DOI: 10.1007/s11801-019-9025-1
Abstract: In this letter, we propose a bidirectional optical amplification scheme for fiber-optic time transfer based on bidirectional wavelength-division multiplexing (WDM) transmission. The proposed scheme employs single unidirectional erbiumdoped fiber amplifier (Uni-EDFA) for commercial optical networks… read more here.
