GIGALIGHT Launches 75GHz Flat-top AAWG DWDM

Shenzhen, China, March 9, 2022 – GIGALIGHT’s subsidiary, GROWSFIBER (a high-quality passive component manufacturer), today officially announced the launch of a 64-channel 75GHz flat-top AAWG DWDM, which perfectly supports 400G DP-16QAM coherent optical transmission and meets the high bandwidth requirements of Data Center Interconnection (DCI) optical networks.

The 75GHz flat-top AAWG DWDM of GROWSFIBER features:

  • 64 DWDM channels of CH1-CH64 with center wavelength from 1566.621nm to 1528.871nm (191.3625THz to 196.0875THz)
  • Insertion loss of less than 5dB (better than the ODCC requirements of less than 8.5dB)
  • Ripple of less than 0.3dB, providing sufficient margin
  • Wavelength shift of ±0.05nm assured by optimized screw temperature compensation process
  • Channel uniformity of less than 1.5dB (better than the ODCC requirements of less than 2.5dB)
