METHODS OF LAYING FIBRE OPTICS

GENERAL INFORAMTION

 

As a matter of principle, the most cost effective method of laying fibre optics will be chosen:

Existing empty ducts

Shared use of existing ducts of local telecom and energy providersSuitable for point to point as an extension of Busi- ness Fibre Networks, backbone for FTTX

 

Utilization of existing infrastructure
Gullys and sewers

Suitable for all kind of networks

 

New construction (Public or civil works)
Suitable for all kind of networks

ADVANTAGES/ DISADVANTAGES

Existing empty ducts:

Legal issues, pricing, dependence, limited resources

 

Utilization of existing infrastructure:

Sewers: depending on approval of sewage system operator, cost efficient horizontal laying, method depending on sewer type (walkable or non-walk- able), position and its system (continuous connec- tions only in flow direction). Junctions are possible without construction work.

 

New construction (Public or civil works):

Permits, interference with traffic, annoyance of neighbours, subsequent connections require addi- tional excavation. Cost and effort vary from city to city and are dependent on surface and soil proper- ties.

SEWAGE GRID

 

In Central European cities, all inner-city buildings are connected to the sewage grid. The design of this grid is star-shaped. The focal point of the sewage is the waste water treat- ment plant, and for the rain water the nearest spillway (body of water).

Ranking of international Business Locations according to IT-Capacities. A functioning telecom infrastructure is the essential condition for economic development. A region-wide FTTH service network is an important part of the location advantage, just as a well developed road system or a reliable power supply. In order to avoid an unco-ordinated network development, the OECD recommends (in 2008) that private providers should take a leading part in the development of FTTH infrastructure, but the responsibility of the state should be to define devel- opment areas, providing appropriate incentives, and to promote reasonable com- petition. Avoidance of net duplication: uncoordinated investments in networks and unnecessary duplicate investments in infrastructure should be prevented.
