FN-WBA2840 Water-Blocking Aramid Yarn.
Water-swellable aramid strength-member yarn that combines dielectric reinforcement with dry water blocking for optical cables that want to reduce gels and tapes.

Water-swellable aramid strength-member yarn that combines dielectric reinforcement with dry water blocking for optical cables that want to reduce gels and tapes.
FIBRENEX® focuses on optical-cable reinforcement backed by controlled para-aramid manufacturing. This grade is intended for cable designs that require stable tensile support, consistent quality, and responsive engineering support.
- Combines dielectric reinforcement with dry water blocking
- Reduces dependence on gels and water-blocking tapes
- Built for optical cable strength members requiring flexibility and absorption
- Dielectric optical cable strength members
- Dry water-blocking cable designs
- Replacement for tapes and filling gels
