Actually it is standard language in the undersea cable world for a large spectrum purchase. Sometimes a fiber pair on a system may be too much, but the buyer still wants many terabits of capacity. "

The Half Fiber Pair is the same as 10*MSUs in a virtual fiber pair, either in C-band or L-band. I believe these are primarily used in transocean routes."


This is what I have learned so far.


Now that deep sea cables are being deployed with as many as 24 pairs, there will be more players doing fractional purchases.

Maybe it's like half a pair of glasses, the perfect accessory for the
one-eyed man who's king.

Seriously though, it sounds like a bad language construction. If a
vendor is offering you that, I'd ask for clarification. Are they
leasing a dedicated strand of fiber end-to-end? Dedicated wavelength
directions delivered by fiber? Something else?

If you're thinking of offering it, find better words.
