Fusion Splicer vs Mechanical Splicing: Which is Better?
What is fusion splicing?
Fusion splicing joins two fibers by melting them together using an electric arc.
What is mechanical splicing?
Mechanical splicing aligns fibers using a sleeve without melting.

✅ FAQ
Q1: Is the COMWAY A33 suitable for FTTH installation?
A: Absolutely. The A33 is specifically designed for FTTH deployment with fast 5-second
splice time, lightweight 1.8kg body, and 240+ battery cycles for all-day field work.
Q2: What is PAS alignment and how does it differ from core alignment?
A: PAS (Profile Alignment System) aligns fibers by their outer cladding profile rather
than the core directly. It's fast, reliable, and ideal for standard FTTH fiber types
(G.652D), offering a great balance of speed and accuracy at a lower cost than 6-motor
core alignment splicers.
Q3: How does the COMWAY A33 compare to Fujikura 90S or Sumitomo splicers?
A: The A33 delivers comparable FTTH splicing performance to premium Japanese splicers
at roughly 1/3 the price, making it the top choice for cost-conscious contractors and
telecom companies.
Q4: Can the COMWAY A33 work at high altitudes or in cold weather?
A: Yes. The A33 operates reliably from -10°C to +50°C and at altitudes up to 5,000m,
making it suitable for mountain terrain and extreme climate deployments.
Q5: What warranty does the COMWAY A33 include?
A: The A33 comes with a 1-year standard manufacturer warranty.
