For lan jumpers, pigtails, fiber optic connectors may have a lot of readers are not very clear, the following to tell you about their differences

1.A pigtail

Usually pigtail for connecting fiber optic cable, pigtail only one connector, the fiber jumper cut, divided into two is the pigtail.

2. Fiber optic connectors

Fiber optic connector, also known as coupler, generally used in the fiber box, pigtail fiber in the fiber box to connect one end of the coupler, stuck in the fiber box, another section to connect the fiber jumper, coupler can not, just to prevent pigtail easy damage.

3. Lan jumpers

Lan jumpers are single or dual.

(1) single-core: a fiber optic cable, two connectors, monitoring are single-core, in a line responsible for the information received with the hair, this is called simplex transmission.

(2) dual-core: two fiber optic cable, four connectors, the network are used in dual-core, in the two lines responsible for the signal of a received, this is called the meaning of duplex transmission.

4. connector

(1) round connector

Threaded bayonet is: ST head, mainly for the old program in the use of fiber box, the flexibility of the threaded bayonet without screw mouth!

Threaded mouth: FC head, mainly used for monitoring system, generally all optical terminals are FC port

(2) square connector

Generous head: SC head is mainly used for all domestic fiber optic transceivers, are SC head!

Small square head: LC head high precision, mainly for the switch of the optical module, Huawei and Cisco's three or two switches or other special industrial equipment!

The above is a brief introduction to the differences between lan jumpers, fiber optic connectors, and pigtails. For more information on fiber optic connectors, please visit kingsignal's official website.
