1.2 Gbit/s, 201 km optical DPSK heterodyne transmission experiment using a compact, stable external fibre cavity DFB laser module

摘要

An optical DPSK heterodyne transmission experiment was performed at a bit rate of 1.2 Gbit/s using a compact, stable external fibre cavity DFB laser module and a high-electron-mobility transistor (HEMT) front end. A receiver sensitivity of -46.9 dBm and a transmission length of 201.4 km were achieved.
