HB158-21U6S24-xxM Series
HYBRIFLEX® Hybrid Feeder Cabling Solution 6x24, 4AWG, 1-5/8”, Single-Mode Fiber, DLC to ODC, with 6AWG DC breakout top

Rev : G | Rev date : 16 Feb 2021

PRODUCT DESCRIPTION

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. 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. Both pre-connectorized and on-site options are available.

FEATURES / BENEFITS

  • Aluminum corrugated armor with outstanding bending characteristics – Minimizes installation time and enables mechanical protection and shielding
  • Armored fiber optic breakout – Preserves the integrity of the fiber and provides mechanical/environmental protection
  • Same accessories as 1-5/8" coaxial cable
  • Outer conductor grounding – Utilizes same grounding methods as coaxial cable
  • Lightweight solution and compact design – Decreases tower loading
  • Robust cabling – Eliminates need for expensive cable trays and ducts
  • Installation of tight bundled fiber optic cable pairs directly to the RRH – Reduces CAPEX and wind load by eliminating need for interconnection
  • Optical fiber and power cables housed in single corrugated cable – Saves CAPEX by standardizing RRH cable installation and reducing installation requirements
  • Outdoor, black PE jacket – Ensures long-lasting cable protection
  • Shielded DC wire – Jacketed and braided cable on top breakout provides grounding and EMI protection
  • Maximum robustness – Fully armored cable includes riser trunk and top outdoor breakout
