Fiber Splicing

Precision fusion splicing by FOA-certified technicians — every splice tested, every result documented, every closure installed to protect the connection for the lifetime of your network.

Where the Network Comes Together

Fiber splicing is the most technically demanding element of fiber optic construction — and the one where quality has the most direct impact on network performance. A single poor splice on a critical fiber can introduce signal loss that compounds across the entire span.

Axiom Fiber Optics's splicing teams hold FOA Certified Fiber Optic Technician (CFOT) credentials and are trained on the latest core-alignment fusion splicers. We maintain strict quality standards: every splice is inspected, every result is measured with an OTDR, and any splice that doesn't meet spec is re-done — period.

Fusion Splicing

Fusion splicing is the gold standard for permanent, low-loss fiber connections. By precisely aligning two fiber ends and fusing them with an electric arc, a properly executed fusion splice introduces virtually no measurable optical loss — making it ideal for long-haul routes, high-density networks, and any application where signal performance is critical.

  • Single-fiber fusion splicing — all fiber types (SM, MM, DS, NZDS)
  • Mass fusion splicing for high-count cables (ribbon fiber)
  • Core-alignment splicers for lowest possible loss
  • Average splice loss target: <0.05 dB per splice
  • Heat-shrink protection sleeves on every splice
  • Splice tray organization and labeling

Mechanical Splicing

Mechanical splicing provides a fast, tool-light connection method for situations where fusion equipment isn't available or practical — emergency restorations, temporary repairs, and locations where power access is limited. While mechanical splices introduce slightly higher loss than fusion, they are a reliable solution when speed or accessibility is the priority.

  • Field-installable mechanical splices — all fiber types
  • Ideal for emergency and temporary restoration
  • No power required for splice machine
  • OTDR-verified post-splice
  • Convertible to fusion splice when permanent access is available

OTDR Testing & Acceptance

Every completed splice point is verified with an Optical Time-Domain Reflectometer (OTDR). OTDR traces show the exact optical signature of every event on the fiber — splices, connectors, bends, and faults — so you know precisely what you have before the closure goes on.

Axiom Fiber Optics provides full OTDR documentation in both native instrument format and printed/PDF splice records — organized by fiber, buffer tube, and cable segment for easy future reference. Our test records are accepted by all major telecom carriers and broadband program administrators.

  • Bidirectional OTDR testing on every fiber
  • End-to-end loss measurements (OLTS)
  • Individual splice loss recorded and reported
  • Splice records in PDF, SOR, and customer-preferred formats
  • As-built splice diagrams included
  • Carrier-acceptable test packages for network acceptance

Splice Closure Installation

The splice closure is the long-term home of every splice point on your network — it needs to be installed correctly the first time. Axiom Fiber Optics installs dome, horizontal, and inline splice closures from all major manufacturers, with proper gel or heat-shrink sealing, pressurization ports where required, and complete fiber tray organization.

  • Dome, inline, and horizontal closure types
  • Underground vault, aerial, and aerial lashing mounting
  • Gel and heat-shrink sealing methods
  • Pressure test after sealing (where applicable)
  • Cable clamp and strain relief installation
  • Closure location documentation and marking

Emergency Fiber Restoration

Fiber cuts happen. When they do, every minute of outage has a cost. Axiom Fiber Optics offers 24/7 emergency splicing response — our on-call crews can mobilize within hours with all necessary equipment to restore severed fiber as quickly as possible.

  • 24/7 emergency response capability
  • Fault location using OTDR prior to excavation
  • Mechanical and fusion restoration options
  • Temporary bridging cable installation if required
  • Permanent restoration follow-up scheduling

Our Quality Standard

Axiom Fiber Optics will not deliver a splice that doesn't meet spec. If an OTDR trace shows a splice above our loss threshold, we re-splice it before closing — no exceptions, no negotiating on quality. The extra time it takes upfront is always less than the cost of a future outage.
