How Do I Detect If A Fiber Optic Patch Cord Is Qualified?
Jun 07, 2017

There are three types of Fiber Optic Patch Cord types: ST-ST, SC-SC, ST-SC. According to the type of fiber, there are two kinds of single-mode fiber and multi-mode fiber. Jumper length specifications are 0.5m, 1m, 2m, 3m, 5m, 10m and so on. According to the cable jacket material can be divided into ordinary type, ordinary flame retardant, low smoke and halogen-free type (LZSH), low smoke halogen-free flame retardant and so on.

According to the building fire rating and fire resistance requirements of the material, integrated wiring system should take appropriate measures. In the flammable area and the building shaft laying cables or cables, should be used for flame-retardant cables and cables; in large public places should adopt flame retardant, low smoke, low toxicity of cable or cable; adjacent equipment or inter- Should use flame retardant wiring equipment.

With the insertion loss meter first with a light pen to determine whether the jumper light to determine the optical fiber failure to determine the indicators of the general carrier-class indicators: insertion loss is less than 0.3dB return loss greater than 45dB.

Fiber Optic Patch Cord performance detection is divided into:

1. Optical performance testing, including return loss / insertion loss test. The test instrument can use the FibKey 7602 return loss / insertion loss tester.

2. End surface geometry test, the test parameters include the radius of curvature, vertex offset, fiber height and so on. The test instrument is an interferometer, and many people use the NorlandAC / NC3000 or CC6000 for testing. In particular, CC6000 interferometer because of cost-effective superior, more and more factories use the instrument.

3. Fiber end scratches detection, using video fiber magnifying glass to observe, such as many factories using FibView FV-400PA to check. The instrument gives the clearest image and the operation is extremely simple. There are customers using FibKey-5600 variable magnification magnifying glass for testing, the instrument set 400 times, 200 times, 80 times magnifying glass in one, can be clearly and easily observe the end of the fiber and the end of the situation. Of course, you can also use the relevant software for automatic inspection.

4. Fiber Rally test, you need to test the fiber connector can withstand the size of the tension.

5. Ambient temperature experiments, the need to test the performance of fiber optic connectors in different ambient temperature conditions.
