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

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

Scenerio 2 : Earthquake on large FTTX deployed area
Main Telecom buildings are not damagedAC Mains is off Aftershocks are expectingSome buildings collapsed destroyed others undamagedTelecom infrastructure (Ducts, Pipes, Cables, Equipments …) partially destroyed in some areas but still big portion un damagedHigh amount of incoming voice and Data traffic towards
Disaster area Goverment agenciesRelief agenciesPress agencies………
DISASTER-EARTHQUAKE
RESULTS
Telecom infrastructure destroyed and out of service in some areasBig 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 ?
DISASTER-EARTHQUAKE
DISASTER-FLOODING
DISASTER-EARTHQUAKE
Fiber cables more sensible pressure than copper cables
Ring or mesh topoloji critical for FTTC cabinets
Power shortage is very criticalSpare FTTX equipment or boards and
batteriesFireMore network people to diagnose problems
and put equipments in service
