HYBRIFLEX Standard LTE, Cabling Solution for 1 RRU

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 and the cost for an internal grounding wire.
The HYBRIFLEX cable is part of a site installation kit. It consists of an armored bundle of 2 DC cables, 1 F/O distribution cables and a rip cord to adjust the breakout part of the cable.


  • A corrugated armor with excellent bending characteristics minimizes installation time and enables mechanical protection and EMC shielding
  • Outer conductor grounding eliminates typical additional grounding requirement and saves on installation costs
  • Lightweight solution and compact design decreases tower loads
  • Robust cabling eliminates need for expensive cable trays and conduits
  • Installation of stripped fiber optic cable pairs directly to RRH reduces CAPEX and wind load by eliminating need for junction boxes
  • F/O and DC housed in single corrugated cable saves CAPEX by standardizing RRH cable installation and reducing installation equipments
