KIFOS2 - Optical Fiber Identifier
The Karvinger KIFOS2 is a professional-grade optical fiber identifier engineered for precise live fiber detection using advanced micro-bending technology. It measures optical power, signal direction, and modulation frequencies (CW/270Hz/1kHz/2kHz) across 850–1700nm, optimized for 1310 & 1550nm. The motorized EasyClamp system provides consistent, hands-free clamping with a single button. Includes a built-in VFL, LED work light, rechargeable battery, and durable field-ready housing.

Questions about this tool
What is an optical fiber identifier used for?
An optical fiber identifier detects a live optical signal — its presence and its direction — without breaking the connection. The KIFOS2 clamps onto the fiber and senses light leaking through the cladding, so you can identify an active fiber without interrupting service.
Can you identify a fiber without disconnecting it?
Yes, and that is the whole point of a fiber identifier. The KIFOS2's non-intrusive clamp reads live traffic and signal direction while the fiber stays in service, avoiding any outage.
What's the difference between a fiber identifier and a visual fault locator?
A fiber identifier like the KIFOS2 detects an existing live signal without disconnecting the fiber, used to trace and identify active fibers safely. A visual fault locator injects its own red laser to find breaks and bad connectors, and needs access to the fiber end. They solve different problems — and the KIFOS2 includes a built-in visual fault locator as well.
What can the KIFOS2 detect?
It detects optical signal presence, transmission direction and modulation frequency (270 Hz to 2 kHz) — enough to distinguish traffic-carrying fibers and recognize the tone signals used to trace a specific fiber.
What is the motorized EasyClamp?
The EasyClamp is a one-button motorized clamp that opens and closes around the fiber hands-free, applying consistent pressure for reliable detection without the technician holding it.
Does the KIFOS2 include other tools?
Yes. It has a built-in visual fault locator and an LED work light, so you can identify a live fiber, locate faults and work inside dark closures with one device.
How is the KIFOS2 powered?
The KIFOS2 has a rechargeable long-life battery, so there are no disposables to replace.
What warranty and shipping come with the KIFOS2?
The KIFOS2 is covered by Karvinger's 2-year limited warranty against manufacturing defects. It ships free express from Karvinger's U.S. warehouses, typically arriving in about 3–4 business days.
