Abstract :
GeAPD optical receiver sensitivity at 1.3 ¿m was studied up to 2 Gbit/s. High sensitivity of the receiver and a low coupling loss of 4 dB between a laser and a single-mode fibre achieved by a mocrolens made it possible to transmit 2 Gbit/s signals over a 44.3 km single-mode fibre. The optical receiving level was ¿29.4 dBm at a 10¿9 error rate and no degradation occurred by fibre dispersion. The data rate by repeater spacing product of 88.6 (Gbit/s)·km was achieved at 1.3 ¿m.
