THE BOUNDARY OF LIVING SPACE
• 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
FTTC
Existing customers, business areas, high income residences, etc.
•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)
Locations where rapid transformation is required and use of local cable is feasible

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
………
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.
EFFECT OF EARTQUAKE
EFFECT OF EARTQUAKE
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
………
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 ?
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 critical
Spare FTTX equipment or boards and
batteries
Fire
More network people to diagnose problems
and put equipments in service
