1 Type of study
Task-oriented Question that should result in a set of new Recommendations.
2 Motivation
Recent fibre optical transmission technology allows extending
fibre networks to the curb, the building or the home.
Fibre networks can be brought closer to users' premises than
hybrid fibre coaxial networks.
Fibre technology can provide the higher capacity in the
forward and return channel, which is required for the provision
of typical cable television services, including interactive
ones.
3 Questions
- Which mechanisms can be used
to transport multichannel analogue and/or digital television
signals over fibre networks, in view of the high loss of
optical splitters used for PON (passive optical networks)?
- Which mechanisms can be used
to ensure the low composite distortion and high CNR
(carrier-to-noise ratio) that are required for FDM (frequency
division multiplex) transport of mixed analogue and digital
television signals over fibre networks?
4 Expected results and anticipated target dates
The study will result in a first new Recommendation by the end of 2001.
5 Relationships
Liaison with SG 15 is needed in the study of this Question.
