HBF078-U2S4-630-LI
HYBRIFLEX® Hybrid Feeder Cabling Solution 2x4, 7/8”, 2 pairs 6AWG, Low-Inductance Coaxial Power Wire, 4 pairs Single-Mode Fiber, DLC Connectors, 630 ft

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 may eliminate the need for junction boxes as well as works in conjuction with 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
  • Same accessories as 7/8" 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
  • UL-Listed, flame-retardant jacket, UV protected assembles - Allows both indoor and outdoor applications
  • Maximum robustnessFully armored cable includes riser trunk and top outdoor breakout

NOTES

Nominal length equals length of trunk not including top and bottom breakouts; breakout lengths add additionally to the total assembly length tip to tip.

Includes 5 pairs of wires used to carry alarm signals.

The package also includes a kit of special RFS-designed DC insulating boots, 1 per coaxial power wire, used to properly protect and insulate the DC wires after stripping the jacket, avoiding possible short-circuits while wiring it to the distribution boxes.
