I have been under the impression for years now that the age of the fiber may play a roll in which you prefer due to channel spacing needed to cram in more frequencies. Never really came across a real world situation where one didn't work as well as the other. There is probably more things to consider than the fiber's age. Thank You Bob Evans CTO
Hello,
fs.com offers DWDM optics that are cheaper than CWDM optics: CWDM 80km 10G for 600$ http://www.fs.com/c/cisco-cwdm-sfp-plus-2425?70-80km DWDM 80km 10G for 420$ http://www.fs.com/c/cisco-dwdm-sfp-plus-2485?70-80km
This is significant. Is this for real? Has anybody bought their DWDM optics?
Going with DWDM and passive Mux/Demux seems to be cheaper nowadays than going with CWDM.
