Product Advantage
-
1
Ultra-Low Optical Loss & Superior Signal Uniformity
Industry-Leading Insertion Loss: 1x4 (≤7.2 dB @1310nm) / 1x8 (≤10.5 dB @1310nm) — 0.3-0.5 dB lower than mainstream competitors, reducing signal attenuation and extending transmission distance by up to 15% in FTTH/5G backhaul networks.
Minimal PDL (≤0.15 dB): Ensures stable signal transmission across all polarization states, avoiding performance fluctuations in high-speed optical systems.
Tight Uniformity (≤0.4 dB): Uniform power distribution among output ports eliminates "weak signal" issues in multi-user scenarios, improving network reliability. -
2
Direct-Input Molded LGX Design: Cost & Space Efficiency
Adapter-Free Direct Input: Integrates input port directly with the PLC chip, removing redundant adapters to reduce insertion loss (0.2 dB saved) and component cost. Compatible with standard LGX packages, enabling plug-and-play integration into 19-inch ODFs without additional modifications.
Molded Reinforced Package: Metal-reinforced plastic housing (exclusive mold) offers 30% higher mechanical strength than conventional plastic packages, while reducing weight by 20% — ideal for space-constrained data centers and outdoor cabinets. -
3
Extreme Environmental Adaptability & Durability
Wide Temperature Range (-40°C to +85°C): Complies with harsh operating conditions in polar regions, deserts, and high-altitude areas (exceeds Telecordia GR-1209-CORE’s standard range of -20°C to +70°C).
Rugged Mechanical Performance: Withstands 120N static load, 100g shock, and 1000 cycles of dynamic bending (radius ≥50mm) — no optical performance degradation (ΔIL ≤0.1 dB), ensuring 24/7 stability in industrial or outdoor deployments.
5-Year Warranty: Backed by strict 100% factory inspection (optical/mechanical/visual) and long-term reliability testing (1000h damp heat, 96h salt spray), reducing B2B customers’ maintenance costs and downtime risks. -
4
Global Standard Compliance & Universal Compatibility
Dual-Certified (IEC 61753-021 Category U / Telecordia GR-1209-CORE Level 1): Meets international technical norms, ensuring seamless compatibility with global optical network infrastructure (e.g., European FTTH, Middle Eastern 5G projects, Latin American data centers).
G.652.D Fibre & Multi-Connector Support: Compatible with standard single-mode fibres and optional SC/LC/FC connectors (IEC 61754), adapting to diverse customer network architectures without customization delays. -
5
Cost-Optimized Total Ownership (TCO) for B2B Partners
Reduced Installation Time: Direct-input design and LGX standard footprint cut on-site integration time by 40% compared to non-standard splitters.
Low Maintenance: High-quality PLC chip (from top-tier suppliers) and precision molding process reduce failure rate to <0.05% annually, lowering long-term replacement and labor costs for telecom operators, system integrators, and data center owners.
Customizable Fibre Length: 0.5m-2.0m flexible options eliminate waste from excess cable, optimizing material costs for specific project requirements. -
6
Exclusive Mold Design & Brand Differentiation
NOARK-exclusive molded LGX package ensures structural uniqueness, avoiding patent disputes and enhancing product competitiveness for B2B customers in bidding scenarios.
Compact, lightweight design (20% lighter than metal packages) reduces shipping costs by up to 15% for bulk orders — a key advantage for global distributors and project-based clients.
Each advantage is validated by third-party laboratory tests (per IEC 61753-021 & Telecordia GR-1209-CORE) and field-proven in 500+ global projects (FTTH, 5G, data centers), delivering tangible value for NOARK’s B2B partners in terms of performance, cost, and market competitiveness.
