As an optical passive device, the optical fiber attenuator is used for debugging the optical power performance in the optical communication system, debugging the calibration and correction of the optical fiber instrument, and attenuating the optical fiber signal. The product is made of attenuated fiber doped with metal ions, which can adjust the optical power to the required level.
Both ends of the fiber optic adapter can be inserted into fiber optic connectors of different interface types to realize the conversion between different interfaces such as FC, SC, ST, LC, MTRJ, MPO, E2000, etc. It is widely used in optical fiber distribution frames (ODF), optical fiber communication equipment , instruments, etc., superior performance, stable and reliable. Some people on the market call fiber optic adapters also fiber optic connectors, but these are actually two different products.
Fiber Attenuator
Attenuators are like sunglasses that protect your eyes from harsh light by absorbing excess light energy. Fiber optic attenuators can act like sunglasses to protect the fiber by operating in a specific wavelength range.
The criteria for a good fiber attenuator is to replace the reflecting fiber by absorbing the additional fiber. Because in optical fiber communication, it is necessary to use lower optical power without damaging the optical fiber attenuator.
Adapters are available in standard and conversion types, also known as flanges. Adapters are required for jumpers, pigtails, and terminal boxes. The main function is the connection between devices. For example, fiber patch cords, which are called patch cords, are equipped with adapters at both ends of an optical fiber. An adapter is installed at one end of the ZR Cable optical fiber jumper, which is called pigtail.
Now there are set-top boxes for watching TV at home, and the small circular device behind the set-top box is a kind of adapter. The key to fiber connection is the precise alignment of the fiber core, so traditional connection methods (such as welding) have certain defects. The difference is that each fiber optic adapter has an alignment sleeve inside, which can ensure the accuracy of the connection and achieve high-performance connection between fiber optic patch cords.
