I have been looking at the page "Cisco Enhanced Wavelength Division Multiplexing Product Line", on Cisco's web site. I would like to light up some dark fibre for at least 2x 10Gbps Ethernet links. Looking at that page, can I use the eDWM box (EWDM-OADM4) on it's own to get 4x10Gbps links over a dark fibre pair, or do I need to have both boxes at both ends (EWDM-OADM4 & CWDM-MUX8A)?
Also, not having done this before; I have looked around and found tuned DWDM X2 optics such as 10GDWDM-X2-38.98=, (SFP+ devices also exist that are tuned to DWDM frequencies like this). Should these "just work" when connected directly into the eWDM mux above and a switch of my choosing (that supports the chosen transeciever type be it SPF+ or X2)? I assume the IOS will be ignorant of the SFP+/X2 being tuned, that is the point of them, and they will function like normal?
