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.
Functions verified against the ordered version before dispatch — the version table on this page is the exact build list.
Neutral instrument branding as standard; labeling per order.

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.
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.
