Fiber overlashing services add new optical fiber cable to existing aerial strand by lashing it alongside cable already in place, instead of installing a new strand and going through a full make-ready and attachment cycle. It is a common method for overbuilding fiber-to-the-home networks, adding backbone capacity, or bringing a second carrier onto plant that already has strand rated for the extra load. Fiber Construction Company provides fiber overlashing services nationwide as an extension of its aerial construction work, coordinating with pole owners and joint-use agreements so the added cable meets clearance and loading rules.
What Fiber Overlashing Involves
Overlashing attaches new fiber cable to an existing aerial strand using an overlash wire wrapped around both the strand and the new cable in a spiral pattern. The technique lets a second, or third, cable ride the same support structure already anchored to the poles, which can reduce the need for new pole attachments on routes where the strand still has spare loading capacity. It is used for network overbuilds, adding redundant paths, and bringing new fiber to a corridor where a carrier already has plant in place. It is not a substitute for new strand construction on routes that are already at capacity or where clearance to power, communications, or ground is tight.
How Fiber Construction Company Delivers It
Fiber Construction Company plans and manages overlashing work through insured subcontractor crews operating under its oversight, using bucket trucks, aerial lifts, and lashing machines rated for the span lengths and cable types involved. Before crews mobilize, the strand and existing attachments are reviewed for loading capacity, sag, and clearance so the added cable will not put the pole or strand out of compliance. Crews coordinate with pole owners and other attachers where required, follow the engineering package for the route, and document completed spans as work progresses. The same crews and processes used for aerial fiber construction carry over to overlashing, so a build that starts as new strand and later needs added capacity can move to overlashing without switching contractors.
Overlashing Methods and Scope
Crews use lashing machines that spiral wire around the strand and cable as they travel the span, which is standard for production runs on longer routes. Shorter or irregular spans, drop points, and tie-ins near splice enclosures are handled with hand lashing where a machine cannot safely operate. Work includes managing mid-span slack, maintaining bend radius at pole attachments, and setting up traffic control where the route runs along roadways. Fiber Construction Company handles overlashing across rural long-haul routes, suburban distribution plant, and urban corridors, and can scope a project as overlash-only or combine it with new strand construction on segments that need it.
What Buyers Should Know Before Hiring
Overlashing lowers cost and shortens schedule compared to new strand construction, but it still depends on an accurate read of the existing plant. A strand loading and clearance review should happen before bidding, since undersized or already-loaded strand can turn an overlash job into a make-ready project mid-build. Some pole owners require notification or a permit even when no new attachment is added, so permitting should be confirmed early rather than assumed. Overlashed cable still needs splicing and testing at each tie-in point, and buyers should plan for that work as part of the same project rather than a separate contract. Fiber Construction Company scopes these items up front so the bid reflects the actual condition of the plant.
Fiber Overlashing Services, answered
What is fiber overlashing?
Fiber overlashing is the process of attaching a new fiber cable to an existing aerial strand by spiraling a wire around both, rather than installing a separate strand. It lets a route carry additional cable without a full new attachment cycle, as long as the existing strand has enough spare loading capacity for the extra weight.
Does overlashing avoid pole make-ready?
Overlashing often avoids the need for a new pole attachment, but it does not automatically avoid make-ready. If the existing strand or clearance is already near its limit, the added cable can trigger the same loading and clearance work a new attachment would require, so a capacity review before bidding matters.
How is overlashing different from new aerial construction?
New aerial construction installs a new strand, new attachment hardware at each pole, and new cable. Overlashing reuses strand that is already in place and adds cable to it. Overlashing is generally faster and less expensive, but only works where the existing strand has spare capacity and acceptable condition.
Can any pole or strand be overlashed?
No. The existing strand needs enough rated capacity for the added cable weight, acceptable sag and clearance, and, in many cases, sign-off from the pole owner or other attachers. Fiber Construction Company reviews strand condition and loading before committing to an overlash scope instead of new construction.
Does the overlashing project include splicing and testing?
Overlashing covers the physical attachment of cable to strand. Splicing at tie-in points and end-to-end testing are separate work that Fiber Construction Company scopes alongside the overlash build so the added fiber is turned up and verified rather than left as an unspliced run.
