  1. FSO Installation Free Space OpticsThe Practical Aspect

  2. The Path to a successful IR link 2 • Site survey • Choosing the right product • Design for safe (worst case) margins • Perform a clean “by the book” installation • Test end-to-end link connectivity

  3. Preparation

  4. Performing the Site Survey 4 1. Choose a mounting location 2. Confirm line of sight (Site A to Site B) 3. Note where fiber and power should terminate 4. Determine link range using GPS or other methods 5. Photograph the site 6. Go to Site B and repeat steps 1-5 7. Complete the site survey check list (Site Survey Form)

  5. Choose A Mounting Location 5

  6. Line of sight 6 • Clear line-of-Sight • Atmospheric disturbances • dust clouds • smoke • large vehicle traffic (fumes) • Physical obstacles • Moving objects (cranes etc.) • Trees • Birds Nesting

  7. Line of sight With chimneys 7

  8. Line of sight With chimneys 8 Link Location active Chumminess

  9. Site Survey 9 • Scintillation Sources • Air conditioning units • Long, hot, rooftops • Smokey chimneys • Heavy traffic exhaust fumes • Metal Roofing

  10. Long, hot, rooftops 10 Long hot roof can cause scintillations NetLight Unit

  11. Long, hot, rooftops 11 Long metal roof can cause heavy scintillations during summer time And can affect the traffic. The NetLight should be higher at list 15feet above the roof

  12. Long, hot, rooftops 12 Better location to mount the NetLight

  13. Long, hot, rooftops 13 Are you crossing this roof?

  14. Air conditioning units 14 Point B (Bad location) Point A (Good location)

  15. Air conditioning units 15 • Vibrations • Stable mount • Wind • Compressors • Elevators • Traffic • Building Sway • Wooden buildings • Earthquake buildings

  16. Site Survey Windows and East-West Links 16 • Windows • 4% light reflection from each surface • 15% loss from a double pane window • Tinted windows increase attenuation • NetLight should be placed at an angle greater than 1 and never more than 45 away from perpendicular to thewindow.Green, gray, brownand mirror window are not recommended because of very high attenuation • East-West links • Errors if 0.5 sun disk overlaps the NetLight • Only for a few days a year • Only for a few minutes each day Note: When transmitting trough window it important to notify the customer that From time to time the link can be blocked by the window cleaner elevator

  17. Transmit Trough Window Drawing 17

  18. Transmit Trough Window Picture 18 Marking for the window cleaners Taking off part of the window coating

  19. Photograph The Site 19 • Photograph the location • Spot alternative mounting locations (if necessary) • Photograph the line-of-sight ( From the NL final height) • Photograph the overall roof top • Photograph the under line terrain

  20. Bad Line Of Sight Example 20

  21. 21 Installation

  22. Rooftop Mounting 22 • Four types of Mounts • Wall pedestal mounts • Floor pedestal mounts • Extended wall mounts • Pole clamps mounts

  23. Wall Pedestal Mount 23 Wall Pedestal Mount. Used when the link needs to be elevated above the top of the wall. M054C - 10 inches from base plate M053C - 22 inches from base plate M022C – 34 inches from base plate • .

  24. Floor Pedestal Mount 24 Reinforced Floor Pedestal Mount. Similar to the Standard Floor Pedestal. M015C - 47 inches (concrete) M059C - 47 inches (Indoor) M058C - 34 inches (Indoor) M050C – 34 inches (concrete) M055C - 22 inches (concrete) M057C - 22 inches (Indoor)

  25. Extended Wall Mount 25 Extended Wall Mount. Used when a standard wall pedestal mount is insufficient to clear obstacles or for applications requiring an extension from the wall for better access to the transceiver. M064C - 12 inches (metal for PCL) M051C - 22 inches (concrete) M056C - 34 inches (concrete) M062C - 22 inches (metal) M063C - 34 inches (metal)
