A fiber optic attenuator is a passive device used to reduce the amplitudeof a light signal without significantly changing the wave form itself.This is a requirement in dense wave division multiplexing and erbiumdoped firer amplifier applications where the receiver cannot accept thesignal generated from a high power light source.
Fiber Opitc Attenuator has perfect optical property and high reliability with low loss,good directivity,good optical wave flatness,good stability.
