How to Classify Fiber Optic Patch Cords?

Nowadays, fiber optic patch cords are widely used in the telecommunication room, local area network, optical fiber communication system or other devices. They are the cables that connect the devices and the fiber optic cabling link, generally applied into connecting the optical transceivers and the terminal boxes. They have a thick layer for protection. Fiber optical patch cords are the similar to the coaxial cable, but they don’t have a mesh shield. The glass core of light propagation is in the center.

Fristly, according to their transmission medium, fiber optic patch cords suppliers often provide two types of them. They are singlemode fiber and mutimode fiber. The core diameter of mutimode fiber is 50μm ~ 65μm, as thin as the human’s hair. Mutimode fiber is often in yellow, and its connector and protective case are usually in blue. Singlemode fiber’s core diameter is 8μm~10μm. It is often in orange or sometimes in gray, and they usually use the beige or black connector and protective case. In the part of transmission distance, mutimode fiber is applied in the short transmission distance, while the singlemode fiber is applied in the long transmission distance.

Secondly, according to their connector form structure, fiber optic patch cords suppliers can offer various kinds, such as FC jumper, SC Jumper, ST Jumper, LC jumper, MTRJ jumper, MPO jumper and so on. Now the commonly used fiber optic patch cords are FC, SC, ST and LC jumpers.

• FC jumper generally is adopted on ODF side, using a metal sleeve to reinforce its external surface, and the turnbuckle to fasten itself.
• SC jumper, it has rectangular shell, using the latch type to fasten, and do not need rotation. It is mostly used on the router switch.
• ST jumper is commonly used in fiber optic patch panels with the turnbuckle fastened. It has rounded shell. Commonly, it is used in optical fiber distribution frame.
• LC jumper is made by the RJ latch mechanism which is operated easily, commonly used on the routers.

What is more, according to the material of their outer sheath, fiber optic patch cords suppliers can offer four types. They are ordinary jumper, common flame jumper, low smoke zero halogen jumper and halogen flame jumper. The point common flame jumper different from the ordinary jumper is that the insulator of common flame jumper won’t burn when it is in the high temperature. Relatively, it is safer than ordinary jumper. Low smoke zero halogen jumper is the environmentally friendly jumper that means it has non-halogen such as F, Cl, Br and I, and also does not contain Pb, Cd, Cr and Hg. In the case of combustion, it can’t release halogen-containing gases, and the smoke density is very low. And halogen flame jumper has all the advantages of low smoke zero halogen jumper. In addition, it has another advantage that in the high temperature its insulator won’t burn. This advantage is as same as common flame jumper. After a comprehensive comparison, the halogen flame jumper could be the bestseller.

Recently, there are more and more fiber optic patch cords suppliers so that it is more convenient for customers to buy the fiber optic patch cords. If you don’t know what kind of patch cords you should buy, just follow the above classifications.
