FITEL S185EVROF Hollow-Core Fusion Splicer

Overview

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.

Traditional two electrode splicers can struggle with hollow-core and multi-core fibers due to uneven heating and inconsistent angular 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.

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

Key Capabilities

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
104x, 278x, or 556x side-view magnification for detailed alignment, and 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
Full fiber-holder ecosystem from 160 to 1300 µm, USB and Wi-Fi connectivity

Fibers should be applied to ITU-T standard. In case of other fibers, depending on the type of fiber, the optimization of splice program may be needed or the splice result may not be satisfied.
Due to the high temperature of ROF, it may not be possible depending on the diameter, thickness and material of the coating.
These are references. Depending on the environment and condition, the number vary.
