Fiber Optic Attenuator is used to reduce signal power in fiber optic links by a fixed or variable loss. It can be mainly divided into fixed bulkhead (female-female) fiber optic attenuator, fixed plug-in (female-male) fiber optic attenuator and variable fiber optic attenuator. ANC adopts mature attenuation fiber technology, and is able to provide high quality fiber optic attenuators at favorable price and fast delivery. In ANC, single mode and multimode 62.5/125 or 50/125 fiber optic attenuators are available. The attenuation range of such fiber attenuator can be from 1dB to 25dB at 1dB increment. The attenuator type has but not limit to SC/UPC, SC/APC, FC/UPC, FC/APC, LC/UPC, LC/APC, ST/PC, MU, E2000, fiber optic attenuators.
