SC LC ST FC SM/MM Simplex Duplex Fiber Optic Patch Cord 3.0MM 2.0MM

Attention to the use of fiber optic jumpers

The transmit and receive wavelengths of the optical modules at both ends of the fiber jumper must be the same, that is to say, the two ends of the fiber must be optical modules with the same wavelength. The simple way to distinguish is that the colors of the optical modules must be consistent. Generally, the short-wave optical module uses multimode fiber (orange fiber), and the long-wave optical module uses single-mode fiber (yellow fiber) to ensure the accuracy of data transmission.

Do not excessively bend or loop the optical fiber during use, as this will increase the attenuation of light during transmission.

After using the optical fiber jumper, the optical fiber connector must be protected with a protective sleeve. Dust and oil will damage the coupling of the optical fiber.

If the optical fiber connector is dirty, use a cotton swab dipped in alcohol to clean it, otherwise the communication quality will be affected.

1. Before use, the ceramic ferrule and ferrule end face of the optical fiber jumper must be wiped clean with alcohol and absorbent cotton.

2. When in use, the minimum bending radius of the optical fiber is not less than 150mm.

3. Protect the ferrule and the end face of the ferrule to prevent bumps and pollution, and put on the dust cap in time after disassembly. Optical fiber jumper FC LC ST SC single-mode single-core yellow and white optical fiber pigtail

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

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

6. Read the instructions carefully before installation, and carry out installation and debugging under the guidance of the manufacturer's or dealer's engineer.

7. If there is an abnormal situation in the optical fiber network or system, you can use the troubleshooting method to test one by one. When testing or troubleshooting jumper faults, you can do a continuity test first. Usually, you can use a visible laser pointer to illuminate the entire optical fiber link. Or further use the optical fiber insertion loss and return loss tester to test its various indicators. If the indicators are within the qualified range, the jumper indicator is normal, otherwise it is unqualified
