2. 2 Why use Satellite, RF & Microwave Fiber?

3. EMCORE Corporation Proprietary 3 What is Linear (or RF) Fiberoptics ? DIGITAL RF in CATV Satellite Wireless Radar RF Out CATV Satellite Wireless Radar Analog to Digital to Analog RF Out RF in Tx RF modulated light in the fiber Optical Power, average Rx

4. EMCORE Corporation Proprietary 4 Reason #1: Distance - we call it “antenna remoting” Why RF Fiberoptics ?  Serve remote locations  Consolidate & simplify operations  Back-up redundant facilities  Possible because of fiber’s low RF loss

5. 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

6. 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

7. EMCORE Corporation Proprietary 7 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

8. EMCORE Corporation Proprietary 8 Cost Considerations  Fiber, Cable & Equipment  Construction & Real Estate  Installation  Maintenance Cost Considerations  Fiber, Cable & Equipment  Construction & Real Estate  Installation  Maintenance Reason #5 Lower COST - “the bottom line” Why RF Fiberoptics ?
