Structure:

Fiber optic jumper (also known as fiber optic connector) refers to the cable both ends of the connector plug, used to achieve optical road active connection; A plug at one end is called a tail fiber. Fiber optic jumper OpticalFiberPatchCord/Cable and coaxial Cable are similar, but no mesh shielding layer. The center is the glass core through which light travels. In a multimode fiber, the diameter of the core is 50 cm to 65 cm, roughly the thickness of a human hair. The diameter of single-mode fiber core is 8 m~10 m. The core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber inside the core. On the outside is a thin plastic covering to protect the envelope.

Features:

1. Low insertion loss

2. Good repeatability

3. High return loss

4. Good interpenetration performance

5. Good temperature stability

6. Strong tensile property

Application:

Fiber optic jumper products are widely used in: communication room, fiber to home, local area network, fiber optic sensor, fiber optic communication system, fiber optic connection transmission equipment, national defense combat readiness, etc. Suitable for cable television network, telecommunication network, computer fiber network and optical testing equipment. The subdivision is mainly applied in several aspects.

1. Fiber optic communication system

2. Optical fiber access network

3. Fiber optic data transmission

4. Optical fiber CATV

5. Local area network (LAN)

6. Test equipment

7. Fiber optic sensor

Guidelines for selection:

Fiber optic jumper can be divided into three types according to the types of end: st-st, sc-sc and st-sc. According to the types of fiber, there are mainly single-mode fiber and multi-mode fiber. The length of jumper has the following specifications: 0.5m, 1m, 2m, 3m, 5m, 10m, etc. According to the cable sheath material can be divided into ordinary type, ordinary flame retardant type, low smoke halogen free type (LZSH), low smoke halogen free flame retardant type.

According to the fire rating of buildings and the fire resistance requirements of materials, the integrated wiring system should take corresponding measures. Laying cables or fiber-optic cables in flammable areas and in vertical shafts of buildings shall use flame-retardant cables and fiber-optic cables; Flame retardant, low smoke, low toxicity cable or cable should be used in large public places; Flame retardant wiring equipment shall be used between adjacent equipment and connecting equipment.

How to detect:

The insertion loss meter is used to measure whether the jumper is optical transmission and determine whether the fiber is not broken. The general index of telecommunication level is: insertion loss is less than 0.3db and return loss is greater than 45dB.

Performance detection of fiber optic jumper is divided into:

1. Optical performance test, including back loss/insertion loss test. The test instrument can use the FibKey7602 back/insert loss integration tester.

2. End surface geometry test, including curvature radius, vertex offset, fiber height, etc. The instruments tested were interferometers, and many were tested using either NorlandAC/NC3000 or CC6000. In particular, CC6000 interferometer is used by more and more factories because of its superior cost performance.

3. Optical fiber end face scratch detection, and use video optical fiber magnifier for observation. For example, many factories use fibviewfv-400pa for inspection. The instrument can give a clear picture of the human body and is extremely simple to operate. Some customers also use fibkey-5600 type variable magnifier for testing. This instrument integrates 400 times, 200 times and 80 times magnifiers into one, which can clearly and conveniently observe the fiber end face and plug end face. Of course, you can also use relevant software for automatic checking.

4. For fiber optic tension test, it is necessary to test the tension that fiber optic connector can withstand.

5. In the experiment of ambient temperature, it is necessary to test the performance indexes of fiber optic connector under different ambient temperatures.
