Wioptic offers 50GHz Flat-Top Athermal AWG (Arrayed Waveguide Grating) Module 80ch/88ch/96ch, which is a high-density, passive optical solution designed for ultra-high-capacity DWDM networks. Featuring a flat-top spectral response and 50GHz channel spacing, this module enables precise multiplexing and demultiplexing of 88 wavelengths in the C-band, maximizing fiber capacity while ensuring superior signal integrity.
Engineered with athermal technology, the module operates reliably without active temperature control, delivering excellent thermal stability across a wide operating range (typically -40°C to +85°C). This eliminates the need for power-hungry TEC coolers, reducing power consumption and system complexity—ideal for compact, low-maintenance applications.
The flat-top passband design provides uniform transmission across each channel, offering greater tolerance to wavelength drift and compatibility with high-speed transceivers (100G, 400G and beyond), making it well-suited for next-generation data center interconnects (DCI), 5G transport, metro-access networks, and passive optical systems.
