FITEL S185EVROF

Precision Splicing For Novelty Fibers, Advanced R&D, & High-Stakes Production Environments

The FITEL S185EVROF is engineered for fibers most splicers aren’t equipped to handle. Hollow-core, multi-core, PM, LDF, high-index, and other novel configurations benefit from the S185EVROF’s three-electrode Ring of Fire arc-discharging system and industry-first Composite Image Technology.

Built for researchers, specialty fiber manufacturers, and production floors where splice quality determines performance, the S185EVROF delivers the visibility, heating control, and alignment accuracy required for next-gen fiber designs.

Engineered Accuracy for Demanding Fiber Types

Traditional single-electrode splicers struggle with hollow-core and multi-core fibers due to uneven heating and inconsistent end-face alignment. The S185EVROF solves this with a three-electrode Ring of Fire system designed to apply uniform thermal energy to delicate microstructures without collapse or distortion.

Key engineering upgrades include:

• STA²D Sequential Asymmetric Arc-Discharge, fine-tuned for hollow-core fibers and small-cladding geometries.
• Composite Image Technology, overlaying both end-view fiber images into a single frame for precise matching and reduced rotational error.
• Dual-Mirror End View System, enabling simultaneous visualization of both fiber ends.
• 0.1-degree rotational alignment, supporting demanding applications such as PMF, MCF, and sensor fibers.

If you need upstream support for fiber handling or cleaving prior to splicing, explore fiber preparation solutions.

Sized for the Lab, Built for the Line

Despite its advanced imaging and discharge systems, the S185EVROF maintains a compact footprint suitable for benchtop R&D labs and production environments.

Operational advantages:

• 104x, 278x, or 556x side-view magnification for detailed alignment.
• 64x end-view magnification for hollow-core inspection.
• Storage for 1,000 splice records including pre-splice and post-splice images.
• Up to 200 splice and 100 heater programs for custom fiber types and proprietary manufacturing recipes.
• Optional storage case available for hand-carry transport; a larger transport case is recommended for field or mobility use.

For teams integrating splicing into broader photonics workflows, glass processing systems provide complementary functionality.

Measured Results You Can Trust

Precision in novelty fibers requires trusted, measurable performance. The S185EVROF delivers repeatability across a wide range of fiber types.

Performance metrics:

• Typical SM splice loss: 0.014 dB
• Return loss: > 60 dB
• Typical PANDA extinction ratio: 40 dB 0.6° rotational offset
• Typical splice time: 15 s (SM)
• Typical heat time: 35 s (40 mm sleeve)
• Tension strength: 1.96 N

For cleaving prior to splicing, fiber cleaving tools pair seamlessly with the S185EVROF for optimal end-face quality.
