Details Introduction

Through 1480nm or 980nm pump technology, erbium doped fibre can realize 35nm amplification bandwidth, and maintain flat gain as well as ideal power conversion efficiency. Erbium doped fibres is specially designed for high performance, low noise requirements amplifier, for example, optical preamplifier, booster and in-line amplifier in the WDM communication system. Erbium doped fibre has been optimized through erbium and aluminum codoping technology to ensure the high performance.

Applications
