A germanium avalanche photodiode of 30 μm active area diameter has been fabricated and tested. The multiplied dark current is as low as 5 nA at room temperature. A module using this diode and a spherical lens has been assembled and coupled with a single-mode fibre of core diameter 10 μm. The quantum efficiency of the module is 90% at 1.3 μm. The sensitivity is measured at 45 Mbit/s and at 1.3 μm. Minimum detectable powers obtained for 10−11 error rate are −51.9 dBm and −50.7 dBm at 25°C and 50°C, respectively.
