Structure:

Fiber optic jumper (also known as optical fiber connectors) refers to the cable on both ends mount connector plug, used to implement the light path activity connection;At one end with a plug is called the tail fiber.Fiber optic jumper OpticalFiberPatchCord/Cable and coaxial Cable are similar, but no mesh shielding layer.The center is the spread of the light glass core.In multimode optical fiber core diameter is 50 microns to 65 microns, roughly the comparative with the thickness of a human hair.And the diameter of the single mode fiber core was 8 microns to 10 microns.Core surrounded by a layer of refractive index is lower than the core glass envelope, to make the optical fiber to keep within the core.Outside is a thin layer of plastic coat again, to protect the sleeve.

Features:

1. Low insertion loss

2. The repeatability

3. The return loss is big

4. Each performance is good

5. The temperature stability is good

6. Strong tensile performance

Application:

Fiber optic jumper wire products are widely applied to: telecommunication room, optical fiber to the home, local area network, optical fiber sensor, optical fiber communication system, optical fiber transmission equipment, such as national defense combat readiness.Applicable to optical fiber cable network, telecommunication network, computer network and optical test equipment.Segmentation is mainly used in several aspects.

1. The optical fiber communication systems

2. Optical fiber access network

3. Optical fiber data transmission

4. Optical fiber CATV

5. A local area network (LAN)

6. The device under test

7. Optical fiber sensor

Selects the guidelines:

Fiber optic jumper by termination type points mainly has the following three types: ST - ST, SC - SC, ST - SC.According to the optical fiber type points mainly include two categories, single-mode optical fiber and multimode fiber.Of the specifications of the jump line length is 0.5 m, 1 m, 2 m, 3 m, 5 m, 10 m, etc.According to the cable outer sheath material can be divided into ordinary, ordinary flame retardant, low smoke zero halogen type (LZSH), low smoke zero halogen flame retardant, etc.

According to the requirements of the level of building fire protection and for materials refractory, integrated wiring system should take corresponding measures.In an area where flammable and building shaft inside cloth cable or optical cable, flame retardant cable and cable should be adopted;In large-scale public places appropriate USES flame retardant, low smoke, low toxicity of cable or optical cable;Between adjacent equipment or transfer of flame retardant wiring equipment should be adopted.

How to detect:

Use inserts return loss instrument first used to ascertain if jump line light pass through light pen measured optical fiber isn't broken measure indicators generally telecom level indicators: insertion loss is less than 0.3 dB return loss is greater than 45 dB.

Performance test of fiber optic jumper wire is divided into:

1. Detection of optical performance, including return loss/insertion loss test.Test instrument can use FibKey7602 return loss/insertion loss integration tester.

2. The end face geometry test, test parameters including the radius of curvature, vertex offset, fiber optic height, etc.Test instrument is interferometer, a lot of people using NorlandAC/NC3000 or CC6000 test.Especially CC6000 interferometer because of superior cost-effective, more and more factories using this instrument.

3. The fiber end surface scratch test, using video optical magnifying glass to observe, such as many factories use FibViewFV - 400 pa for inspection.The instrument can give the clear image, operation is extremely simple.Also have customers use FibKey - 5600 type variable multiple magnifying glass for testing, the instrument set 400 times, 200 times, 80 times the magnifying glass in the integral whole, can be clear and easily observe fiber end face and insert core surface.Of course you can also use the relevant software for automatic inspection.

4. Optical fiber tensile test, need to test tensile strength of the optical fiber connector to withstａnd size.

5. The environment temperature experiment, the need to test the performance of the optical fiber connectors under the condition of different environmental temperature indicator.
