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! and yea, why not just work with the landindstation operators to use the existing monitoring ports they use? (or get a copy of the monitor ports) -chris ----- End forwarded message ----- -- Eugen* Leitl <a href="http://leitl.org";>leitl</a> http://leitl.org ______________________________________________________________ ICBM: 48.07100, 11.36820 http://ativel.com http://postbiota.org AC894EC5: 38A5 5F46 A4FF 59B8 336B 47EE F46E 3489 AC89 4EC5 -- Too many emails?
