Fusion Splicers

K-63 Fusion Splicer

Precision is a sequence — a clean cleave, an exact presentation, then the arc. The K-63 four-motor fusion splicer holds that sequence at a typical single-mode loss of 0.03 dB, with a 6-second SM FAST splice and a V-type heater whose removable 5-in-1 fixture adapts to the sleeve in hand.

Motor drive: Four-motor
Applicable fibers: SM (G.652) / MM (G.651) / DS (G.653) / NZDS (G.655) / BI (G.657), single fiber
Compatible fiber / cable: 0.25–3.0 mm; indoor cable
Coating diameter: 0.125–1 mm
Cleave length: 8–16 mm

Key features

Built around the cleave-to-arc sequence: fibers are presented by a multi-function clamp that lifts out freely for cleaning, viewed at 400× in X, Y or combined X/Y, and joined only when the presentation is exact
Four-motor drive, 6-second splicing in SM FAST mode, and a loss estimate for every joint — typical loss 0.03 dB on single-mode, 0.02 dB on multimode and 0.03 dB on G.657 bend-insensitive fiber
The V-type heating tank is preset for five sleeve lengths (20–60 mm); its 5-in-1 fixture removes and re-seats at the back of the machine, so one fixture serves the range of work a crew meets in a day
Heating time adjusts from 10 to 900 seconds, with a typical cycle of 20 seconds or more — the shrink follows the sleeve in use, not a fixed timer
Automatic ARC calibration reads air pressure and temperature and resets the discharge to the conditions, holding precision from −20 °C to +50 °C and at altitudes up to 5,000 m
A 4.3-inch touchscreen with physical buttons as well, 3 powerful white LEDs for cabinet and night work, and a 5,200 mAh battery rated for typically more than 250 splice-and-heat cycles; electrodes serve 5,000 arcs
The record is part of the precision: 20,000 splice results and 200 splice images stored on the machine, 41 preset splice modes with room for 100, exported over Mini USB 2.0
Supplied neutral as standard, or 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
