Description

K7 Pro fibre fusion splicer with 6 motors and core or cladding alignment: typical loss of 0.02 dB on single-mode, 8 s splice, 18 s heating. 5-inch touch screen, 7800 mAh battery, supplied in a case with cleaver and accessories.

≤ 0.02 dB

Typical single-mode loss, 0.01 dB multimode, 0.04 dB DSF/NZDSF.

8 s · 18 s

8 s splice, 18 s sleeve heating.

6 motors

Core or cladding alignment, automatic focusing.

3-in-1 clamp

Bare fibre, patch cord and drop cable without changing clamp.

7800 mAh battery

240 splice + heat cycles, recharged in 3.5 h at most.

Built-in VFL + OPM

Red laser ≥ 10 mW and power meter −70 to +3 dBm.

3-in-1 clamp: bare fibre, patch cord, drop cable

One clamp for three fibre types

The 3-in-1 clamp takes bare fibre, patch cord and drop cable with no change of accessory: less handling on site.

Fast and easy to read

300× magnification on X and Y: the screen shows splice detection, loss, cleave angle and alerts. 8 s splice, 18 s heating, and a built-in LED for dark places.

300× X/Y display, 8 s splice, 18 s heating, loss as low as 0.01 dB, LED light

18 s heater, automatic or manual mode, preheating

Heating in 18 seconds

The heater shrinks the sleeve in 18 s, in automatic or manual mode, with preheating. It takes 20 to 60 mm sleeves.

A complete touch interface

On the 5-inch touch screen, X and Y views, splice modes, temperature and settings are within reach. The splicer stores 10000 splices and 1000 images.

Interface: X and Y views, splice modes, real-time information, settings

3-in-1 clamp, 8 s splice, 5-inch screen, lithium battery, full kit, VFL + OPM, 6 motors

Splicer in its case with cleaver, Miller pliers, bottle, brush and shoulder strap
