The classification of fiber optical patch cord, detailed!

Posted on 21st Jul 2018 @ 6:10 PM

 

Fiber patch cords are used to make patch cords from the device to the fiber optic cabling link. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the terminal box.
Optical fiber jumpers (also known as fiber optic connectors) refer to the connector plugs on both ends of the cable for optical path active connection; the plug at one end is called pigtail. Optical Fiber Patch Cord/Cable is similar to coaxial cable except that there is no mesh shield. The center is the glass core of light transmission. In a multimode fiber, the core has a diameter of 50 μm to 65 μm, which is roughly equivalent to the thickness of a human hair. The single mode fiber core has a diameter of 8 μm to 10 μm. The outer periphery of the core is surrounded by a glass envelope having a lower index of refraction than the core to retain the fiber within the core. Next to it is a thin plastic jacket to protect the envelope.
Single multimode difference
Optical fiber jumpers can be divided into common single-mode and multi-mode jumpers of silicon-based optical fibers according to different transmission media, and other optical fiber jumpers such as plastics; the structure of the connector can be divided into: FC Jumpers, SC jumpers, ST jumpers, LC jumpers, MTRJ jumpers, MPO jumpers, MU jumpers, SMA jumpers, FDDI jumpers, E2000 jumpers, DIN4 jumpers, D4 jumpers, etc. form. More common fiber jumpers can also be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST and so on.
Single-mode fiber: The general fiber jumper is indicated by yellow, the connector and the protective cover are blue, and the transmission distance is long.

Single-mode fiber: The general fiber jumper is indicated by yellow, the connector and the protective cover are blue, and the transmission distance is long.

 

Multi-mode fiber: Generally, the fiber jumper is indicated by orange, and some are indicated by gray. The connector and protective cover are made of beige or black; the transmission distance is shorter and shorter.

Precautions

 

The optical transceivers at both ends of the optical fiber jumper must have the same wavelength. The two ends of the optical fiber must be optical modules of the same wavelength. The simple distinction is that the color of the optical module must be the same. In general, short-wavelength optical modules use multimode fiber (orange fiber), and long-wavelength optical modules use single-mode fiber (yellow fiber) to ensure data transmission accuracy.

 

Do not over-bend and wrap the fiber during use, which will increase the attenuation of light during transmission.

 

After the fiber jumper is used, the fiber connector must be protected with a protective cover. Dust and oil can damage the coupling of the fiber.

 

If the fiber connector is dirty, you can use a cotton swab to clean the alcohol, otherwise it will affect the communication quality.

 

1. The fiber jumper ceramic ferrule and the ferrule end face must be wiped clean with alcohol and absorbent cotton before use.

 

2. The minimum bending radius of the fiber is not less than 150mm when used.

 

3. Protect the ferrule and the ferrule end face to prevent bumps and pollution, and bring the dust cap in time after disassembly.

 

4. Do not look directly at the fiber end face when the laser signal is transmitted.

 

5. In case of damage caused by man-made and other force majeure factors, the damaged fiber jumper should be replaced in time.

 

6. Read the instructions carefully before installation and install and debug under the guidance of the manufacturer or dealer.

 

7. If an abnormal situation occurs in the optical network or the system, the fault elimination method can be used to test one by one. You can do the continuity test when testing or troubleshooting the jumper. You can usually use the visible laser pointer to judge the entire fiber link. Or further use the precision fiber insertion loss loss detector to test its various indicators. If the indicator is within the qualified range, the jumper indication is normal, otherwise it is unqualified.
