3dB ST Fixed Fiber Optic Attenuator Male to Female for equipment
General Description
As a optical passive devices, attenuators mainly used in fiber optic to debug optical power performance & optical instrument calibration correction & fiber signal attenuation to ensure the optical power in a stable and desired leve in the link without any changes on its original transmission wave.
Fixd Optical attenuators are used in the fiber optic links to reduce the optical power at a certain level.Commonly used fiber optic attenuators are the female to male type, which is also called a plug fiber attenuator. They are with ceramic ferrules and there are various types to fit different kinds of fiber optic connectors.
Fixed value fiber optic attenuators can reduce the optical light power at a fixed level,Variable fiber optic attenuators are with adjustable attenuation range. There are also attenuation fiber optic patch cables available, their function is same as attenuators and are used inline.
