Standard terminology for a dark fiber path?
What is the standard terminology for strands of dark fiber spliced together to form a continuous path between points A and Z? I have seen: - *fiber circuit* [but also seen used to denote a connection at the network layer over a physical fiber connection. This definition of circuit would include the dark fiber path, the transmitters and receivers and logic making 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, is this a Bellhead 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

What do you call it if it is made out of copper instead of glass? Or air? I don't see anything wrong with "fiber path". (Answering my own question, maybe: "dry pair from A to B". "[Microwave] Radio link between A and B.") -- sed quis custodiet ipsos custodes? (Juvenal)
Just my .02 but I would think to call it a "single fiber link" or perhaps just a "fiber link". A fiber path doesn't strike me as being one solid connection but could instead include patching in the middle and not be a continuous strand. As far as fiber loop, that is used to reference the OC192 transport ring that exists in the DC metro area. Again, this is just from my experience but I find people misusing terms all the time so I've come to accept that I need to always ask qualifying questions to determine what they truly mean.

IDK what elsewhere uses but strand or (less common) span is the common term I've seen specifically for a passive piece of glass between two points. On Wed, Feb 24, 2016 at 12:55 PM, Fletcher Kittredge <fkittred@gwi.net> 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. On Thu, Feb 25, 2016 at 6:27 PM, Michael Loftis <mloftis@wgops.com> wrote:

+1 on span along with fiber count designation. On Feb 25, 2016 8:52 PM, "Dave Cohen" <craetdave@gmail.com> wrote:

As Dave C pointed out, it commonly referenced as a Fiber Span. The fiber span would be inclusive of any splice points and/or patches needed to provide connectivity between point A and point Z. A Fiber Stand is a single piece of glass within the cable sheath, often spliced to create a fiber span. A Dark Fiber Circuit commonly refers to the service/product that was sold by or bought from a Service Provider. The Dark Fiber Circuits are turned over to the customer as a fiber span between point A and point Z. It should also be noted that the span can consist of 1 fiber or a pair of fiber. It is common for service providers to us "Bi-Di" optics, allowing the use of 1 fiber for transmit and receive between their equipment.
