Abstract :
A nonrepeated fibre transmission experiment over 308 km of conventional optical fibre is reported at 2.5 Gbit/s in a CPFSK heterodyne detection system. The system has a sensitivity of -46.7 dBm or 67 photons/bit at 10-9 BER and has the maximum allowable attenuation of 55.1 dB without an optical amplifier.
