Softing FiberFox MINI4S+
Compact active-alignment fusion splicing for professional fibre installation and maintenance.
Compact fully automatic active-alignment fusion splicer for general fibre installation, FTTH, LAN and field work.
What is Softing FiberFox MINI4S+ and when should you use it?
Softing FiberFox MINI4S+ is a professional fusion splicer used to permanently join optical fibres with low splice loss. Splicer selection should be based on alignment method, fibre type, field environment, production volume and the level of splice performance required. Practical preparation, cleaving, arc calibration and splice protection remain critical regardless of model.

Training Available
Fibre Optics Training UK can provide practical training around Softing FiberFox MINI4S+, including fibre preparation, cleaving, splicer setup, arc calibration, alignment, splice protection and splice-loss quality control. Training is designed to help engineers understand not only which buttons to press, but what the result means, when the test method is appropriate and when a different verification, qualification or certification tool is required.
Manufacturer-neutral training using leading industry equipment
Fibre Optics Training UK uses equipment from multiple leading manufacturers, including Fluke Networks, Softing, EXFO, VIAVI, Fujikura and INNO. Our training is manufacturer-neutral and standards-led: learners are taught the underlying test method, correct setup, result interpretation and practical workflow so they can work confidently across different platforms rather than being trained around one brand.

FAQs
What is Softing FiberFox MINI4S+ used for?
Softing FiberFox MINI4S+ is a professional fusion splicer used to permanently join optical fibres with low splice loss. Splicer selection should be based on alignment method, fibre type, field environment, production volume and the level of splice performance required. Practical preparation, cleaving, arc calibration and splice protection remain critical regardless of model.
What is the difference between verification, qualification and certification?
Verification checks basic wiring and continuity. Qualification proves whether a link can support a target network application or data rate. Certification measures the parameters required by cabling standards and produces a formal PASS/FAIL result.
How do I know whether this is the right tester for my job?
Choose the instrument based on the evidence the project requires: basic wiremap or continuity, live-network troubleshooting, Ethernet performance qualification, standards-based copper certification, Tier 1 optical loss testing or Tier 2 OTDR analysis.
How does Softing compare with Fluke Networks, TREND Networks and NetAlly?
The brands overlap in several categories but organise their portfolios differently. The right choice depends on whether you need verification, qualification, certification, fibre loss testing, OTDR analysis, PoE diagnostics or live-network troubleshooting. Compare required test standards, speeds, media, reporting workflow and support rather than brand name alone.
Can Fibre Optics Training UK help compare test equipment before purchase?
Yes. We can help identify the test method and equipment category that matches the installation standard, client requirement, network speed and reporting obligation.
Is practical training available?
Yes. Practical training is available on relevant test methods and equipment workflows, including setup, test selection, result interpretation, fault finding and reporting.
Do I need a certifier if I already have a network tester?
Not always. A network tester may be ideal for commissioning and troubleshooting, but if the contract requires standards-based cable certification you need an appropriate certifier capable of producing the required PASS/FAIL evidence.
What should I compare besides the purchase price?
Compare test scope, supported standards and speeds, copper/fibre capability, PoE support, accessories, calibration requirements, reporting software, workflow, warranty/support and the training needed to use the instrument correctly.
