IT Internet technology in the ever-changing development today, Gigabit Gigabit network is widely used, the cabling system put forward more bandwidth and higher speed. In the face of rising demand, lan-type cabling products due to high bandwidth, light weight, long transmission distance, etc., not only has been widely used in the trunk cabling system, but also into the desktop application.

This also brought back the curiosity of the lan, this article to take you to a preliminary understanding of the next lan jumper, pigtail and the difference between the two.

1.Lan jumpers

Lan jumpers are used to jump from the equipment to the lan optic cabling link, also known as lan optic connectors, with a thick protective layer, generally used in the optical terminal and the connection between the terminal box to achieve optical path active connection.

Lan jumpers according to the different transmission medium can be divided into common silicon-based lan single-mode, multi-mode jumper, as well as other plastic as the transmission medium lan jumpers; according to the form of connector structure can be divided into: FC Jumper, SC jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, d4 jumper and so on. The more common lan jumpers are FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST and so on.

In the course of the use of optical lan in the use of excessive bending and winding, this will increase the attenuation of light in the transmission process. lan optic jumper at both ends of the optical transceiver transceiver wavelength must be consistent, that is, both ends of the optical lan must be the same wavelength of the optical module, a simple distinction is the color of the optical module to be consistent. In general, shortwave optical modules use multimode lan (orange lan), long-wave optical module using single-mode lan (yellow lan) to ensure the accuracy of data transmission.

2. pigtail

Pigtail is only one end with a connector, and the other end is a lan optic cable core of the broken head, also known as pig tail line. Through the welding and other lan optic cable core connected, often appear in the lan terminal box, used to connect lan optic cable and lan optic transceivers.

The above is the lan jumper and pigtail distinction between the introduction, more on the lan jumper content, please pay attention to kingsignal official website.
