Athermal AWG for Higher Baud rate DWDM system
75GHz spacing Athermal AWG
This AWG is compatible with the 0.6nm wavelength (75GHz optical frequency) spacing DWDM system, which is being developed for Data Center Interconnect.
In the large capacity communication system that is optimized the modulation speed and wavelength allocation simultaneously, extremely wide bandwidth is required to the multi / demultiplexer.
Our 75GHz-spacing AWG achieves wide bandwidth with a ratio of 1dB-band-width to channel-spacing of 0.66.
Expandable up to 64channels, we can cover the C-band wavelength range with one module.
