From the site: Problem - federal integrator with a government customer needed to connect geographically dispersed antenna sites to a central pool of monitoring equipment.

Our Solution - With Glimmerglass managing the reconfiguration of optical signals, the integrator was able to create an RF-over-fiber solution that performed better and cost less than traditional implementations. .. I would be *REALLY* interested in seeing how they did this. We've been doing this (it's called Fiber IFL) for a long time, but the range with nearly everything has been sub 40km for the most part. Getting geographically diverse sites all linked up via rf to fiber would be a nightmare unless you were planning on demodulating the signals and sending them via IP, which wouldn't surprise me.

this involved, I think, just intuiting signals from the nearfield effects of the cable, no? 'drop a large sensor ontop-of/next-to the cable, win!'

this I thought included the capabilities to drag the fiber/line into the hull for 'work' to be done... I'd note that introducing signal loss on the longhaul fiber seems 'risky', you'd have to know (and this isn't hard I bet) the tolerances of the link in question and have a way to stay inside those tolerances and not introduce new splice-points/junctions/etc and be careful for the undersea cable power (electric) requirements as well.

fun stuff!

Fun stuff indeed...sell to one org or the other: http://www.glimmerglass.com/solutions/submarine-cable-landing-stations/ http://www.glimmerglass.com/solutions/cyber-security-and-lawful-intercepti on/
