Fiber Optic Attenuator Single Mode LC Input / Output Form Blue color
Description
Optical fiber attenuator is a passive device used to reduce the intensity of optical signal without changing the transmission wavelength.
This device is used in transmission links such as dense wavelength division multiplexer (DWDM) and erbium-doped fiber amplifier (EDFA) with high intensity optical power. Attenuation is required because the receiver cannot receive high optical power.
Fixed fiber optic attenuators are available in LC, SC, ST,and FC style with APC and UPC polish. Generally, single-mode systems, especially short links, often have too much power and need attenuators. Therefore, fixed fiber optic attenuators are usually single-mode types. The most commonly used type is LC single mode female to male and female to female fixed fiber optic attenuator.
