Why use Satellite, RF & Microwave Fiber?

1. EMCORE Corporation Proprietary

2. Why use Satellite, RF & Microwave Fiber? EMCORE Corporation Proprietary

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

4. FO TX Up to 80 km of standard singlemode fiber (no amps) CATV Headend Why RF Fiberoptics ? • Serve remote locations • Consolidate & simplify operations • Back-up redundant facilities • Possible because of fiber’s low RF loss Reason #1: Distance - we call it “antenna remoting” 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 EMCORE Corporation Proprietary

7. Install This... Pressurized Copper Elliptical Waveguide Pressurized Copper Coax Flexible Fiberoptic Cable. Up to 96 fibers in one 1/2 inch cable Or This... Equipment Room Operations Center 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 EMCORE Corporation Proprietary

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