Hybrid Optical and Electrical Stranded Loose Tube Cable (GDTA)

Single-mode/multimode fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. In the center of cable is a metallic strength member. The tubes and copper wires (of required specifications) are stranded around the central strength member to form a cable core. The core is filled with cable filling compound and armored with laminated aluminum tape. Then, a PE sheath is extruded.
Features

• Accurate process control ensuring good mechanical and temperature performances
• Optical and electrical hybrid design, solving the problem of power supply and signal transmission and providing the centralized monitoring and maintenance of power for equipment
• Improving manageability of power and reducing coordination and maintenance of power supply
• Reducing procurement costs and saving construction costs 
• Mainly used to connect BBU and RRU in DC remote power supply system for distributed base station 
• Applicable to duct and aerial installations
