Core Innovation Highlights

What Makes AI-20 Different?

The AI-20 isn't just another fusion splicer – it's a complete fiber optic toolkit integrated into a single, portable unit. Unlike traditional solutions requiring separate equipment for splicing, cleaving, power measurement, and fiber diagnostics, the AI-20 combines four essential functions into one intelligent machine.

Full-Link Integration Design means you arrive at a job site with everything needed:

• Precision fusion splicing (6 seconds)
• Electric one-step cleaving (patented delayed-return technology)
• Optical Power Measurement – OPM (-50 to +30dBm)
• Visual Fault Locator – VFL (up to 10km range)
• Built-in 9-in-1 fiber stripper
• Real-time luminous flux assisted alignment

Advanced Features That Set AI-20 Apart

Feature #1: Full-Link Integration Design

What It Means

All four essential fiber optic tools integrated into a single, compact unit. No need to carry separate equipment or manage multiple devices.

What's Included

🔹 Fusion splicer
🔹 Electric fiber cleaver
🔹 Optical Power Meter (OPM)
🔹 Visual Fault Locator (VFL)
🔹 9-in-1 Signal Fire fiber stripper

Benefits

✅ Reduced equipment weight (4.5 kg total vs. 8–12 kg for separate tools)
✅ Faster job setup and completion
✅ Lower total cost of ownership
✅ Easier transportation to remote sites
✅ Simplified inventory management

Typical Scenario:
A fiber installation contractor previously carried: fusion splicer (2.5 kg), separate OPM meter (1.2 kg), separate VFL (0.8 kg), electric cleaver (1.5 kg) = 6 kg of separate equipment. With AI-20, one compact 4.5 kg case does it all.

Feature #2: Patented High-Precision Delay Return Electric One-Step Fiber Cleaver

The Technology

Signal Fire's proprietary delayed-return mechanism prevents the traditional problem of mechanical cleavers scratching fiber end faces during return movement. This innovation solved a problem that has plagued fiber technicians for decades.

How It Works

1. Fiber placed and secured in cleaver
2. Blade advances and makes clean cut
3. Intelligent delay (0.2–2.0 seconds, user-configurable)
4. Blade returns only after delay period
5. No scratching of fiber end face

Automatic Blade Management

• Cleaver blades automatically track usage
• After 1,000+ cuts, system alerts operator
• Blades self-identify when dull
• Two consecutive cutting failures trigger blade change alert

Benefits

✅ Eliminates fiber end-face scratching
✅ Reduces splicing loss and rework
✅ Extends blade life
✅ LED auxiliary lighting (app-controlled brightness)
✅ Consistent cutting performance in all conditions

Field Result: Technicians report 30–40% reduction in splicing retries when using AI-20 compared to mechanical cleavers.

Feature #3: Real-Time Luminous Flux Assisted Alignment

What This Technology Does

Continuously monitors optical signals during fiber alignment to identify the lowest-loss alignment point in real-time, then automatically positions fibers for optimal splicing.

How It Improves Your Work

• Reduces Trial & Error: No guessing about fiber positioning
• Minimizes Loss: Finds the true best alignment, not just "good enough"
• Increases Confidence: Visual confirmation of optimal alignment on 5-inch display
• Speeds Productivity: Less rework means more splices per day

Real-World Example:
Two-fiber optical signal analysis shows alignment loss of 1310nm at -15.37dBm. System continuously adjusts fiber position, analyzing loss in real-time. When optimal alignment achieved (loss improves to -14.93dBm), technician executes splice with confidence.

Requirements

Works best with stable optical signal link from front fiber source (typical field conditions).

Feature #4: Integrated OPM & VFL Functions

Eliminate Separate Equipment

Previously, technicians needed to carry:

• Separate optical power meter ($800–1200)
• Separate visual fault locator ($300–500)

Now both are built in.

OPM Capabilities (Optical Power Meter)

• 10 switchable wavelengths for comprehensive testing
• Measures from -50 to +30 dBm
• Perfect for pre- and post-splice verification
• Confirms signal strength across entire network

VFL Capabilities (Visual Fault Locator)

• Traces fiber lines up to 10 km
• Identifies breakpoints and damage
• Detects light leakage from connector issues
• Essential for troubleshooting and installation verification

Applications

✓ Test fiber links before splicing
✓ Verify signal strength post-splice
✓ Locate fiber breakpoints
✓ Identify light leakage problems
✓ Confirm installation quality

Feature #5: Compact & Highly Portable Design

Weight & Dimensions

• Total Package: 4.50 kg (9.9 lbs) – lighter than most laptops

• Robust Design: Tested in extreme field environments

Why This Matters

Field technicians don't have time for slow equipment. The AI-20's industrial-grade processor ensures responsive operation throughout the workday, even after hundreds of splicing cycles.

Feature #8: Complete 9-in-1 Signal Fire Fiber Stripper

Included Tools

What This Eliminates

No need to purchase separate stripping tools – this complete set handles every common cable type:

• 5G FTTH deployment cables
• Traditional FTTH drop cables
• Multi-layer armored cables
• Bare fiber with protective sheaths

Feature #9: Extended Battery Life for Full-Day Field Operations

Capacity Details

• Battery: 7800mAh high-capacity lithium
• Splicing Capacity: 240+ cores per full charge
• Typical Field Use: 8–10 hours continuous operation
• Charge Time: ≤3.5 hours (dual charging channel)

Dual Charging Strategy

Channel 1: Charge machine while operating
Channel 2: Charge spare battery separately

Result: Zero downtime for full-day and multi-day projects

Winter Preheating Function

Automatic 6-second preheat cycle activates upon successful splice completion, ensuring optimal performance in cold environments without operator intervention.

Real-World Scenario

Field crew starts work at 8 AM with full charge. By 3 PM, after splicing 180 cores, battery still has 25% capacity remaining for evening wrap-up work. One-hour charge cycle at lunch means full capacity for afternoon operations.
