Duplex-diplex optical transmission in the 1300 nm and 1500 nm fibre windows: an installed system

Abstract

Results are presented from the first installed route in which two separate optical transmission systems have been combined using duplex and wavelength-division multiplexing (WDM) on a single fibre. Fused biconical couplers and wavelength-division multiplexers were used on a 30 km installed single-mode optical fibre route. Details of the observed receiver crosstalk penalties are presented.
