Optical Attenuator
The attenuation value of a fixed optical attenuator is actually its insertion loss. For a variable optical attenuator, the attenuation value includes its attenuation and insertion loss, and the smaller the

Fiber-optic Attenuators – fixed or variable attenuation, working
Other devices are variable optical attenuators, providing an amount of insertion loss which is adjustable within some range (e.g. 2 dB to 50 dB), e.g. with some adjustment wheel or screw, or through an

How a Variable Optical Attenuator Works – Principle, Types
Optical attenuation is the reduction of optical power as light propagates. Attenuation can be caused intentionally — by inserting an attenuator — or unintentionally — through fiber loss,

VARIABLE OPTICAL ATTENUATOR (ULTRA LOW LOSS VOA)
Variable Optical attenuators are commonly used to test optical parameters by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match a fixed power signal.

Variable Optical Attenuator (Manual and MEMS)
Single mode fiber only for MEMS. 1.0dB maximum applies to 1310 and 1550nm only. Higher insertion loss up to 1.5dB applies 400~1200nm. 80dB possible by special design.
