Fiber optic patch cords are used as patch cords from equipment to fiber optic cabling links. They have a thicker protective layer and are generally used for the connection between optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.
Fiber optic patch cords are divided into network-grade and telecom-grade.
Network-grade fiber optic patch cords are slightly worse than telecom-grade patch cords because of their greater attenuation. Network-grade patch cords generally have very low requirements, and packet loss will occur during transmission. Data is generally greater than 0.3dB.
Telecom-grade fiber optic patch cords are better than network-grade ones because they have less attenuation and are not prone to data loss. Companies like China Netcom, China Mobile, China Unicom, and Nokia all use telecom-grade fiber optic patch cords for their servers.
If the fiber optic patch cord you choose is used on a video optical terminal, it is recommended to choose a telecom-grade patch cord, as video transmission is the most important. General telecom-grade indicators: insertion loss is less than 0.3dB and return loss is greater than 45dB.
It is said that telecom-grade fiber optic patch cords are better than network-grade ones, so what are the differences between them?
1. Attenuation degree
Telecom-grade fiber optic patch cords have less attenuation than network-grade fiber optic patch cords, and the transmission data is more stable and not easily lost.
2. Grinding times
The grinding process of telecom-grade fiber optic patch cords is generally 5 times, and that of network-grade fiber optic patch cords is 4 times.
3. Price
The price of telecom-grade fiber optic patch cords is higher than that of network-grade fiber optic patch cords.
