Abstract
By using a distributed feedback buried heterostructure InGaAsP/InP laser diode emitting at 1.53 μm, 21.7 km single-mode fibre transmission at 280 Mbit/s was successfully carried out without any noticeable degradation in a waveform and an error rate. This result indicates that a long-haul optical telecommunication system with a repeater span of over 70 km is possible in the fibre low-loss region of 1.5 μm to 1.6 μm wavelength.
