper, a pigtail color coding type optical fiber jumper and the like have been developed at present, and input and output ends of the optical fiber jumper are paired by using 12 different colors. However, due to the limited number of colors of the pigtails that can be used, the huge number of fiber optic jumpers in the data center cannot be dealt with. Although the pigtail color coding type optical fiber jumper can generate a large number of jumper wire distinction, the color coding is difficult to distinguish directly and manually, and the paired jumper wire ports are difficult to find in the complicated optical fiber jumper wires. Therefore, these conventional optical fiber jumpers cannot meet the requirements of adjustment and maintenance of the optical communication network in the later stage of the large-scale data center.

Aiming at the defects of the traditional optical fiber jumper, the utility model provides an optical fiber jumper with photoelectric end head identification, and when the optical fiber jumper is detected, the optical fiber jumper can emit light at the other end of the optical fiber jumper after being connected with an external power supply, so that the identification of two end heads of the same optical fiber jumper is realized. The optical fiber jumper wire for identifying the photoelectric end head has the advantages of simple structure, safety, reliability, convenience, rapidness and strong practical value.
