+1 on span along with fiber count designation. On Feb 25, 2016 8:52 PM, "Dave Cohen" <craetdave () gmail com> wrote:
FWIW, at my $dayjob (a fiber-based service provider), the accepted term is "span", which accounts for any continuous segment between add/drop and/or regen locations (i.e. no provider or end user electronics in the middle, only at the endpoints). The most common alternate I come across is "segment". Re a couple of earlier suggestions - A patch between cables to provide continuity, as compared to a fusion splice, doesn't inherently change this view, as it has no bearing on the logical use of the span. Similarly, "strand" isn't favored as it assumes a single fiber only, where the vast majority of applications require a pair (or multiple pairs), so doesn't accurately reflect the logical use of the span. I think "1F Span" is the favored reference for a single-fiber deployment, for the sake of both consistency and clarity.

I have seen: - *fiber circuit* [but also seen used to denote a connection at the network layer over a physical fiber connection. This definition ofcircuitwould include the dark fiber path, the transmitters and receiversandlogicmaking up the data and network layers.] - *fiber loop *[ Does a loop define an electrical circuit with two physically separate positive and negative strands? In that case, isthis aBellhead remnant? ] I am particularly interested in last mile systems, but I don't see any reason that the term wouldn't be the same in the middle mile. thanks, Fletcher -- Fletcher Kittredge GWI 8 Pomerleau Street Biddeford, ME 04005-9457 207-602-1134-- "Genius might be described as a supreme capacity for getting itspossessorsinto trouble of all kinds." -- Samuel Butler-- - Dave Cohen eM: craetdave () gmail com AIM: dCo says
