Fiber testers from TIFNEX
Testing confirms that a fiber link is within loss budget before you go live. TIFNEX supplies optical power meters, light sources, visual fault locators (VFL) and OTDRs for single-mode and multimode fiber.
Always clean before you test. See fiber cleaners and fiber tools.
Common questions
Power meter or OTDR?
A power meter and light source measure total link loss, which is required for certification. An OTDR shows where along the fiber a fault or splice loss is located.
What is a visual fault locator?
A red laser pen that shows breaks, bends and bad connectors as visible light leaking from the fiber over short distances.
Can you certify our fiber installation?
Yes. Our installation team tests and documents every link.
