High-Density Indoor Fiber Optic Cable for FTTH Deployments
Telhua's 4mm White Indoor Subscriber Cable G657A2 delivers exceptional performance in space-constrained environments. Engineered with G657A2 bend-insensitive fiber, this cable maintains signal integrity even when routed around tight corners or through crowded pathways. The compact 4mm diameter and flexible design enable efficient installation in high-density applications like multi-dwelling units, office buildings, and data centers.
Addressing Critical B2B Installation Challenges
Network installers face significant challenges when deploying fiber in indoor environments. Traditional cables often require excessive space, complicate pathway management, and increase installation time. Our 4mm cable directly addresses these pain points:
- Space Optimization: 40% smaller diameter than standard indoor cables maximizes pathway capacity
- Reliability Assurance: G657A2 fiber maintains <1dB/km attenuation at 1550nm with 10mm bend radius
- Installation Efficiency: Flexible construction and smooth jacket reduce pulling force by 35%
- Aesthetic Integration: Clean white jacket blends seamlessly with modern interior designs

Telhua Engineer's Tip: Bend Performance Optimization
When deploying in high-density racks or tight corners, maintain the 10mm installation bend radius. For permanent installations, our G657A2 fiber supports 7.5mm long-term bend radius without performance degradation. Pre-plan routing paths to avoid consecutive tight bends within 1-meter intervals, as cumulative micro-bending effects can increase attenuation by 0.05-0.1dB. Use radius guides in corner transitions to maintain optimal signal integrity throughout the cable lifespan.
Standards Compliance & Quality Assurance
This indoor subscriber cable meets rigorous international standards including IEC 60794-2-20 for optical fiber cables, TIA/EIA-598-D for color coding and identification, and RoHS Directive 2011/65/EU for hazardous substance restrictions. Each production batch undergoes comprehensive testing for attenuation, mechanical performance, and environmental durability, ensuring consistent quality for mission-critical network deployments.
