Description

Submarine optical cables are also underwater fibre cable, but the laying environment conditions are more stringent and more demanding than general underwater optical cables. The service life of submarine optical cable systems and their components is required to be more than 25 years.

So underwater fibre optic cable must adopt a steel wire armour, which is also known as SWA. And the sheath must be considered comprehensively according to the hydrogeological conditions of the river.

Application

Underwater, Climbing, Direct burial

Features

• Steel wire armouring (SWA) improves tensile and impact resistance
• Double PE sheath, excellent moisture resistance
• Steel wire used as the central strength member
• Good hydrolysis resistance and high strength
• Water-blocking tape and materials
• Good mechanical properties and temperature characteristics
• Loose tube filled with special tube filling compound ensure critical protection for fibre
• Crush resistance and flexibility
