In today’s high-speed fiber optic networks, splice loss directly impacts signal quality, network uptime, and overall project cost. An advanced ARC Fusion Splicer with core-alignment technology has become the industry standard for backbone lines, FTTx deployments, MAN, and long-haul installations. At SeikoFire, our complete ARC Fusion Splicer series (from entry-level to flagship 6-motor models) delivers ultra-low splice loss (≤0.02dB typical), lightning-fast operation, and proven reliability across 60+ countries.


SeikoFire ARC Fusion Splicers are built around PAS (Profile Alignment System) and true core-to-core alignment technology. Using high-precision motors (4 to 6 motors depending on model), real-time arc calibration, and intelligent environmental compensation, every splice is automatically optimized for temperature, humidity, and altitude. This guarantees consistent performance whether you’re working in desert heat, high-altitude plateaus, or freezing winter conditions.


Key advantages of the SeikoFire ARC series:

  • Ultra-low loss: Typical 0.02dB (SM), 0.01dB (MM), 0.04dB (DS/NZDS)
  • Fastest cycle times: 6–9 seconds splicing + 15–20 seconds heating
  • Universal compatibility: SM (G.652/G.657), MM, DSF, NZDS, BIF, and large-diameter fibers
  • Industrial-grade durability: Dust-proof, shock-proof, and wind-resistant up to 15 m/s
  • Long electrode life: 4000–6000 discharges per pair
  • Smart features: Automatic fiber identification, arc position calibration, and one-click cleaning

From the compact S-16 handheld model perfect for FTTH last-mile work to the flagship S8 6-motor professional splicer used in national backbone projects, SeikoFire offers a solution for every budget and application. All models come with a 24-month warranty, free remote technical support, and lifetime electrode supply service.

Frequently Asked Questions (FAQs)

  1. What is the difference between cladding alignment and core alignment ARC splicers? Core-alignment splicers (like all SeikoFire models) physically align fiber cores for loss as low as 0.02dB, while cladding-alignment machines only align the outer glass, resulting in higher loss and less reliability on G.657 or bent-insensitive fibers.
  2. How long do electrodes last in SeikoFire ARC splicers? Depending on the model and usage conditions, electrodes last 4000–6000 discharges. We provide free replacement electrodes during the warranty period.
  3. Can these splicers handle drop cables and indoor tight-buffered fibers? Yes—all models include interchangeable fiber holders for 250μm, 900μm, 2–3mm drop cables, flat cables, and pigtails.
  4. Do SeikoFire splicers work with G.657A2 bend-insensitive fiber? Absolutely. Built-in G.657 programs and automatic fiber identification ensure optimal alignment and lowest possible loss on bend-insensitive fibers.
  5. What certifications do SeikoFire ARC fusion splicers carry? Every model is CE, ROHS, ISO9001, and SGS certified, and complies with Telcordia GR-326-CORE and IEC standards.
