Palm OTDR K-3500

A palm-size touch-screen OTDR that folds a power meter, light source, VFL and event map into 300 grams — five builds from everyday 1310/1550 testing to live-fiber wavelengths.

OTDR, event map, VFL and work light in one 300 g handheld
Five builds: dual-wavelength 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 2 m, attenuation dead zone 8 m, range to 80 km
Optional power meter (−70 to +6 or −50 to +26 dBm) and light source
Saves .sor traces and .jpg screenshots; two-trace comparison on board
Interchangeable FC / SC / LC OTDR flange; USB data transfer
More than 10 hours per charge

In the box: the parts above, packed per unit. Applications: FTTH and FTTx acceptance testing and fault finding · In-service (live fiber) monitoring at 1550 / 1610 / 1625 nm · Access network installation, maintenance and emergency repair.

Choosing a K-3500 Build

Start with the wavelength. Dark-fiber construction and acceptance work runs on 1310/1550 nm — that is the K-3500D, and its dual-wavelength traces also expose macro-bends by comparing the two. A single-wavelength 1550 unit (K-3515S) covers lighter maintenance work.

Live networks are a different test: the fiber already carries traffic, so the OTDR must measure on a wavelength the traffic does not use and protect itself from the signal. The F builds do exactly that at 1550, 1610 or 1625 nm — pick the wavelength your network plan reserves for monitoring.

Whichever build, the routine is the same: launch fiber on the front, event map for a first verdict, trace for the detail, .sor saved for the record. The optional power meter and light source turn the same box into the loss-test set for sign-off.
