Fitel S184 Fiber Fusion Splicer with Ring of Fire® Technology
The S184 3-Phase Wide Area Plasma Splicer series includes groundbreaking technology that separates it from all other fusion splicers. In a standard fusion splicer, the heat source is a plasma generated by an electrical discharge between two electrodes. The fi bers being fused are directly exposed to the plasma fi eld with a very narrow heat zone. The heat zone produced is very narrow - the temperature can drop
dramatically only 200um from the arc center. Furthermore, 2-electrode systems have a maximum practical fiber diameter of 500um, due to the limited spatial extent of the plasma.
Conversely, the S184 3-Phase Wide Area Plasma Splicer has three electrodes in a “T” configuration. This 3rd electrode combined with an advanced self-balancing arc discharging unit (ADU) allows for a significantly more stable thermal profile where radiation is the primary means of heat transfer to the spliced fibers. This resulting heat zone cross-section is significantly larger then a 2-electrode system, with consistent heating within the entire zone. This performance is obtained across a broad range - from temperatures lower than a standard splicer can produce to heat suffi cient to fuse 1mm+ fibers. The result is incredible splicing versatility for specialty fibers, large diameter fi bers, high strength applications, and
high yield production processes.
The 3-Phase technology featured on the S184 provides an extremely stable, controllable, and repeatable heat zone. This can be used in a post-splice annealing
process that significantly increases the tensile strength of the fusion splice. The flame polish removes internal stresses and surface imperfections in the silica
created during the fusion process, increasing the tensile strength of the splice.
The improved stability, wide heat zone, and extended dynamic range of the 3-phase plasma field on the S184 provide superior results with Thermally Expanded Core (TEC) splicing processes. This method of core diffusion can be utilized pre or post splice to achieve significantly lower optical loss of fi bers with mismatched
mode field diameters (MFD).
The S184 is the world’s only splicer with 3-phase wide area arc technology, which allows for splicing of > 1mm fibers and unprecedented results for high strength and specialty fusion splicing. The “Ring of Fire” allows FITEL to take splicing to the next level and achieve results that have previously been impossible to achieve with
2-electrode systems.
