Fiber Jumper Of The Fiber Closure


The complete optical communication is inseparable from the fiber jumper, so we need to understand some of the relevant knowledge of fiber jumpers, its application is particularly wide, such as the communications room, fiber to the home, local area network, fiber optic sensors, optical fiber communication systems And so on, it also played an important role in Fiber Closure.

We have many misunderstandings in network cabling. Many people often think that fiber patch cords play a minor role in the network. In fact, fiber jumper is one of the factors that can affect the network performance. A fiber patch cord with poor transmission performance can cause a drastic drop in system performance. Perhaps in the initial installation process, the use of low-quality jumpers can reduce the cost of the entire network cabling system. However, doing so can jeopardize the quality and reliability of the network.

The wavelengths to be transmitted and received at both ends of the jumper should be the same, that is, the optical fiber must have the same wavelength at both ends of the optical module. The simple method of distinguishing is that the light modules should have the same color. In general, short-wavelength optical modules use multimode optical fibers (orange fibers), and long-wavelength optical modules use single-mode fibers (yellow fibers) to ensure data transmission accuracy.

Do not excessively bend and circulate the fiber during use. This will increase the attenuation of light during transmission. The minimum bend radius of the optical fiber when used is not less than 150mm. After the fiber jumper is used, the fiber connector must be protected by a protective sleeve. Dust and oil entering the connector will damage the coupling of the fiber. If the fiber connector is dirty, you can use a cotton swab to clean it with alcohol, otherwise it will affect the communication quality. Abnormal conditions in fiber optic networks or systems can be tested one by one by troubleshooting. When testing or troubleshooting a jumper fault, you can perform a continuity test first, and you can usually use the visible laser pointer to determine the lighting of the entire fiber link. Or further use the precision optical fiber insertion loss return loss tester to test its various indicators. If the indicator is within the qualified range, the jumper indication is normal, otherwise it is unqualified.
