Comparative high power conversion efficiency of C- plus L-band EDFA

Comparative high power conversion efficiency of C- plus L-band EDFA

A dual-band erbium-doped fibre amplifier (EDFA) with high power conversion efficiency is proposed and demonstrated. The EDFA covers both the C-band around 1.55μm and the L-band around 1.58μm. The same signal gain can be achieved with 42% less pump power and 47% shorter erbium-doped fibre length comp...

Zusammenfassung:A dual-band erbium-doped fibre amplifier (EDFA) with high power conversion efficiency is proposed and demonstrated. The EDFA covers both the C-band around 1.55μm and the L-band around 1.58μm. The same signal gain can be achieved with 42% less pump power and 47% shorter erbium-doped fibre length compared to an alternative, conventional parallel type, dual-band EDFA.
