� Future 3-play services supporting multi-channel HDTV and 3D TV require huge bandwidth
� Furthermore there are upcoming services that are huge bandwidth generating sources:
• multi-player on-line gaming
• cloud computing
• Storage
• remote application hosting
• social networking and collaboration applications (i.e. videoconferencing, tele-presense)
• home management services (i.e. video surveillance)
� Cisco estimated that the average number of services that generate significant traffic increased from 11 to 18 over the past year
� ...and in addition to that the average number of users per household increases as well

� UDWDM uses an extremely narrow wavelength grid to pack a high amount of low to medium speed channels in a small wavelength band. The high number of multiplexed channels sums up to a high aggregate capacity on the metro link, for instance 100 channels with 1 Gbps each (100 Gbps).
� To enable the high channel density needed to accommodate the channel number in a moderate wavelength interval, a narrow filtering method is required to perform the channel selection in the receivers. In addition, to achieve a power budget which covers passive transmission over metro distances and high splitting passive optical networks, high receiver sensitivity is a pivotal element. Coherent receivers with single-channel electrical (noise) bandwidth only, combined with modulation schemes which employ constellations with high symbol distances are hence preferable.

� Depending on the households density a different trench size should be used at different parts of the OSP network (i.e. feeder, distribution, drop).
� The cost of each trench includes:• Trenching cost• Backfilling cost• Blacktopping cost• Duct installation cost
� Trenching on pavements is considered to be significantly higher than trenching on roads or countryside
� No RoW costs considered
