HYBRIFLEX® RRH Hybrid Cable Solution 6x12, 6AWG
Low-Inductance, 1-1/4”, Single-Mode Fiber With DLC Connectors

RFS’ HYBRIFLEX Remote Radio Head (RRH) hybrid feeder cabling solution combines optical fiber and DC power for RRHs in a single lightweight aluminum corrugated cable, making it the world’s most innovative solution for RRH deployments.

This low-inductance version of HYBRIFLEX allows mobile operators deploying an RRH architecture to deploy >400ft sites without the danger of power-cycling their RRHs due to voltage swings, which could occur in some specific instances. It combines bend-insensitive single-mode fiber (12 pairs of DLC connectors), 6 pairs of low-inductance DC wires and 9 pairs of 18AWG wires used to carry alarm signals. The package also includes a special RFS-designed DC insulating boot, used to properly protect and insulate the DC wires after stripping the jacket, avoiding possible short-circuits while wiring it to the distribution boxes. Standard RFS CELLFLEX® accessories can be used with HYBRIFLEX cable.


  • DC Wire Insulator (Patent pending) – Used at the DC wire connection in distribution boxes, prevents potential short circuits
  • Aluminum corrugated armor with outstanding bending characteristics – Minimizes installation time and enables mechanical protection and shielding
  • Same accessories as 1-1/4” coaxial cable – Saves installation costs and time
  • Outer conductor grounding – Eliminates typical grounding requirements and saves on installation costs
  • Lightweight solution and compact design – Decreases tower loading
  • Robust cabling – Eliminates need for expensive cable trays and ducts
  • Optical fiber and power cables housed in single corrugated cable – Saves CAPEX by standardizing RRH cable installation and reducing installation requirements
  • Outdoor, flame-retardant jacket – Ensures long-lasting cable protection
