Broadex Technologies' Athermal Arrayed Waveguide Grating (Athermal AWG) is a fully passive device that requires no electrical power for thermal stabilization and are ideally suited for use in applications where no power is available. The Athermal AWG utilizes silica-on-silicon PLC technology to multiplex or de-multiplex up to 96 wavelengths for DWDM bandwidth multiplication over a single fiber.  Broadex Technologies offers a full line of MSA-compatible Athermal AWGs with channel spacings of 50GHz, 75GHz, 100GHz, and 150GHz, covering the O,C, L and E Bands; and the devices are optimized for use in Central Office temperature applications (c-temp) and or Remote Node temperature applications (i-temp).

A Gaussian AWG is the simplest type of AWG design where the individual channel passband shape is described by a Gaussian function.  The Gaussian AWGs provide the lowest insertion loss out of all AWG types, but requires tighter tolerances on other system components in order to ensure the peak of the Gaussian curve stays within the passband over the full operational temperature range.
