• Small diameter, low weight reduces retrofit impact
• Hermetically sealed stainless steel tubes provide mechanical and thermal protection for fibers
• Thick-walled aluminum pipe provides crush resistance and boosts fault current rating
• Outer wire strands selected to optimize mechanical and electrical properties
• Lower wind and ice loads put less load on structures
• Fiber grouped in bundles of 12 for ease of splicing

Typical design for Double Layer of OPGW:

• For use by electric utilities on transmission lines in lieu of traditional shield wire
• For retrofit applications where existing shield wire needs to be replaced with OPGW
• For new transmission lines instead of traditional shield wire
• Voice, video, data transmission
• SCADA networks
• Dark fiber leasing
