Question 2/6
Infrastructure and installation techniques for cables and equipment
(Continuation of Questions 4/6, 6/6 and part of Question 10/6)
1 Motivation
Increasing demand of higher capacity due to new products and services will require installation of outside plant elements in the access network using new techniques, suitable to the specific circumstances and devices involved in every particular situation.
The demand for more bandwidth will be satisfied by different technologies, from xDSL to fibre-to-the-premises that will need to be studied. Also, present installation techniques may evolve to include new cost effectively elements. Spread of optical fibre cables into the premises areas will be a key issue, especially in existing buildings without specific infrastructure for these new elements. Possible solutions include the installation of cables into existing facilities for other utilities (e.g., gas pipes, water conduits and sewers).
Finally, activities on installation of Marinized Terrestrial Cables (MTC), as portion of the terrestrial short and long distance network, need also to be considered.
2 Question
Study items to be considered include but are not limited to:
- What is the best method to install optical fibre cables and other network elements in buildings?
- How do telecommunication cables enter inside customer premises?
- Which is the state of the art installation techniques for new optical fibre cables?
- What is the possible evolution of installation techniques also using facilities for other utilities?
- What is the best strategy when constructing new infrastructure, taking into account integrity of installation, maintaining and growth issues?
- Are topics concerning marks and external protection of MTC, as well as intervention for reparations, sufficiently treated in existing ITU-T deliverables?
- This activity will be carried out in close relationship with other Questions of SG 6.
- An up-to-date status of work under this Question is contained in the SG 6 Work Program
(http://www.itu.int/itudoc/itu-t/com6/index.asp).
