Two Important Kinds of Fiber Attenuators
There are two important kinds of fiber attenuators: plug style (including bulkhead) and in-line. A plug style attenuator is utilized like a male-female connector where attenuation occurs inside the device, that’s, on the light path from one ferrule to another. Included in this are FC fiber optic attenuator, LC attenuator, SC attenuator, ST attenuator and much more. An in-line attenuator is connected to a transmission fiber by splicing its two pigtails.
The key of operation of attenuators are markedly different simply because they use various phenomena to lower the power of the propagating light. The easiest means would be to bend a fiber. Coil an area cable several times around a pencil while measuring the attenuation with a power meter, then tape this coil. Then you definitely got a primitive but working attenuator.
Most attenuators have fixed values which are specified by decibels (dB). They’re called fiber optic fixed attenuator. For instance, a -3dB attenuator should reduce intensity of the output by 3dB. Manufacturers use various light-absorbing materials to attain well-controlled and stable attenuation. For instance, a fiber doped with a transition metal that absorbs light in a predictable way and disperses absorbed energy as a heat.
Variable optical attenuator is also available, but it is usually a precision instrument utilized in making measurements. From Sopto, you can get the best Variable Attenuators Instrument.
