A-3 Optical Fiber Fusion Splicer for Fiber-Optic FPV Spools

A portable arc fusion splicer for joining optical fibre in the field — for repairing or extending the fibre spools used on fibre-optic FPV drones, as well as FTTx and telecom maintenance. It runs on a rechargeable Li-ion battery and handles single-mode, multi-mode and dispersion-shifted fibre.

Key features

• Low-loss splices: typical loss of about 0.02 dB on single-mode and 0.01 dB on multi-mode fibre, with return loss above 60 dB.
• Dual cameras and colour LCD: high magnification for accurate fibre alignment, in automatic or manual mode.
• Fast cycle: splices in about 5–7 seconds, and the built-in heater shrinks 10–60mm protection sleeves.
• Battery operation: about 200–250 splice-and-heat cycles per charge.
• Records and updates: stores thousands of splice results, exported over USB, which also handles firmware updates.
• Rugged build: shock-, dust- and moisture-resistant, for use from -10°C to +50°C.

• Cladding diameter: 80–150 µm
• Cleave length: 5–16mm
• Splice loss (typical): SM 0.02 dB, MM 0.01 dB, DS/NZDS 0.04 dB
• Return loss: over 60 dB
• Splice time: 5–7 s
• Heating time: 15–26 s
• Splicing programmes: up to 40
• Electrode life: 4,000–5,000 arcs
• Tension test: approx. 2 N
• Operating temperature: -10°C to +50°C

Most fibre-optic FPV spools use bend-insensitive single-mode fibre (G.657), which this splicer supports. Each joint also needs a precision cleaver, a fibre stripper and a protection sleeve, so keep those on hand for field repairs.
