Questions about this tool
What is the difference between core alignment and cladding alignment fusion splicers?
Core alignment actively lines up the light-carrying cores of the two fibers using cameras and motorized positioning, while cladding alignment only aligns the outer glass. Core alignment produces lower, more consistent splice loss, which is why professional FTTH and backbone work requires it. The KEFOK6 is a true 6-motor core-alignment splicer.
What splice loss should a good fusion splicer achieve?
A quality core-alignment splicer achieves typical splice loss of 0.02 dB or lower on single-mode fiber. The KEFOK6 meets that 0.02 dB figure and aligns across SM, MM, DS and NZDS fiber types.
How long does a fusion splice take?
On the KEFOK6, a splice completes in about 6 seconds and the heat-shrink cycle in about 16 seconds. A single charge covers roughly 240 splice-and-heat cycles — about a full day in the field.
Do I need a separate power meter and fault locator?
Not with the KEFOK6. It has a built-in optical power meter (−70 to +6 dBm) and a visual fault locator, so you can splice, verify the link and locate faults with one device instead of carrying three.
What's included in the box?
The KEFOK6 ships as a complete field kit: the splicer, a high-precision cleaver, spare electrodes, a fiber stripper and a rugged aluminum carrying case — ready to use out of the box.
Are consumables like electrodes replaceable?
Yes. The KEFOK6 uses replaceable electrodes, and spares are included in the kit.
Do you offer bulk pricing or purchase orders for businesses and schools?
Yes. Karvinger supports PO-based purchasing for professional and institutional buyers, with volume pricing starting at 5 units and net terms available on approval — useful for ISPs, contractors and training programs equipping multiple stations.
What warranty and shipping come with the KEFOK6?
The KEFOK6 is covered by Karvinger's 2-year limited warranty against manufacturing defects. It ships free express from Karvinger's U.S. warehouses, typically arriving in about 3–4 business days.
