  • 7.5mm Minimum Bend Radius: G657A2 supports bends as tight as 7.5mm radius without significant signal degradation — ideal for MDU in-building wiring, tight corners, and high-density patching fields.
  • G652D Backward Compatible: G657A1/A2 fibers are fully compatible with standard G652D fiber — seamless splicing and connectorization with existing network infrastructure. Mode field diameter matched at 1310nm.
  • FTTH MDU Optimized: Specifically engineered for multi-dwelling unit in-building FTTH deployments where cables must navigate tight corners, small conduits, and crowded cable trays without performance loss.

Applications
FTTH In-Building MDU

Multi-floor risers with tight 90-degree turns in small conduits. G657A2 handles bends that standard G652D cannot.

High-Density Data Center

Tight cable management in 1U and 2U patch panels. Reduced bend loss ensures consistent link budgets in crowded racks.

Fiber to the Room (FTTR)

Invisible fiber deployment along baseboards, door frames, and through wall corners without performance penalty.

Factory Direct — ITU-T G.657 Compliant

All bend insensitive fibers are 100% OTDR tested with macro-bend verification at 1550nm. Available in G657A1 or G657A2 with SC, LC, FC, ST connectors. Custom cable diameter, jacket material, and length. Contact us for OEM/ODM and bulk pricing.
