1~25dB Optional LC / APC Singlemode Fixed Fiber Optic Attenuator, Male-Female
Although fiber optic attenuators are normally used in singlemode circuits, because this is where the stronger lasers are used for distance transmission, we also have multimode attenuators available (upon special order) in 50/125 and 62.5/125 fiber sizes. Since these will be custom made, minimum order quantity (50+) and extended lead time (2-4 weeks) may be required.

The most common version of attenuators are, as shown below, male to female units, often called plug-style or buildout style. These plug-style attenuators simply mount on one end of a fiber optic cable, allowing that cable to be plugged into the receiving equipment or panel. We also have female to female (bulkhead) attenuators, often used to mount in patch panels or for connecting two fiber optic cables together. More expensive, but useful for testing, are variable attenuators which are adjustable between 1dB and 30dB. We also can custom build in-line attenuators where the attenuator is incorporated within a fiber optic patch cable, built to your specifications. The dB ratings are a measure of signal strength and can sometimes be confusing. The chart below will give you an idea of the percent of attenuation of your signal for specific dB values.
(1) Design flexibility with various connector style choices and attenuation levels.
(2) Designed to provide flat spectral attenuation required to function in all the wavelengths.
