Thermal AWGs (Gaussian)


Broadex Technologies' Thermal AWG utilizes silica-on-silicon PLC technology to passively multiplex or de-multiplex up to 96 wavelengths for DWDM bandwidth multiplication over a single fiber.  Thermal AWGs require a heating system and control electronics to keep the PLC device at a constant temperature for optimal operation. This is included with the device and calibrated for immediate deployment.  Broadex Technologies offers a full line of MSA-compatible Thermal AWGs with channel spacings of 50GHz, 75GHz, 100GHz, and 150GHz, covering the O,C, L and E Bands.

A Gaussian AWG is the simplest type of AWG design, where the individual channel passband shape is described by a Gaussian function.  Gaussian AWGs provide the lowest insertion loss out of all AWG types, but require 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
