Mini OTDR K-3300

The entry OTDR done right: a 3.5-inch touch-screen mini OTDR with event map, VFL and optional power meter — dual-wavelength for build work, live-fiber builds for in-service networks.

OTDR, event map, VFL and work light in one 300 g handheld
Four builds: dual-wavelength 1310/1550 at 22/20 dB, or live-fiber 1550 / 1610 / 1625 nm
3.5-inch capacitive touch screen with gesture operation and curve scaling
Event dead zone 3 m, attenuation dead zone 12 m, range to 80 km
Optional power meter (−50 to +26 dBm) and light source
Saves .sor traces and .jpg screenshots; two-trace comparison on board
USB data transfer and remote software upgrade
More than 6 hours per charge

In the box: the parts above, packed per unit. Applications: FTTH installation, acceptance and maintenance testing · In-service (live fiber) monitoring at 1550 / 1610 / 1625 nm · Emergency fault location for access networks.

Choosing a K-3300 Build

For construction and acceptance on dark fiber, the dual-wavelength K-3300D is the build: 1310/1550 nm traces, 22/20 dB of dynamic range for access spans, and a bend check that comes free by comparing the two wavelengths.

On a live network the test wavelength must stay clear of the traffic. Pick the F build your monitoring plan uses — 1550, 1610 or 1625 nm — and the OTDR's hardware and software protection handles the rest.

Need more screen, more range or intelligent event analysis? The K-3500 palm and K-4300 pro platforms share the same logic a step up.
