Question 7/6
Optical fibre cable construction and function
(Continuation of Question 8/6 and part of Question 10/6)
1 Motivation
Optical fibre cables have been widely used for recent 20 years based on rapid growth of telecommunication traffic. Therefore, ITU-T SG6 had created several recommendations on optical fibre cables for tunnel, directly buried, aerial and marinized terrestrial applications, respectively. Then a recommendation for access network applications, from the viewpoint of function, not environmental was also created. The demands on optical fibre cable will be growing still from now on. Therefore, these recommendations need to be modified continuously.
Next, optical fibre cables will spread into indoor areas. ITU-T SG15 decided to create a new question on indoor optical fibre specification. At the same time, another world standardization organization IEC SC86A is creating several optical fibre cable specifications for indoor applications very actively. This area will be one of important study areas in the future for optical transmission. Therefore, it should be better to discuss about what kind of dedication will be made by ITU-T for this kind of application.
MTCs (Marinized Terrestrial Cable as defined in ITU-T Recommendation G.972) are a portion of the terrestrial short and long distance network and have to be also considered.
2 Question
Study items to be considered include but are not limited to:
- What are the future and the state of the art technologies on optical fibre cables?
- What kind of problems occurs on optical fibre cables which are installed in the field?
- What are the desirable optical fibre cable constructions and functions for indoor application?
- Are existing ITU-T Recommendations and /or handbook a suitable description on construction and protection of
MTCs?
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).
3 Tasks
- To modify existing recommendations for optical fibre cables. 2007
- To create optical fibre cable recommendation for a new application if required. 2007
- To create draft new recommendation on construction and performance of MTCs 2007
- Revision of existing handbook on MTC. 2007
- To discuss desirable optical fibre cable constructions and functions for indoor
application.
- To avoid duplication of work, exchange information on overlapped items with other standardization bodies.
