Continuous 16.4-THz Bandwidth Coherent DWDM Transmission in O-Band Using a Single Fibre Amplifier System
A record continuous transmission bandwidth of 16.4 THz is demonstrated in O-band fibre transmission over an 80-km single-mode ultra low-loss fibre span. Bismuth-doped fibre amplifiers with an output power of 25 dBm and a low noise figure of 3.6 dB compensate a loss of 80-km fibre span. An O-band wavelength selective switch with a 16.4 THz bandwidth maximises the transmission capability and enabled optimisation of the input spectrum shape to reduce nonlinear interference near zero dispersion, resulting in a potential achievable information rate of over 100 Tb/s to be reached.
