The Swift KF4AV is the top of the All-In-One line: the same five-function active clad splicing platform as the KF4A - stripping, cleaning, cleaving, splicing, and sleeving in one unit - with two built-in test instruments that close the loop on splice quality. An internal Visual Fault Locator drives a 650nm red laser down the fiber to visibly expose breaks, flawed splices, and bad connectors, and an internal InGaAs power meter measures transmission loss so problems get corrected before the cable goes live.

The workflow details earn their keep daily: the thermal stripper (typical 1.5-second strip) eliminates hand-stripping scratches, the single-action cleaver uses a self-rotating blade with a built-in chip collector to keep glass shards off skin, and the one-touch alcohol pump refills easily. Remote maintenance over the Internet keeps the unit tuned without a service trip. Compatible with the full range of industry-standard Fusion Splice-On Connectors (SOC), it is ideal for enterprise, data center, broadband, and FTTH work.
