ITU-T Study Group 15 List of Questions Under Study (Study Period 2005-2008) |

ITU-T SG 15 Question 10/15 |
|
Optical fibres and cables for the access network to and in buildings and homes (Continuation of Question 20/15)
- Motivation
The growing demand for broadband services (multimedia, high-speed internet, HDTV, etc.)
in buildings and homes requires the introduction of high-capacity transmission
media into the local network. Optical fibre would be an important option for
any broadband media mix created for this purpose.
The responsibility under this Question includes new Recommendations and/or
Supplements for fibre and cable implementation strategies.
The following major Recommendations, in force at the time of approval of this
Question, fall under its responsibility: As this Question was created in
October 2003, there are not yet any Recommendations in force.
- Question
- What is needed to cost-effectively provide optical access networks
to and in buildings and homes?
- What media reliability issues arise in the environment of the local network?
- What fibre category and/or Recommendations are appropriate?
- If new fibre types are needed, what are their requirements?
- What should be included when considering the compatibility and/or
connectability of any new fibre types with existing G.65x fibres?
- What new test methods are needed?
Study items to be considered include, but are not limited to:
- Evaluation of various media, such as plastic optical fibres
- Overall optimization of the end segment of the local network
- Strategies for mixed transmission media, such as hybrid fibre/coax
- Reliability (lifetime and failure rate); long-term aging in cooperation with ITU-T SG 6
- Tasks
Tasks include, but are not limited to:
- Develop the requirements for the overall optimization of the
end segment of the local network, taking into account the
trade-off of optical fibres/cables, components, and subsystems,
and utilizing existing Recommendations and standards
- Develop the requirements for new Recommendations or parameter
tables within existing Recommendations for possible new fibre types
- Develop a Supplement on the implementation strategies for
broadband transmission media to buildings and homes
Note: An up-to-date status of work under this Question is contained in the
SG 15 Work Programme.
