What are the classifications of fiber optic adapters?

Optical fiber adapters, also known as optical fiber couplers and optical fiber flanges, are mainly used to connect the same or different optical fiber active connectors in optical fiber exposure, so that the optical path can be smoothed with little loss.

It can precisely butt the two cross-sections of the optical fiber, so that the optical energy output by the emitting fiber can be coupled to the receiving optical fiber to the maximum extent, and minimize the impact on the system due to its intervention in the optical link. Applicable to telecommunication system, cable TV network, local area network, optical area network, FTTH optical fiber to the home, video transmission, test equipment.

The function of the fiber optic adapter is to realize the active connection between the fiber and the fiber. Small things, if the quality is not very good, there is nothing to underestimate the impact of the entire network system. Basically the requirements of a good fiber optic flange: small insertion loss, return loss, repeated mating, environmental stability and good mechanical properties.

Generally speaking, the most important thing is that there is no large insertion loss, and the insertion loss of the adapter is the attenuation of optical power caused by the access adapter system. Mainly because the optical fibers between the two are not concentrically connected. If the two fibers are arranged in a straight line, the deviation is zero and the insertion loss is minimal. In practical engineering applications, this is an impossible task, because of different cores, and different cores and cladding fibers, the concentricity of the fiber cladding and the inner hole of the pin hole and the outer diameter of the pin is wrong. Factors exist that can cause lateral deviations between fibers.

Common Types of Fiber Optic Adapters

There are many types of fiber optic adapters, mainly including LC fiber optic adapters, FC fiber optic adapters, SC fiber optic adapters and bare fiber optic adapters.

LC fiber optic adapter: This fiber optic adapter can be used for the connection of LC fiber optic jumpers or LC connectors, and it has various types such as LC-LC, LC-FC, LC-SC, LC-ST and LC-MU.

FC fiber optic adapter: This kind of fiber optic adapter can be used to connect FC fiber optic patch cords or FC connectors, there are different types such as square, single-mode and multi-mode, but these different types of FC fiber optic adapters all have metal shells and ceramic sleeves.

SC fiber optic adapter: It can be used to connect SC fiber optic patch cords or SC connectors, and there are many types, such as standard female-female SC adapters and hybrid SC adapters. Most SC fiber optic adapters come with ceramic ferrules, while the fiber type of SC fiber optic adapters with bronze ferrules is usually multimode.
