THE BOUNDARY OF LIVING SPACE
FIBER REACHES THE BOUNDARY OF THE BUILDING, SUCH AS THE BASEMENT IN A MULTI-DWELLING UNIT, WITH THE FINAL CONNECTION TO THE INDIVIDUAL LIVING SPACE BY CAT-6 (COPPER CABLE)
Depending on the type of area, income level, topology and conditions of competition, FTTH, FTTB or FTTC solutions are implemented.
FTTH Selected greenfield areas, industrialized areas
FTTB Existing customers, business areas, high income residences, etc.
FTTC Locations where rapid transformation is required and use of local cable is feasible

7. DISASTER-EARTHQUAKE
Scenerio 1 : Earthquake on large FTTX deployed area
Assumptions
Main Telecom buildings are not damaged
AC Mains is off
Aftershocks are expecting
Collapsed or Destroyed;
Buildings
Telecom İnfrastructure (Ducts, Pipes, Cables, Equipments …)
High amount of incoming voice and Data traffic towards
Disaster area
Goverment agencies
Relief agencies
Press agencies
………

8. DISASTER-EARTHQUAKE
RESULTS
Telecom infrastructure destroyed and out of service
There is no way to quickly recover infrastructure and provide service other than Mobile capabilities.

9. EFFECT OF EARTQUAKE

10. EFFECT OF EARTQUAKE

11. DISASTER-EARTHQUAKE
Scenerio 2 : Earthquake on large FTTX deployed area
Main Telecom buildings are not damaged
AC Mains is off
Aftershocks are expecting
Some buildings collapsed destroyed others undamaged
Telecom infrastructure (Ducts, Pipes, Cables, Equipments …) partially destroyed in some areas but still big portion un damaged
High amount of incoming voice and Data traffic towards
Disaster area
Goverment agencies
Relief agencies
Press agencies
………

12. DISASTER-EARTHQUAKE
RESULTS
Telecom infrastructure destroyed and out of service in some areas
Big Part of Network in good condition and works
But still there is risk to loose all services
Since Mains off, Fuel is running out, Battery back up times are exceeding
How we can maintain services ?

13. DISASTER-EARTHQUAKE

14. DISASTER-FLOODING

15. Fiber cables more sensible pressure than copper cables
DISASTER-EARTHQUAKE
Fiber cables more sensible pressure than copper cables
Ring or mesh topoloji critical for FTTC cabinets
Power shortage is very critical
Spare FTTX equipment or boards and batteries
Fire
More network people to diagnose problems and put equipments in service
