RFS Unveils HYBRIFLEX, the World’s First Lightweight Aluminum Hybrid Feeder Cabling Solution for Remote Radio Heads

COLOMBES, France , April 22, 2010 /PRNewswire/ — With HYBRIFLEX, its
revolutionary new RRH hybrid feeder cabling solution, Radio Frequency Systems
(RFS), the global wireless and broadcast infrastructure specialist, becomes
the first company to combine optical fiber and DC power for Remote Radio
Heads (RRHs) in a single lightweight aluminum corrugated cable. RFS' patented
solution enables the cabling expenditure reductions, ease-of-installation and
operational efficiency mobile operators need to evolve their networks while
limiting their power consumption and carbon footprint at cellular sites.

Upgrading technology, reducing operating expenditures (OPEX) and
decreasing CO2 emissions at cellular sites are constant challenges for
operators around the globe. As part of their efforts, many operators are
deploying a distributed base station architecture where RRHs are installed
next to the antenna on the tower or rooftop rather than deploying old-style
macro base stations. Installing RRHs close to antennas reduces costs by
cutting power consumption – typically in half – but means RF transmission,
power and grounding cables must all be brought to the RRH on the tower or

Recognizing operators' challenges, RFS developed HYBRIFLEX, which allows
operators to connect up to three sectors with a single composite optical
fiber and power cable with the grounding function incorporated directly in
the cable.

“RFS' innovative single-cable architecture allows operators to reduce the
number of RRH cables required from nine to one,” explains Marc Kaeumle, Vice
President, RF Transmission and Distribution at RFS. “Along with decreasing
the load on the tower or rooftop, HYBRIFLEX dramatically simplifies and cuts
the cost of installation while enabling significant savings. For example,
installation of stripped fiber optic cable pairs directly to the RRH
eliminates the need for expensive junction boxes and limits wind load. In
addition, by enabling simple, flexible and cost-effective deployment of RRHs
close to antennas, HYBRIFLEX helps operators reduce power consumption at
their cellular sites – an important step toward achieving their CO2 reduction
objectives,” concludes Kaeumle.

HYBRIFLEX's unique design and structure offer additional important

    - To simplify inventory management of cable accessories,
      HYBRIFLEX is designed according to standard RF feeder diameter. This
      means commonly available RFS CELLFLEX LCF 1/2-inch and LCF 7/8-inch
      feeder accessories can be used in all HYBRIFLEX installations.

    - For maximum flexibility, HYBRIFLEX can be connectorized
      on-site. Alternatively, pre-connectorized solutions and services are
      available to help standardize the RRH cabling process.

    - To ensure an extremely lightweight cable, the armor is
      aluminum. Aluminum also offers the fragile fiber optic cables inside
      more protection than polyethylene tubes and at a much lower cost than
      cable trays.

Incorporating the grounding function, which is critical to RRHs, also
eliminates the need for and cost of cable grounding.
