We demonstrate 2-Gb/s data transmission through a 5-km-long standard single-mode fiber by using a GaAs-based 1.2-μm GaInAs-GaAs quantum well laser. The fabricated laser exhibits a high characteristic temperature of 140 K. The results indicate the possibility of Gigabit/s local area networks (LANs) using uncooled lasers (possibly surface-emitting lasers) operating at a 1.2-μm wavelength band.
