Notes:* Per ITU G.694.2; wavelength spacing = 20nm, 1270 - 1450 nm also available
**Some vendors use these "codes," to describe the wavelengths.
These codes are the middle digits of the wavelength-not "channel numbers."

Example: FDCW00214701110
This gives you CWDM 1x2 Filter, Center Wavelength of 1470, 250um fiber with no connectors.
