GDTA Access Network Optical Hybrid Cable

Product Description:

Colored optical fibers are placed in a loose tube made of  high-modulus, water-resistant material, filled with  moisture-blocking gel. The center of the cable is a metal  strength member. The loose tube and the required specification  of insulated copper conductors are twisted around the center  strength member to form a compact circular core. The  interstices of the cable core are filled with water-blocking  material. After longitudinal wrapping with coated aluminum  tape, a polyethylene outer sheath is extruded to form the cable.


Product Feature:

◆ Optical-electrical integration solves the problem of equipment  power supply and signal transmission.  

◆ Reduces procurement costs and saves construction  expenses. 

◆ Precise control of excess length of optical fibers and cable  core structure inside the loose tube ensures that the cable  meets the required tensile performance and temperature  characteristics of product standards.


Environmental Characteristics:

Transportation/Storage/Operating Temperature:  -40°C to +70°C


Delivery Length:

Recommended Length: 2000m; other lengths can be provided according to customer requirements.
