Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber testing, and in particular relates to multi-port optical fiber testing equipment and a testing method. Background Art

[0002] Optical power meters and optical multimeters usually have only two ports, one for receiving and one for transmitting. One group of personnel emits light at one port as a light source, while the other group receives light at the other end of the optical cable to test the light continuity and attenuation of the optical path. The red light function of the optical multimeter generally has a small transmission power and is difficult to be recognized by the naked eye over 10 kilometers. The red light emitted is a type of laser. If it is directly irradiated into the eyes, it may cause varying degrees of damage to the eyes.

[0003] In the existing optical fiber testing technology, two groups of people are required to use two devices to illuminate and receive light at both ends of the optical cable. Each time a port is tested, the other end needs to be contacted by phone and the next port is manually changed to test the quality of the optical cable. When an optical fiber line sequence welding error occurs in the optical cable line, the receiving end needs to blindly plug all ports to test the fiber core welding position, which is time-consuming and laborious. Summary of the invention

[0004] The purpose of the present invention is to provide a multi-port optical fiber testing device and a testing method to solve the problems existing in the prior art. The device can test multiple optical fibers at one time, thereby improving the testing efficiency.

[0005] The technical solution of the present invention is:

[0006] A multi-port optical fiber test device comprises a multi-port optical fiber tester, an optical fiber distribution frame for connecting an optical cable and the multi-port optical fiber tester, and an optical fiber jumper module for connecting at the opposite end of the optical cable.

[0007] Specifically, the multi-port optical fiber tester includes a multi-port optical power meter for collecting optical signal strength in real time, a control unit for operating the tester and displaying test results, and multiple optical transmitting ports and multiple optical receiving ports connected thereto.

[0008] Specifically, the fiber jumper module includes a plurality of light emitting ports and a plurality of light receiving ports which are arranged corresponding to the multi-port fiber optic tester.

[0009] Specifically, the optical fiber distribution frame includes a plurality of corresponding ports adapted to the optical transmitting ports and the optical receiving ports of the optical fiber jumper modules.

[0010] Specifically, the light emitting port of the multi-port optical fiber tester is provided with a light source, and the light source is one of a distributed feedback (DFB) laser, a light emitting diode (LED), and a superluminescent diode.

[0011] Specifically, the multi-port optical power meter uses one of a photodiode, a phototransistor, and a photonic integrated circuit (PIC) detector.

[0012] A multi-port optical fiber testing method, using the multi-port optical fiber testing device as claimed in any of the above claims, comprises the following steps:

[0013] S1. Line connection: insert multiple light transmitting ports of the multi-port fiber optic tester into the corresponding ports of the fiber optic distribution frame, insert multiple light receiving ports of the multi-port fiber optic tester into the corresponding ports of the fiber optic distribution frame, and at the other end of the optical cable, insert the fiber optic jumper module into all ports of the fiber optic distribution frame in the order of all ports;

[0014] S2, start the multi-port optical fiber tester;

[0015] S3, the optical transmitting port of the multi-port tester transmits an optical signal, and the optical signal passes through the optical fiber distribution frame, optical cable and optical fiber jumper module and returns to the optical receiving port of the multi-port tester;

[0016] S4. The control unit processes the collected data, calculates the optical attenuation value of each optical fiber and displays it.

[0017] The beneficial effects of the present invention are: having multiple pairs of light emitting ports and light receiving ports, multiple optical fibers can be tested at one time as needed, thereby improving the test efficiency, and using a high-precision optical power meter to ensure the accuracy of the test results.

[0018] It can be operated by touch screen, which is simple and intuitive. Expansion interfaces can be reserved according to actual needs, and it can be upgraded to a fiber optic tester with more ports. It is suitable for fiber optic communication systems, data centers, fiber optic network maintenance and other fields, and is used to quickly detect the quality of fiber optic optical paths and ensure the stable operation of communication systems.

Start the multi-port optical fiber tester, and the light from the light emitting ports of ports 1-6 will be returned to the light receiving ports 7-12 through the optical fiber distribution module at the opposite end. In this way, the optical attenuation of 12 optical fibers can be tested at one time.
