1, different interfaces
The FC interface is a circular threaded interface, and the external reinforcement method is a metal sleeve.
SC interface is blue and wide, and the shell is rectangular.
The LC interface has a small blue opening.
2. Different connection methods
The FC connector has a circular shape and is connected with the FC coupler by rotation.
The shell of SC connector is rectangular, and it is connected with SC coupler in a direct plug-in way without rotation.
LC connector is used to connect SFP optical fiber module, and adopts convenient modular jack (RJ) locking mechanism.
3. Different uses
FC is generally used on ODF side, and is most commonly used on distribution frames.
SC is most commonly used in router switches.
LC is usually used in routers.
Extended data:
Optical fiber jumper, also known as optical fiber connector, refers to installing connector plugs at both ends of optical cable to realize the movable connection of optical path; A plug at one end is called a pigtail. Optical fiber jumpers are similar to coaxial cables, except that there is no mesh shielding layer.
The center is the glass core of light propagation. In multimode fiber, the diameter of the core is 50μm~65μm, which is roughly equivalent to the thickness of human hair. The diameter of single-mode fiber core is 8 μ m ~ 10 μ m, and the fiber core is wrapped by glass cladding with lower refractive index than the fiber core, so that the fiber is kept in the fiber core. Outside is a thin plastic coat to protect the envelope.
