Next to the
regulations, another important boundary condition is the type of
market segments that the operator is willing to address.
Assuming a time
scale of 5 to 10 years, and after understanding the differences
between possible solutions for very-high-speed transport, we explore
the different markets that this technology may have in the near
future and how it fits into the existing frameworks.
A set of relevant
market segments exists. These can be categorized by:
-
· Inter-exchange market
-
·
Long-haul telephone companies
-
·
IP carriers (backbone)
-
· Enterprise market
-
· Big institutions
-
· SME
-
· SOHO
-
·
Regional communication providers
-
·
Traditional telephony service (local exchange)
-
· High speed pipes for private business oriented networks
-
· High-speed access networks to support Internet access, HDTV, interactive TV, and so on.
The analysis of
the sequel indicate the following market-technology mapping can take
place during the course of time, as the optical technology advances
to be mature and the bandwidth demand growth increases:
-
· Inter-exchange market
-
· SDH TDM
-
· SDH TDM with SDM (space division multiplexing)
-
· SDH TDM with WDM links
-
· All-optical networks (dynamic or static wavelength
routing networks)
-
· OTDM or MC-OTDM
-
· OCDMA or MC-OCDMA
-
· Enterprise market
-
· SDH TDM
-
· SDH TDM with SDM or WDM links
-
· All-optical networks with electrical switches (STM,ATM,
IP, etc)
-
· Regional communication providers
-
· SDH TDM with/without SDM/WDM links
-
· All-optical networks with electrical switches (STM, ATM,
IP switches)
-
· PONs (and their derivatives such as SuperPONs) for high
speed access to the home and SOHO
