Abstract :
An optical sensitivity improvement of 1.5 dB was produced by moderate cooling of a commercially available 100 ¿m p+-n Ge APD in a transimpedance receiver, built on a standard printed circuit board. At 1.3 ¿m and 140 Mbaud, ¿45.2 dBm was achieved, making this receiver highly competitive where cooling is permitted.
