provide strength and second-line protection

Completely protected from water ingress

Maximum rated cable load up to 4496 lb

Rodent gnawing damage is a very common problem in the USA, and it might be both extremely costly and very dangerous. InAir ADSS FRP Defender is a multi tube fiberglass rods cable which is specifically designed to solve the rodent problem. This design has three lines of defense. The first line is an anti-rodent additive in the outer jacket to discourage chewing. The second one is an FRP rod to stop chewing if they do. Finally, an inner jacket ensures that the optical core is protected from water ingress. Its maximum rated design tension can be up to 4,496 lb. And, even though it is “InAir”, it can also be deployed underground as an all-dielectric direct bury solution.
