RFS HYBRIFLEX

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 RRH architecture to

standardize the RRH installation process. HYBRIFLEX® combines optical fiber (multi-mode or single-

mode) and DC power wire in a single corrugated cable and can connect multiple RRHs with a single

feeder.

HYBRIFLEX

cables are manufactured, pre-terminated, with various types of termination and are cut

to specific lengths. The aluminium outer conductor facilitates easy transportation (because it is light-

weight) and handling. Moreover this cable is easier to bend than other optic / power solutions using

a steel outer conductor.

Page 21: Fixation/Mounting Of The Cable
The crush resistance of aluminium is lower than copper, which should be considered when tightening the clamps (especially if these clamps have not been approved by RFS). A number of different clamps may be used, and we recommend using the SNAP-series products. The SNAP hanger is suitable for all fixing situations as well as being the safest (most failure proof) clamp, offering a large number of exceptional advantages.
