I never heard of this but wanted to ask some experts. A security company spoke to the owner of our company today about implementing IP Cameras. These cameras would have their own switches in the wiring closets, but need a fiber connection back to our server room. He said that it is possible to split the fiber connection so the two seperate networks can share the fiber backbone.
Is this possible? Do they use different frequencies? If this is possible how does this affect bandwidth?
Thanks for the ratings.
DWDM/CWDM is like a two-edged sword. For a small fee (the procurement of the modules and the circulator) you can split/splice one physical fibre optic cable into multiple pairs. The downside is that once you loose your one-and-only fibre link (to a cable-hunting-buck-hoe) then you're in trouble.
It's called Coarse Wave Division Multiplex (CWDM) or Dense Wave (DWDM).
