Fiber Optic Splicing
Precision fusion and mechanical splicing for single-mode and multimode networks — low-loss terminations, high-count ribbon work, and OTDR-verified documentation that closes out the first time. The foundation of every reliable fiber build.
Every Network Is Only as Good as Its Splices
A fiber route is a chain of splice points, and each one is a place where loss, reflectance, or a sloppy closure can quietly erode the link budget you engineered for. On a long backbone or a dense FTTH build, the difference between a splice held at 0.05 dB and one drifting toward 0.3 dB compounds across every segment — and shows up later as marginal links, intermittent faults, and acceptance-test re-work.
CoreSync treats splicing as the precision work it is. We run core-alignment fusion splicers, verify our work with bi-directional OTDR traces rather than trusting the machine's estimate alone, and re-splice anything out of spec before the closure is sealed. The result is a fiber plant that performs the day it's certified and stays inside budget as it ages.
Whether you're a carrier extending backbone, an ISP pushing last-mile, or a general contractor who needs skilled splice-crew capacity to keep a deployment on schedule, we integrate into your workflow and your documentation standards — not the other way around.
What You Can Expect

- Low-loss splices verified inside carrier budgets
- Bi-directional OTDR certification on every segment
- As-built splice matrices and trace documentation
- Crew capacity that scales with your deployment
Full-Spectrum Splicing & Termination
Single-Mode & Multimode Fusion
Core-alignment fusion splicing for OS2 single-mode and OM3/OM4/OM5 multimode fiber, with typical splice loss held well inside carrier loss budgets.
Ribbon & Mass Fusion
12-fiber ribbon and mass-fusion splicing for high-count backbone cable — the throughput modern 432- to 864-count builds demand without sacrificing splice quality.
Connectorization & Termination
Field and pigtail termination, fusion-spliced connectors, and pre-terminated assembly integration for clean, repeatable end-face performance.
Splice Closure & Sealing
Aerial, pedestal, vault, and direct-buried closure installation — gel and heat-shrink sealing, splice-tray management, and re-entry-ready slack storage.
Mechanical & Quick Restoration
Mechanical splices and field-installable connectors when a temporary or rapid restoration is the right call before a permanent fusion repair.
Documented As-Builts
Every splice point traced and recorded — splice matrices, tray maps, and OTDR-backed loss records that hold up to carrier acceptance review.
From Cable Prep to Signed-Off Segment
Scope & Prep
We review your splice matrix, cable counts, and closure specs, then stage fiber, prep cable ends, and clean the work area to manufacturer standards before the first splice.
Splice & Close
Core-alignment fusion with real-time loss estimates at the machine, organized into trays with correct bend radius and slack, then sealed in a properly torqued, re-entry-ready closure.
Test & Certify
Bi-directional OTDR traces and insertion-loss readings confirm every splice is inside budget. Out-of-spec splices are re-done on the spot — not signed off and left for the next crew.
Document & Hand Off
You get as-built splice matrices, tray maps, and trace files in the format your acceptance process requires, so the segment closes out clean the first time.
Splicing for Every Phase of the Build
Splicing isn't a single moment in a deployment — it runs from the first backbone segment through last-mile distribution and into the maintenance years that follow. CoreSync supports all of it, scaling crew capacity to match your schedule.

Frequently Asked Questions
What fiber splicing methods does CoreSync use?
Core-alignment fusion splicing for single-mode and multimode fiber — including ribbon and mass fusion for high-count cable — plus mechanical splices and field-installable connectors for rapid or temporary restoration.
What splice loss can I expect?
We hold splices well inside carrier loss budgets and verify every one with bi-directional OTDR rather than trusting the splicer's on-screen estimate. Anything out of spec is re-spliced before the closure is sealed.
Do you splice in the field and in all closure types?
Yes — aerial, pedestal, vault, and direct-buried closures, with proper splice-tray management, bend radius, slack storage, and re-entry-ready sealing.
Do you provide splice documentation?
Every splice point is traced and recorded. You receive as-built splice matrices, tray maps, and OTDR trace files in the format your acceptance review requires.
Can you provide overflow splice-crew capacity on a deadline?
Yes. CoreSync regularly supplies subcontract splice-and-test capacity to prime contractors and carriers, scaling crews to keep a deployment on schedule.
