Finished or customized optical fiber cables usually come with a plug. There are many types of optical fiber heads, including SC, LC, etc. Let me popularize them for everyone!
FC type optical fiber connector: the external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. It is generally used on the ODF side (the most used on the distribution frame).
SC type fiber optic connector: Connector for connecting GBIC optical module, its shell is rectangular, and the fastening method is plug-and-pull latch type, without rotation. (Most used on router switches)
ST-type fiber optic connector: often used in fiber optic distribution frames, the outer shell is round, and the fastening method is a turnbuckle. (For 10Base-F connection, the connector is usually ST type. Commonly used in fiber distribution frame)
LC-type fiber optic connector: A connector that connects to an SFP module, which is made with a modular jack (RJ) latch mechanism that is easy to operate. (commonly used by routers)
MT-RJ: Square optical fiber connector with integrated transceiver, one end with dual fiber transceiver.
Generally speaking, the fiber optic cable connectors in our home use SC-SC. Since it is an optical fiber extension cable, we need a fiber optic cable with SC connectors at both ends. After roughly estimating the distance from your home, you can consider placing an order according to the length!
Note 2: Pay attention to the type of fiber optic cable
Before placing the order, I took a closer look at the types of fiber optic cables on Taobao. I didn’t know if I didn’t read them. In addition to the many types of interfaces, there are also many types of optical fiber cables, such as one-core two-steel wires, one-core three-steel wires, two-core three-steel wires, two-core four-steel wires, etc... which one should I buy?
The most important thing in the fiber optic cable is the core. One core and two steel wires means that there is one fiber core and two steel wires in the fiber optic cable, and so on! So if you judge what your fiber optic cable is used for? Very Simple, look at the connectors, how many connectors are the number of cores, one core is one connector, and four cores are four connectors!
Generally speaking, in order to save costs, the optical fibers for telecom home use are of the type of one core and two steel wires. You can see that your optical fiber connectors only have one SC connector!
Note 3: Don’t forget to buy the flange when you buy the line
The device you need at this time is called a flange! The flange is the same as the adapter for the network cable. It can connect two optical fiber cables together. According to the interface of the optical fiber cable, there are many interfaces of the flange, similar to the optical fiber cable connector. , we only need to buy the flange of the SC connector, connect the fiber optic cable at both ends, and connect the optical cat at the other end!
The connection method is also very simple, whether it is a light cat or a flange, there is a gap, just insert the protruding part of the SC connector!
Note 4: Open lines should still pay attention to the appearance
Basically, after finishing the fiber optic cable and the flange, the task of preparing to extend your own broadband fiber optic cable is done!
