Professional Fibre, Done Right

AVNFi provides professional fibre optic splicing, termination, and testing for residential and commercial clients across Calgary and surrounding areas. Whether you’re extending an internet hand-off, linking buildings on an acreage, or building structured fibre for a new commercial space, we deliver clean, fully tested, and properly documented fibre infrastructure — the foundation everything else runs on. As a founder-led fibre optic contractor in Calgary, Mark Caya stays hands-on from splice to certification.

What We Do & What We Test

Fusion splicing for single-mode and multimode fibre
Fibre termination and connectorization (LC, SC, and field-installable connectors)
Splice enclosure, tray, and cassette integration
Patch-panel and distribution build-outs
ISP hand-off and demarcation extensions
Point-to-point and campus fibre links between buildings, shops, and outbuildings
Repair and restoration of damaged or degraded fibre runs

OTDR trace testing and fault location
Optical power and insertion-loss measurement
End-face inspection and cleaning to industry standards
Full documentation: splice logs, loss budgets, and as-built records

Residential & Commercial

From a single run into a home office to a multi-tenant backbone, we scale the work to the job — and integrate it cleanly with the rest of your network. Because we also design and deploy full turnkey low-voltage and network systems, your fibre doesn’t end at a panel; it ties straight into a network that’s planned, segmented, and supported.

Why It Matters

Fibre is the part of your infrastructure you don’t want to redo. A bad splice or an untested run shows up as slow links, dropped connections, and expensive call-backs months later. With OTDR testing and certification on every link, you have proof it was done right — and a record you can build on.

Tested and Documented — Every Link

We measure. We don’t guess. Every splice gets an OTDR trace, an insertion-loss reading, and an end-face inspection — logged against a loss budget and handed back as an as-built record. On a recent commercial build we terminated and recertified 650+ drops across a 16-floor hotel, and we run the same standards-compliant process on a single point-to-point link.

Fibre Optic Splicing FAQ

An OTDR (Optical Time-Domain Reflectometer) sends light down the fibre and maps every splice, connector, and bend along the run, with the loss at each point. It proves the link meets its loss budget and pinpoints faults to the metre. We hand you the traces as part of your documentation so you have certified proof the link works.

Yes. We fusion splice and terminate both single-mode and multimode fibre, with LC, SC, and field-installable connectors, and integrate splice enclosures, trays, and cassettes to suit the build.

Yes. We build point-to-point and campus fibre links between buildings, shops, and outbuildings, including directional drilling for building-to-building runs. It ties straight into the rest of your turnkey low-voltage and network build.

Both. We scale the work to the job — from a single run into a home office to a multi-tenant commercial backbone — across Calgary and surrounding areas. Learn more about AVNFi.
