Precision Splicing for Specialty Fiber
AFL’s ARCMaster FSM-100 Series specialty fusion splicers are built for R&D labs, production environments, and emerging fiber technologies, not standard field splicing. With precise arc control, flexible clamping, and advanced alignment, they handle a wide range of specialty fibers, from polarization-maintaining (PM) and double-clad large-diameter fibers for high-power lasers to newer multi-core and hollow-core designs, giving engineers the control they need for accurate, repeatable splices.
Engineered for Control
Specialty fibers often need alignment tolerances measured in fractions of a micron. The FSM-100 Series pairs moving electrodes with the split V-groove system, so arc control matches each fiber’s diameter. Operators can build, document, and reproduce a splice process, whether on a lab bench or a production line.
Ready for Multi-Core and Hollow-Core Fiber
Multi-core and hollow-core fibers can’t be spliced conventionally. The FSM-100P+ adds the alignment and process control these fibers need.
Multi-Core Fiber: MCF has several independent cores inside one cladding. Each core must align with its matching core, and even a small rotation error can increase insertion loss. The FSM-100P already supports multi-core splicing. The FSM-100P+ combines high-resolution imaging, precise motor control, and rotational alignment to match cores consistently. Its IPA2 alignment algorithm includes multi-core fiber alignment.
Hollow-Core Fiber: HCF guides light through an air-filled core, which can lower latency and reduce nonlinear effects. Its internal structure is sensitive to heat, though, and can deform or collapse if the arc isn’t carefully controlled. HCF also needs precise rotational alignment. Both the FSM-100P and 100P+ let users adjust arc behavior, timing, fiber position, and motion to develop splice settings for each fiber design.
The Competitive Edge
Flexible clamping, no changeovers: The split V-groove system holds a wide range of cladding and coating diameters without swapping V-grooves or clamps.
Arc control matched to the fiber: Motorized electrodes, adjustable fiber height, and electrode oscillation shape the plasma zone for thin, heat-sensitive, and extra-large-diameter fibers.
Alignment for complex fiber structures: EndView observation lets the FSM-100M+/P+ rotationally align photonic crystal, non-circular and other structured fibers.
Accurate PM splicing: FSM-100P+ PANDA mode delivers typical polarization crosstalk of –40 dB/0.6°. IPA mode aligns a wide range of PM fiber types.
Smooth handoff from R&D to production: Advanced arc calibration keeps results consistent when a process moves from the lab to the production floor.
A complete specialty workflow: AFL supplies the whole process, including the SS-110 thermal stripper, CT-111 cleaver, FSM-100 Series splicer and splice protection options.
