565 Mbit/s duplex transmission at 1300 nm over 50 km of single-mode optical fibre

Abstract

Results are reported from a laboratory trial in which high-capacity duplex transmission has been demonstrated across a 50 km section of single-mode fibre. The system simultaneously transmits a 647 Mbaud signal in each direction at 1300 nm using BH lasers, Ge APD-based optical receivers and fused biconical-taper directional couplers.
