Cabling for the FED-6944 CWDM Series
The FED-6944 CWDM series use the same rear module as the FED-6944-20/40/80, but require a
different cabling scheme. The supported wavelength is indicated in the card product number. For
example, the FED-6944-27 supports 1270nm wavelengths. If your FED-6944 is a high sensitivity
transceiver, the card product number includes the “H” character. For example, FED-6944-27H.
