Something You Should Know Before Using Fiber Optic Jumper

Classifications of fiber optic jumper

Fiber optic jumper is a fiber optic cable with optical fiber connector plugs on both ends. Fiber optic jumpers are divided into the following three types by termination type basically: ST-ST, SC-SC, ST-SC.

According to the optical fiber type, optical fiber jumper mainly includes single-mode fiber and multimode fiber. The specifications of the jumper wire length are 0.5m, 1m, 2m, 3m, 5m, 10m and so on.

According to the fiber optic jumper connection structure, it can be divided into: FC fiber patch cable(Product Recommendation: 1m FC-FC Duplex 10G OM4 50/125 Multimode Fiber Patch Cable), LC fiber patch cable, MTRJ, MPO, MU, SMA, FDDI, E2000, DIN4, D4, etc.

According to the cable outer sheath material, fiber optic jumper can be divided into ordinary, ordinary flame retardancy, low smoke halogen, low smoke 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 the cloth cable or fiber optic cable, flame retardant cable and optical cable should be adopted. In large-scale public places should be flame retardant, low smoke, low toxicity; Equipment between should use flame retardant wiring devices.

Applications for fiber optic jumper

Fiber optic jumper wire is used for patch cords from the device to the optical fiber link. It has a thicker layer in using in optical transceiver and the connection between the terminal box.

1. Optical fiber communication system

2. Fiber-optic broadband access network

3. Optical fiber for CATV

4. Local Area Network(LAN)

5. Fiber optic instrument

6. OFS(optical fiber sensor)

7. Optical fiber data transmission system

8. Testing equipment

What should we pay attention to when using fiber optic jumper?

When using fiber optic jumper, you should make sure that wire light wavelength of transceiver module at the ends of the fiber optic jumper must be identical, that is to say, the ends of the optical fiber must be the same wavelengths as light module. A simple way to distinguish is the color of the optic module.

In general cases, short wave optical module uses multimode optical fiber with orange, and long wave module uses single-mode optical fiber with yellow. To ensure the accuracy of the data transmission, please do not bend the optical fiber jumper too excessively, which will increase the light attenuation in the transmission process. After using the fiber optic jumper, you must guard the fiber optic connector by protective material, dust and oil pollution which can damage the coupling of optical fiber.

Furthermore, to ensure the quality of the joint, you must pay attention to the radius of curvature.
Each fiber optic jumper should be in accordance with ISO/IEC and ANSI/TIA/EIA for durability, moisture, coupling stress, optical fiber tensile force and the moisture, temperature extremes, insertion force and cable tension stress, impact and vibration and other bad environment to meet the requirements.

4 Steps To Find Out The Fault In Fiber Optical Network

1.If the indicating lamp of fiber optical transceiver or optical module and twisted pair cable port is light?

a. If the transceiver optical port (FX) indicator is not light, make sure whether the fiber link is a cross-linked fiber link. A fiber optic patch cord is connected in parallel; the other end is connected to a cross pattern.

b. If A transceiver optical port (FX) indicator lights but B transceiver optical port (FX) indicator is not light, then the fault is the A transceiver side. One possibility is: A transceiver (TX) optical transmitter port is bad and B transceiver optical port (RX) fails to receive optical signal. Another possibility is: There is a problem in fiber link of A transceiver (TX) optical transmitter port. (fiber optical cable or fiber optic patch cord may break.)

c. Twisted pair (TP) patch cable indicator is not light, make sure whether the twisted pair wiring is wrong or the twisted pair connection is incorrect? Please use on-off tester to test. (mind twisted pair cable indicator of some transceivers will light until the fiber link is connected.)

d. some transceivers have two RJ45 ports: (To HUB) indicates that the cable connect to switch is a straight line; (To Node) indicates the cable connect to switch is a cross-line;

e. One side of some transceivers with MPR switch: Indicates the cable connect to switch is a straight line; DTE switch indicates the cable connect to switch is a cross-line;

2.If the fiber optic cable, fiber jumper has been broken?

a. Cable on-off detection: using laser flashlight, sunlight, light to against one side of cable connector or coupler; see at the other end if there is visible light? If there is visible light, it indicates that the fiber optic cable is not broken.

b. Fiber optic connection on-off detection: using laser flashlight or sunlight in front of one side of a fiber jumper, see at the other end if there is visible light? If there is visible light, it indicates that the fiber jumper is not broken.

3.Whether the half / full duplex mode is wrong?

One side of some transceivers with FDX switch: indicates full duplex; HDX switch: means half-duplex.

4.Using a optical power meter to test

The luminous power of optical transceiver or optical module under normal circumstances: multimode: -10db-18db; single mode 20 km: -8db-15db; single mode 60 km: -5db-12db. If the luminous power of fiber optic transceiver is: -30db-5db, then you can determine the transceiver has a problem.

How To Test Ethernet Cable With Network Cable Tester


Whether installing new cable or troubleshooting existing cable, cable testing plays an important role in the process. But do you know the process of using cable tester to test Ethernet cable? First we should know the product of Ethernet cable and network cable tester clearly.

About Ethernet Cable
An Ethernet cable is one of the most popular forms of network cable used on wired networks. An Ethernet cable has eight wires that are arranged in four pairs. For current to flow correctly, the wire pairs must be connected in the proper order. Ethernet cables normally support one or more industry standards including Category 5 (CAT5) and Category 6 (CAT6).

Ethernet cables are physically manufactured in two basic forms called solid and stranded. Solid Ethernet cables tend to offer better performance and protection against electrical interference, while stranded cables are less prone to physical cracks and breaks making them more suitable for travelers and portable devices.

Computer networks use Ethernet cables to allow computers in the network to “talk” to each other. Ethernet cables connect network devices on local area networks such as PCs, modems, routers, switches and Fiber Optic Adapters. They transmit data using the Ethernet protocol.

About network Cable Tester

Basic network cable testers can test for simple connectivity issues but may not identify other problems that cause the cable to malfunction. Cabling may not work when it is near a source of interference or if the cable is too long. Intermittent faults may develop that do not show up when the cable is tested. Sometimes the problem is not sustained long enough to show up on the tester. Professional-level network cable testers may not only tell if an open circuit exists, but may identify where the break is located. Some also identify the gauge of wire used and can generate their own signal to test for interference.

When connected to an Ethernet cable, a network cable tester tells if the cable is capable of carrying an Ethernet signal. If the cable carries the signal, this indicates that all the circuits are closed, meaning that electric current can move unimpeded through the wires, and that there are no short circuits, or unwanted connections, in the wire. Network cable testers vary in complexity and price, but a basic tester consists of a source of electrical current, a measuring device that shows if the cable is good, and a connection between the two, usually the cable itself.

How to test Ethernet cable with Ethernet cable tester?

1.Reboot your modem/router. Unplug the power cord or hold down the reset button on your modem or router. Wait for 30 to 60 seconds then turn your modem/router back on.

2.Wait for your modem/router to re-establish a connection. Depending on your network hardware, it might take two to three minutes. If the problem persists, then try the network cable tester.

3.Turn on the network cable tester and plug one end of the cable into the “IN” Ethernet input on the network cable tester and the other end into the “OUT” input on the network cable tester.

4.Press the “Test” button on the network cable tester. The tester will send a signal across the Ethernet cable. If the signal gets from one end of the cable to the other, the tester will let you know if the test was successful, by displaying a green light, or unsuccessful, by displaying a red light.

5.Replace the Ethernet cable. If the test was unsuccessful, replace the bad Ethernet cable with a good one.

Follow the steps above, you generally know the error during installing new cables or troubleshooting existing cable. Correct it and finally have a smooth network.
