Er-Doped Fibers

Classification:

Detailed introduction

Erbium-doped fiber has the characteristics of high gain, large gain bandwidth, ow noise around 1.5 μm wavelength which also matched with the low attenuation window of communication fiber, so that it is widely used in DWDM optical transmission network and CATV network to amplify optical signals. It have the characteristics of high conversion efficiency, accurate gain spectrum, and high batch consistency, which can satisfy the strict applications requirements in optical amplifiers.

Applications

CATV amplifier
DDM amplifier
LiDAR
