Optical attenuator



fiber optic attenuator


Optical attenuators are used in the fiber optic links to reduce the optical power at a certain level.

Types of fiber optic attenuators:
1. Female to male plug style optical attenuator (MU, SC, FC, ST, LC) PC& APC polish available
2. Flange stype fiber optical attenuator
3. Adjustable fiber optical attenuator (FC style) Attenuation scale:0~30dB
4. IN-Line style fiber optical attenuator

Features of fiber optic attenuators:
– Low insertion loss
– Attenuation from 1dB to 30dB
– Single mode and Multi mode versions
– PC, UPC, and APC polish types optional
