What Is The Difference Between Carrier-Grade And Network-Grade Fiber Optic Jumpers?


Why should the fiber optic jumper be divided into telecommunications and network grades? In order to make everyone aware of these two levels of products at a glance, let's take a look at the difference between them today!

Fiber optic jumpers are used to make jumpers from equipment to fiber optic cabling links. It has a thick protective layer and is generally used for the connection between the optical transceiver and the terminal box. It is used in some fields such as optical fiber communication systems, optical fiber access networks, optical fiber data transmission, and local area networks.

Network-grade fiber optic jumpers and carrier-grade fiber optic jumpers:

Fiber optic patch cords at the network level are slightly worse than those at the carrier level because of the greater attenuation. Network-level jumpers generally have very low requirements. Packets are lost during transmission, and the data is generally greater than 0.3dB.

The carrier-grade fiber optic jumper is better than the network-level because it has less attenuation and is not easy to lose data. Like China Netcom, China Mobile, China Unicom and Nokia, their servers are all carrier-grade fiber optic jumpers.

If the fiber optic jumper you choose is used for video optical transceivers, it is recommended to choose a telecommunication-grade jumper. Video transmission is the most important. General carrier-grade specifications: Insertion loss is less than 0.3dB and return loss is greater than 45dB.

It is said that carrier-grade fiber optic jumpers are better than network-level, so what are the differences between them?

1. Degree of attenuation

The carrier-grade fiber jumper has less attenuation than the network-grade fiber jumper, and the transmission data is more stable and not easily lost.

2.Grinding times

The polishing process of carrier-grade fiber jumpers is generally five times, and network-grade fiber jumpers are four times.


The price of carrier-grade fiber jumpers is higher than that of network-grade fiber jumpers.
