Common use of Optical WDM Grid Clause in Contracts

Optical WDM Grid. 3 CFP MSA modules may operate within specific WDM (wavelength division multiplexed) grids. It is 4 recommended that CFP MSA modules adhere to the ITU-T WDM grid conventions. 5 The ITU-T document G.694.1 specifies the DWDM frequency grid anchored to 193.1 THz. It supports a 6 variety of channel spacing of 12.5, 25, 50, 100 GHz and wider. 8 The ITU-T document G.694.2 specifies the CWDM wavelength grid, which supports a channel spacing 9 of 20 nm. Unlike DWDM, whose grid is specified in terms of an anchor frequency, the CWDM grid is 10 defined in terms of wavelength separation. This grid is made up of 18 wavelengths defined within the 11 range 1271 nm to 1611 nm.
