Today, I'd like to share with you a knowledge point. The details are as follows:
The optical fiber interface is used to connect the physical interface of the optical fiber cable.
Usually, there are several types, such as SC, ST, and FC, which are developed by the Japan NTT company.
FC is the abbreviation of Ferrule Connector, its external strengthening way is a metal sleeve, the fastening way is a screw buckle. The ST interface is usually used for 10Base-F, and the SC interface is usually used for 100Base-FX. Optical fibers can be divided into two modes: single-mode (long-wavelength laser) and multi-mode (short-wavelength laser). The connection distance of a single-mode optical cable can reach 10 kilometers, and the connection distance of a multimode optical cable is much shorter. It is 300 meters or 500 meters (mainly depending on the laser. There are two kinds of light sources that generate short wavelength laser, one is 62.5, one is 50).
In addition, there are two kinds of connection parts of fiber optic cable. One kind of SC interface is a 1GB interface, and another is an LC interface for a 2GB interface. FC is the abbreviation of Ferrule Connector, indicating that its external reinforcement is made of a metal sleeve, the fastening way is screwdriver PC is the abbreviation of Physical Connection, indicating that its butt end face is physical contact, that is, the convex arch structure on the end surface.
SC (F04) type optical fiber connector: molded plug-in coupling single-mode optical fiber connector. The shell is made of molded technology, made of cast glass fiber plastic, and has a rectangular shape. The plug sleeve (also called a pin) is made of precision ceramics, and the coupling sleeve is a metal slotted bushing structure. The size of its structure is the same as that of the FC type. The PC and APC grinding methods are adopted for the end face treatment. This kind of connector has the advantages of low cost, easy operation, low fluctuation in insertion loss, high compressive strength, and high installation density.
Thanks.
