Crew Capabilities
Seralex splice crews operate from staging locations in Charlotte, Richmond, and Northern Virginia, positioning equipment for same-week mobilization to job sites across our coverage area.
Crews carry:
- Sumitomo fusion splicers for production work,
- mechanical splice kits for emergency field repairs when a temporary connection is needed before permanent restoration.
Post-splice verification uses Viavi T-BERD 2000 and EXFO FTB-1 OTDR (Optical Time-Domain Reflectometer) platforms on every completed joint.
OSP and FTTH Splicing Capabilities
Fiber Types, Cable Counts, and Splice Locations
Seralex performs underground fiber splicing for singlemode (SM), multimode (MM), and ribbon fiber on new network builds, capacity expansions, and FTTH deployments. Crews splice cables from 2-count through 432-count across all project types. Ribbonizing loose tube cable for mass fusion splicing is available on high-count projects.
Splice locations include:
- fiber distribution hubs (FDH)
- network interface devices (NID)
- pedestals
- underground vaults
- cabinets
- field-mounted splice enclosures
Crews access each location type as part of the project scope, whether the build requires a backbone route with high-count ribbon cable or an FTTH distribution network with singlemode drops at every pedestal.
Splice Quality and Construction Alignment
On singlemode fiber, Seralex crews achieve splice loss below 0.1 dB as a production standard, verified by OTDR trace on every completed splice. That metric replaces vague quality promises with a number ISP engineers can hold us to.
Because Seralex also builds the underground conduit infrastructure through our HDD service line, splice crews work on routes we constructed, a turnkey advantage rare among fiber splicing companies.
Alignment between construction and splicing teams eliminates the rework that occurs when a splice contractor encounters undocumented conduit runs, unexpected cable routing, or incomplete as-built records from a separate construction vendor.
Testing, Documentation, and Quality Assurance
Every splicing project closes with verified test data and documentation delivered to the client.
OTDR testing confirms splice loss, connector loss, and end-to-end link performance. Where project specifications require it, bi-directional OTDR testing and insertion loss verification using a calibrated optical loss test set (OLTS) are performed as additional quality checks.
Closeout deliverables include:
- splice reports with individual splice loss values, trace files, and cable identification data
- as-built documentation recording cable routing, splice closure locations, and fiber assignments for the client's network records
Completed splices are sealed in enclosures rated for underground installation, protecting fiber joints against moisture, soil pressure, and temperature cycling over the life of the network.
Emergency Splice Repair
When a cut or bore strike takes a route down, Seralex splice crews respond from the same staging points used for production work.
Mechanical splicing restores traffic fast as a temporary fix; permanent fusion splicing and full OTDR verification follow once conditions allow production-quality work. Every truck carries both mechanical kits and fusion splicers, so a single dispatch covers either scenario.
Full 24/7 emergency restoration, SLA-backed response, and combined preventive maintenance are covered on the fiber maintenance and restoration page.

Yes. Seralex performs underground conduit construction, fiber pull, fusion splicing, and testing under a single contract. We call this Path to Plug: one contractor carries the project from conduit in the ground to lit fiber at the subscriber, with last-mile installation included when the scope requires it. One schedule, one set of as-built records.
