HBF058-08U1SS2-xxF1 Series
HYBRIFLEX® RRH Hybrid Jumper 1 pair, 8AWG, 5/8", Single-Mode, 2 Single Strand Fibers with LC 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.
         It was developed to reduce installation complexity and costs at Cellular sites. HYBRIFLEX allows mobile operators deploying an RRH architecture to standardize the RRH installation process and eliminate the need for and cost of cable grounding.
HYBRIFLEX combines optical fiber (multi-mode or single-mode) and power in a single corrugated cable. It eliminates the need for junction boxes and can connect multiple RRHs with a single feeder. Standard RFS CELLFLEX® accessories can be used with HYBRIFLEX cable.


  • Single Strand Fiber
  • 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
  • UL-Listed Components, flame-retardant jacket, UV protected assembles→Allows both indoor and outdoor applications
