Reason #1: Distance - we call it “antenna remoting”
Why RF Fiberoptics ?
CATV Headend
Up to 80 km of standardsinglemode fiber (no amps)
FOTX Serve remote locations
Consolidate & simplify operations
Back-up redundant facilities
Possible because of fiber’s low RF loss
EMCORE Corporation Proprietary 5
Why RF Fiberoptics ?
Reason #2 Bandwidth
0.01 to 18 GHz
Also optimized bands at IF, L, C, X & Ku
DWDM provides another > 16X capacity
EMCORE Corporation Proprietary 6
Why RF Fiberoptics ?
Reason #3 EMI Immunity & Security
EMI, EMP, & ground loop “hum” elimination
Simple cable routing because no cable cross-talk, even next to high power lines
Lightning protection
Military TEMPEST protection because fiber can not be tapped

Why RF Fiberoptics ?
Reason #4 Lightweight & Compact 1/10 weight of coax, 1/25 of
waveguide
Important on ships, aircraft & towers
Easy installation – flexible & thin
Armored Kevlar versions also available
Lends itself to redundancy & cable routing diversity
