FTTH single/ multi mode fiber optic attenuator

Brief Introduction

Fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. This is often a requirement in Dense Wave Division Multiplexing (DWDM) and Erbium Doped Fiber Amplifier (EDFA) applications where the receiver cannot accept the signal generated from a high-power light source.

 

 

 Features

1. Metal ion doped fiber

2. High-power light source durability

3. Wavelength independence

4. Attenuation levels ranging from 1dB to 30dB, with standard and premium tolerances, plus custom configurations

5. 1310nm, 1550nm, 1250-1625nm and 1350/1550nm dual wave lengths

6. FC, SC, ST, LC ,optional

7. Plastic or metal housing material

 

Applications

1. Erbium Doped Fiber Amplifiers (EDFA)

2. Dense Wave Division Multiplexers (DWDM)

3. Optical Network Equipments,optical Test Equipments

4. Overpowered fiber optic systems
