Most fusion splicers take 10–30 seconds to boot. The X4+ is ready in 1 second. On a full day of powering on and off across multiple splice points, this adds up to real, measurable time savings — especially on high-volume FTTH rollouts where every minute counts.
The X4+ uses a 4-motor active V-groove drive system to precisely position and align fiber ends before splicing. This delivers consistent ≤0.02 dB SM splice loss across G.652, G.657 (bend-insensitive), and other fiber types — reliable enough for FTTH drop cables, building LANs, and short-distance trunk lines.
The X4+ connects wirelessly to a smartphone app, enabling splice record management, machine status monitoring, and remote control. Ideal for team supervisors overseeing multiple technicians on large FTTx projects — review splice data and machine health without being on-site.
The X4+ features a built-in burglar-resisting system that can lock or disable the machine to prevent unauthorized use. A critical feature for job sites where equipment is left unattended or in high-theft-risk environments.
The rugged 3D protective housing absorbs impact and reduces risk in harsh field conditions — aerial work, tight utility wells, outdoor installations. Built to survive the job site, not just the lab.
Extended field sessions without hunting for a power outlet. The X4+'s large-capacity battery supports 250+ splice-and-heat cycles per charge, covering a full day of intensive FTTH installation work.

The JETFIBER X4+ powers on and is ready to splice in just 1 second — significantly faster than most fusion splicers which take 10–30 seconds to boot. On a busy job site where you're powering the machine on and off frequently, this adds up to meaningful time savings across a full day of work.
Yes. The X4+ supports SM (G.652), MM (G.651), DS (G.653), NZ/NZDS (G.655), and BI (G.657) fiber types. SM splice loss is ≤0.02 dB — well within ITU-T G.652 standards for FTTH and access network applications.
The X4+ connects to a smartphone app via wireless connection, allowing you to view and manage splice records, monitor machine status, and control certain functions remotely. Particularly useful for team supervisors managing multiple technicians on large FTTx rollout projects.
The X4+ uses four motors to drive a flexible V-groove alignment mechanism, which positions and aligns the fiber ends precisely before splicing. This system delivers consistent ≤0.02 dB SM splice loss across a wide range of fiber types and field conditions.
The X4+ features an intelligent burglar-resisting system that can lock or disable the machine to prevent unauthorized use. Valuable for job sites where equipment may be left unattended or in high-theft-risk environments.
The X4+ comes with a 1-year manufacturer warranty plus lifetime maintenance support.
The X4+ differentiates itself with its 1-second boot time, Smart APP connectivity, and anti-theft system — features not found on the COMWAY A33 or TEKCN TC-400. If remote team management and job site security are priorities, the X4+ is the stronger choice. For pure precision at a lower price, the TEKCN TC-400 or COMWAY A33 are solid alternatives.
