COMWAY A3 Fusion Splicer — Lightweight FTTH Field Splicer with PAS Alignment
The COMWAY A3 is a compact, professional-grade fiber optic fusion splicer built for FTTH installers and field technicians who need reliable performance in a lightweight, portable package. Weighing just 1.5kg, the A3 delivers a 6-second splice time with a high-precision PAS (Profile Alignment System), making it one of the most efficient entry-to-mid-range splicers available for single-fiber field work.
With 240 splice-and-heat cycles per charge, dust and rain resistance, and fast boot technology, the COMWAY A3 is engineered to keep up with demanding deployment schedules — whether you're running FTTH drops, building out FTTx networks, or maintaining existing fiber infrastructure.

Frequently Asked Questions
What is the difference between the COMWAY A3 and COMWAY C6S?
The COMWAY A3 uses a PAS (Profile Alignment System) and is lighter at 1.5kg, making it ideal for high-volume FTTH drop installations where portability matters. The COMWAY C6S uses a 6-motor core-to-core alignment system for higher precision and lower splice loss, suited for backbone and more demanding splicing applications. The A3 offers 240 cycles per charge vs. the C6S's 350 cycles.
What fiber types does the COMWAY A3 support?
The A3 supports SM (G.652), MM (G.651), DS (G.653), NZ/NZDS (G.655), and Bend-Insensitive (G.657) fiber types — covering all standard fiber used in FTTH, FTTx, and telecom networks.
How fast does the COMWAY A3 splice?
The A3 completes a splice in 6 seconds and heat shrink protection in 15 seconds — one of the fastest heating cycles in its class.
What is the battery life of the COMWAY A3?
The A3 supports 240 complete splice-and-heat cycles per charge, sufficient for a full day of FTTH field installation work.
Is the COMWAY A3 suitable for outdoor use?
Yes. The A3 is rated for dust, rain, wind (up to 15m/s), and shock resistance. It operates from -10°C to +50°C at altitudes up to 5,000m — ideal for outdoor aerial and underground fiber work.
Does the COMWAY A3 come with a warranty?
Yes, the COMWAY A3 includes a 12-month warranty. It ships worldwide within 5 business days of payment. Returns must be arranged in advance — please contact us before returning any item.
How does the COMWAY A3 compare to Fujikura fusion splicers?
The COMWAY A3 offers comparable PAS alignment performance to entry-level Fujikura models (such as the Fujikura 90S) at a significantly lower price point, making it a cost-effective choice for contractors and ISPs deploying large-scale FTTH networks.
