Power Connect cable 3,3 mm² for connection of one RRU

Rev : A | Rev date : 13 Mar 2019

RFS' HYBRIFLEX ™ cabling solution for Remote Radio Unit (RRU) combines optical fiber and DC power in a single lightweight aluminum corrugated cable, making it the world’s most innovative solution for RRU deployments. It was developed to reduce installation complexity and cost at Cellular sites.

HYBRIFLEX™ cabling solutions allows mobile operators deploying RRU architecture to standardized installation process and eliminates the need for and the cost of cable grounding.

The HYBRIFLEX™ Power Connect cable PW-S-03S4-J consists of four unshielded pair

DC wires protected by a corrugated Aluminum armor.


  • UV resistant jacket
  • Comply with IEC 60228
  • Flexible
