FIBER IN METAL TUBES
Thick Wall Alu Layered (ATT)
OPGW: Thriving in Harsh Environments
OPGW is often subject to harsh climate conditions such as wind, ice, and rain. The 3 mm outer aluminum casting of the ATT makes it suitable for deployments in the harshest environments. A stainless-steel tube protects the optical fibers from mechanical stress. The steel itself is protected by an aluminum layer that prevents galvanic corrosion within the cable, a common cause for OPGW failure.
The ATT can be produced with as many as 144 fibers at 250μm or 192 fibers at 200μm. The combination of its high optical fiber count, performance, and durability makes the cable one of the most financially sound solutions on the market. Our ability to offer custom solutions further enhance the potential of the ATT to thrive in any situation.
