Do you certify fiber installed by someone else?+
Yes. Post-install audits, M&A due-diligence testing, and dispute resolution are common — we test, deliver full reports, and identify any strands that don't meet spec so you know what you're working with.
How much does fiber certification cost?+
Roughly $15-$40 per strand for Tier 1 + Tier 2 + inspection on a batch job, with a mobilization fee. Volume discounts on 100+ strands. Emergency and after-hours testing is T&M.
What's the difference between an OLTS and an OTDR?+
An OLTS (Optical Loss Test Set) measures end-to-end insertion loss with a light source and power meter — one number per wavelength per link. An OTDR (Optical Time-Domain Reflectometer) sends pulses down the fiber and measures reflections back, producing a map of every event (splice, connector, break) with distance and loss. Both are required for TIA-568 Tier 2 certification.
Do you clean and inspect connectors during testing?+
Yes — every connector is inspected before mating with a 400x scope, cleaned if needed, and re-inspected. Photos are logged into the closeout report per IEC 61300-3-35.
Do you test with encircled flux for multimode?+
Yes. Our CertiFiber Pro units use encircled-flux-compliant launch conditions per TIA-526-14-B for repeatable and accurate multimode loss measurements.
Can you certify to a specific manufacturer warranty?+
Yes. We are certified installers for Corning, CommScope, Panduit, and Leviton fiber systems and can register 25-year system and application-assurance warranties on qualified installations.
What about high-speed links — 100G, 400G?+
For links approaching optical budget limits or long single-mode spans we add chromatic dispersion (CD) and polarization-mode dispersion (PMD) testing per TIA-455 and manufacturer optics specs. We use Fluke or EXFO test heads for both.
Do you provide re-test after remediation?+
Yes. When links fail, we identify the cause, repair or re-terminate at no extra charge if we installed the plant, and re-test until every link passes. Reports show only the passing final state.
How much does fiber testing cost?+
Fiber Testing pricing depends on drop count, cable type, pathway complexity, and building conditions. Most commercial projects range from $150 to $350 per drop installed. Request a free site survey for an itemized quote.
Do you provide fiber testing nationwide?+
Yes. Access Cabling is headquartered in California with a nationwide technician network for multi-site rollouts across all 50 states.
Is fiber testing certified and warrantied?+
Every installation is Fluke-tested and certified. Structured cabling installs carry manufacturer warranties of up to 25 years through our Panduit, CommScope, Leviton and Belden partner relationships.
