Abstract
Low cost, uncooled, fibre-optic transceiver modules have enabled explosive growth in the use of fiber optics technology in the local area network(LAN). Future trends require modules to work uncooled at higher temperatures (85°C), at higher bit rates (up to 10 Gbit/s), with lower supply voltages (3.3 V), and have small-form-factor (SFF) dimensions for higher port density. DFB lasers, which are required for longer link lengths within the LAN or WAN (wide area network), pose Ihe greatest demands on device design, since the detuning between the DFB Bragg wavelength and the gain peak can change significantly over temperature.
