- Bend Radius, No Load = 10x Cable Overall Diameter
- Bend Radius, Load = 15x Cable Overall Diameter
- Crush Test per Bellcore GR-409-CORE: 72 fiber NanoCore™ with
50/125 OM2 glass meets 3X the GR-409-CORE requirements. HCM has tested two samples of the 72 fiber Nanocore™ to 5X the GR-409-CORE requirement and it has passed.
Bend Radius for Cables that Contain Corning® ClearCurve® Glass are Typically 25% to 50% Smaller than Conventional Cable Designs. Call for More Technical Details.
