What is the difference between network-level and carrier-grade fiber optic patch cords? Fiber optic patch cords are used as patch cords from equipment to fiber optic wiring links. Fiber optic patch cords can be regarded as wires in the circuit. Reflection, the equivalent of tying light in an optical fiber, directs it where you want it to go.

Optical fiber jumpers are divided into network grade and carrier grade. First of all, let's talk about network grade optical fiber jumpers. The network grade is slightly worse than the carrier grade. The reason for the poorer is that the attenuation is larger. Network-level jumpers generally have very low requirements and will lose packets in transmission.

The network level is slightly worse than the carrier level, in short, the attenuation is larger. Network-level jumpers generally have very low requirements (packets will be lost during transmission, and data is generally larger than 0.2DB). Carrier-level jumpers are relatively much better than network-level jumpers because of their small attenuation. Not easy to lose data. Like China Netcom, China Mobile, China Unicom, and Nokia, all their servers use carrier-grade jumpers. If it is used on the video optical transceiver, it is recommended that you choose a telecom-grade jumper.

The practice of network-grade jumpers and carrier-grade jumpers is like leaking a secret here. In fact, the network-level jumper and the carrier-level jumper are the same in practice, except that the carrier-level jumper has a different process when grinding, and the network jumper has four processes. Carrier-grade grinding has 5 processes. Oh, this is the inside story of making fiber jumpers. In fact, at the time of production, the cost is similar, but the carrier-grade jumper is much higher than the network-grade jumper.

If the fiber jumper you choose is used on the video optical transceiver, it is recommended to choose a carrier-grade jumper. The general carrier-grade indicator is that the insertion loss is less than 0.3dB and the return loss is large.
