Pro OTDR K-4300

The pro-tier platform: a 4.3-inch touch OTDR with intelligent link analysis, eight builds to 32 dB and 150 km — including multimode and triple-wavelength versions.

Eight builds: multimode 850/1300, dual-wavelength to 32/30 dB, triple-wavelength, and four live-fiber models
4.3-inch touch screen — trace, event map and event list on one linked screen
Intelligent link analysis: connectors, splices, flanges and macro-bends identified automatically
Event dead zone 1 m, attenuation dead zone 5 m, range to 150 km
Pass/fail thresholds; up to four traces compared on screen
Optional power meter (−50 to +26 dBm, 9 calibration wavelengths) and light source
8 GB memory, .sor and .jpg saving, user interface in 7 languages
More than 10 hours per charge; works from −20 °C to +50 °C

In the box: the parts above, packed per unit. Applications: Access, metro and backbone construction acceptance · FTTH / PON maintenance and in-service monitoring · Multimode premises and data-center link certification (K-4300M).

Choosing a K-4300 Build

Match dynamic range to span: 28/26 dB covers most access and FTTH work; the 32/30 dB K-4300D-32 is the long-haul and high-splitter-ratio choice. The K-4300T adds 1625 nm on the same unit for bend-sensitive checks, and the K-4300M is the multimode build for 850/1300 nm premises fiber.

The F and N builds are for live networks — wavelengths and filtering chosen so the OTDR can measure while traffic runs, with an in-line optical alarm and module self-check protecting the instrument.

Every build shares the same screen logic: event map for the picture, trace for the proof, event list for the numbers. Crews trained on one K-4300 are trained on all of them.
