BendCom® Bending Insensitive single-mode fiber G.657.A2
Product Introduction
BendCom® G.657.A2 bend-insensitive single-mode fibers are available in both 200μm and 242μm diameters. Featuring an advanced high-performance resin composite coating, the 200μm variant achieves exceptional bending loss performance with a minimum bend radius as small as 5mm. This optimized mechanical design makes these fibers particularly suitable for FTTx deployments in confined metro environments and last-mile network installations where space constraints demand reliable small-radius routing.
Product Performance
Industry-leading bend performance
Engineered with G.657.A2 compliance, the fibers demonstrate superior bend loss resistance (<0.03dB @ 1550nm @ 10mm radius), maintaining signal integrity even in tight routing configurations.
Space-optimized form factor
The 200μm fiber variant delivers a 34.5% reduction in cross-sectional area compared to standard 242μm designs, enabling high-density cabling solutions for duct congestion mitigation and micro-cable applications.
Application Scenarios
- High-density fiber management in multi-dwelling unit (MDU) riser systems;
- Micro-cable deployment for duct congestion mitigation in metro tunnel environments;
- FTTH drop cable installations with tight-radius corner routing;
- OSP cabling in historical buildings with architectural preservation requirements;
- Data center inter-rack fiber routing in space-constrained cold aisles;
- Industrial automation networks with dynamic bending requirements.
