48-CH 100G Athermal AWG

48-CH 100G Athermal AWG

This 48-Channel 100GHz Athermal AWG (Arrayed Waveguide Grating) module provides high-density wavelength multiplexing and demultiplexing with excellent thermal stability. Designed for operation in the C-band based on the ITU grid, it ensures low insertion loss, high channel isolation, and reliable performance without the need for external temperature control.

Ideal for DWDM transmission, wavelength routing, and optical add/drop multiplexing, the module supports 48 channels with precise wavelength accuracy. Its compact and robust design guarantees consistent operation across a wide range of environmental conditions. Custom configurations including channel count, spectral profile, connector type, and packaging are available to meet specific system requirements.
