4 secSplice time

13 secHeating time

4.3 inchesColor touch screen

3500 mAhBattery capacity

IP5XDust resistance

Key features

4sec

Splicing in quick mode

In SM mode the splice time stays around 5 sec.

13sec

Sleeve heating time

Heating ends quickly and the technician moves to the next splice.

3500mAh

Field battery

Completes 200 splice and heat cycles on a single charge.

6000arcs

Electrode life

Keeps the electrode replacement interval long.

1.384kg

Portable body

The compact body takes up little room in a field bag.

0.03dB

Typical splice loss on single mode

On multimode fiber the typical loss drops to 0.01 dB.

DAY-TO-DAY IN THE FIELD

Dust and rain resistanceIt passes the IP5X dust and IPx2 water tests and keeps working outdoors.

Automatic arc calibrationIt retunes the arc as air pressure and temperature shift.

Result storageIt keeps splice data and images on the unit and transfers them over USB-C.
