Fusion Splicer K-V1

The trunk-line splicer built for pace: core alignment, a 6–10 second splice with typical single-mode loss of 0.02 dB, a 4.3-inch touchscreen, and a 5,200 mAh battery good for more than 250 splice-and-heat cycles per charge.

Core alignment with dual 90° cameras: X, Y and combined X/Y views at up to 380× magnification — the fibers are centred on their cores and checked on screen before every arc, which is how the machine holds typical loss to 0.02 dB on single-mode fiber
A 6–10 second splice and 15–30 second heat: the cycle pace a trunk crew works at, joint after joint, with the loss estimate shown for every splice
The arc calibrates itself: discharge power adjusts automatically to air pressure and temperature, so joints stay consistent from a valley floor to a site at 5,000 m, in wind up to 15 m/s
4.3-inch color touchscreen with physical buttons as well — operate it the way the job demands, with two high-power LED work lights and blue backlit keys for night and cabinet work
A full day on one charge: the 5,200 mAh battery runs more than 250 splice-and-heat cycles, and the electrodes are rated for 5,000 discharges before they need changing
Records that stay with the job: 10,000 splice results and 10,000 splice images stored on the machine, with 41 preset splice modes and room for 100 of your own, exported over Mini USB 2.0
Private labeling made to your requirements — labels with your logo, part numbers and barcodes on the inner boxes and outer cartons, ready for your warehouse

How It Works — core alignment and an arc that follows the weather

Alignment decides the splice before the arc fires. The two fibers rest in the V-grooves and the dual cameras watch them from two axes at 90° to each other; the machine centres the fibers on their cores in the X view, the Y view or both together, magnified up to 380× on the touchscreen, so any offset is visible and corrected before the discharge — the routine that keeps typical loss at 0.02 dB on single-mode and 0.01 dB on multimode.

Then the arc takes over, and it does not fire blind. The machine reads the air pressure and temperature around it and calibrates the discharge to the conditions — thin air at altitude and a hot afternoon both change how an arc behaves, and the calibration follows them, which is what makes joint number forty on a mountain repeater site match joint number one in the yard.

Every joint leaves proof. The machine estimates the loss of the splice it just made, proof-tests the joint at 1.96–2.25 N, and stores the result with its splice image — 10,000 of each on the machine, ready to come off over Mini USB for the job file.

Housekeeping is the accuracy budget: keep the V-grooves, clamps and lenses clean, watch the electrode count — a set is rated for 5,000 discharges — and let the automatic calibration run when the weather turns, and the machine repays it with consistent joints.
