Description
This CPRI cable is an armored type CPRI cable with a cable OD of 5.0mm. Its structure is as follows: There are 4 × 600um tight buffer fibers in it. A spiral steel tube covers those tight – buffer fibers to offer high protection. An aramid yarn covers the steel tube as a strength member. The cable’s jacket is made of LSZH material with anti – UV function.
