Extension in the reach of 1.3 mu m optical communication systems has traditionally been restricted by the availability of suitable low-noise fiber amplifiers. Addressing this challenge, we present the first repeatered wavelength division multiplexing (WDM) experiments using a bismuth-doped exhibits 8.4 THz (50 nm) of gain bandwidth in the O-band. WDM signals arranged either with coarse or dense wavelength spacings are transmitted over lengths of single-mode fibre (SMF)-28e ranging between 100 and 140 km.
