Description
4F 7.0mm CPRI Armored cable is an armored type CPRI cable with a cable OD of 7.0mm for FTTA projects. The fiber channels of this cable are 4x 900um tight buffer cables. A spiral steel tube covers those tight buffer cables to offer high protection. An aramid yarn covers the steel tube as a strength member. CPRI cables establish a reliable, highspeed connection between remote radio heads and base stations. These cables link the remote radio head to the base station’s CPRI interface, enabling the seamless transfer of data at exceptional speeds.
Features:
- High anti-tensility; High anti-pressure
- High bent Resistance; Anti-bite from rodent animals
- Small OD stainless steel protection tube
- Don’t worry about damage in project
- The flexible metal tube steel tape functions as protection as well as reinforcing the crush.USE as normal soft cable.
- Resistance and mechanical performance.
- The jacket possesses good ultra violet radiation resistant property.
