  2. Next Topic

  3. Vertex Splice Enclosure

  4. MCB Network Hardware • 1 Gbit/s Transceivers • Typical Equipment used to determine RFI • Will be installed in shielded enclosure in the Antennas

  5. Preliminary RFI Testing of the MCB Hardware • Chamber test with 2 of 5 Switches • Large # of strong discrete signals near 1GHz • -66 dBW EIRP @1 GHz • This is 89 dB stronger than –155 dBW limit • The RFI Cabinet • Provided 25dB of shielding from 1-4 GHz

  6. Fiber Cable Lab

  7. Areas of Investigation • Power supply filtering • Grounding of Enclosures • Grounding of metal parts of Switches • Move the MCB cabinet to Ped Room • Cable Wrap Location
