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
