Hahaha, a salesman. Should have known.
No sales person in Telecoms ever actually understands how the kit operates. The amount of times we have to clean up the mess left by "Technical sales
staff" miss selling stuff to customers is unreal....
Again, your confusing capacity with individual link bandwidth. We have a 3.6 Tb system in place on our network, but is made up of hundreds of STM-64
links, all using DWDM. The 3.6Tb refers to the total capacity of the system, not the individual bandwidth provided by each wavelength. Each wavelength
is a single link in it's own right. All DWDM does is push multiple wavelengths down a fibre instead of just the one in standard SDH transmission.
Seriously, you might think you know DWDM, but you clearly have bugger all understanding of SDH/SONET transmission, which is needed to even begin to
actually know how DWDM operates....
EDIT: And no, I don't deal with Metro networks or even IP (uurrgh). I currently work for a large Telco in the UK managing a national transmission
network with international links.
I am qualified and experienced on Marconi and Nortel equipment, including SMA series and TN series multiplexors, plus the Marconi 1664 DWDM equipment,
which we utilise in our core network. I also have a solid background in Nortel DMS switches.
The guys over the way from me manage the international network, including these very cables this thread is about.
