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. ________________________________ From: William Herrin <bill@herrin.us> Sent: Tuesday, January 26, 2021 10:56 PM To: Rod Beck <rod.beck@unitedcablecompany.com> Cc: nanog@nanog.org <nanog@nanog.org> Subject: Re: Half Fibre Pair On Tue, Jan 26, 2021 at 12:52 PM Rod Beck <rod.beck@unitedcablecompany.com> wrote:
Can someone explain to me what is a half fibre pair? I took it literally to mean a single fibre strand but someone insisted it was a large quantity of spectrum. Please illuminate.
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. Regards, Bill Herrin
