Tough fibre cable with no metal armour can handle forklift weight

25 August, 2021

Belden has developed an optical fibre cable that avoids the need for metal armouring, and is up to 90% lighter and 70% smaller in diameter than metal armoured cable, and up to 50% smaller in diameter than non-armoured cable. The OptiTuff Mini Fiber cable is also said to be more flexible and easier to install than metal armoured cable and can survive a four-tonne forklift being driven over it.

This cable has an all-dielectric armouring that provides good durability and crush resistance, while delivering mechanical properties similar to metal armoured products. Because no grounding or conduit are needed, installers can save time and end-users can save money.

The cable has anti-kink properties and a small bend radius that make it flexible enough to handle tight, challenging turns in small spaces, raceways and cable trays. The cable can be stapled to a wall and, according to Belden, can survive a 14kg data centre tile being dropped on it, without any crushing, breaking, kinking or performance issues.

“This cable solution is remarkable,” says Belden’s fibre systems product manager, Kikie Kunplin. “Because it’s made of advanced, ruggedised thermoplastic material instead of a metal material, it’s a cost-effective, high-quality alternative to traditional armoured cable.”
