Introduction And Interface Classification Of Fiber Optic Attenuators

   Optical fiber attenuator is a kind of optical device which can reduce the energy of optical signal. For the attenuation of input optical power, the distortion caused by optical receiver is avoided because of the high input power.Fiber Optic Attenuators

   As a kind of optical passive device, optical fiber attenuator is used for adjusting optical power performance in optical communication system, calibrating calibration of optical fiber instrument and attenuation of fiber signal. The product is made of a decaying fiber with metal ions and can adjust the optical power to the desired level.Fiber Optic Attenuators

   The optical fiber Attenuator test system has the characteristics of high attenuation precision, low additional loss and good stability. Mainly used in: Optical fiber communication system, optical fiber CATV, high-power optical device measurement, for the attenuation of input optical power, to avoid the optical receiver due to the high power of input optical distortion.Fiber Optic Attenuators

   The types of ports can be categorized into the following categories:

SC Optical attenuator: Applied to the SC fiber interface, it looks very similar to the RJ-45 interface, but the SC interface appears to be more flat, the difference is still the inside of the tablet, if it is 8 fine copper touch piece, it is RJ-45 interface, if is a copper column is SC fiber interface.Fiber Optic Attenuators

    LC Fiber Attenuator: Applied to LC Fiber interface, connecting SFP module connector, it is made of modular Jack (RJ) latch mechanism with convenient operation. (commonly used by routers)

    FC Fiber Attenuator: Used in FC fiber interface, external strengthening method is the use of metal sets, fastening mode for turnbuckle. Generally used on ODF side (most of the wiring rack)

    St Fiber Attenuator: Used in St Fiber interface, often used in fiber optic wiring frame, the shell is circular, fastening mode for turnbuckle. (for 10 Base connections, connectors are usually St types.) Used in fiber optic wiring rack)
