Cable Characteristics:

High strength aramid yarn strength member ensures high tensile strength and long term stability in transmission
Small outer diameter, lightweight, flame-retardant, easy to strip, low attenuation, physically soft
Direct splicing between tight buffer cables and need no tie-in box or pigtail
Suitable for installation, operation, and convenient for maintenance

Double Sheath Applications:

As building to building connecting cable
As indoor soft cable along the wall, ceiling, between layers and in conduits
As pigtails, movable connectors and patch cords for communication equipment
