(Continuation of Question 4/6 and 6/6)
The demand for broadband access services has increased throughout the world
in recent years. Fibre-to-the-home (FTTH) services constitute the most promising
approach to providing these services because of their large transmission
capacity and cost-effectiveness. The number of FTTH subscribers is increasing
rapidly, and a large number of optical fibre cables are being installed daily to
meet demand. Therefore, the smooth construction, operation, and cost effective
technologies for the maintenance of this network plant has increased
considerably in importance.
During the installation and maintenance of optical fibre communication
networks, field engineers must first correctly identify a specific fibre from a
bundle of fibres to avoid the incorrect cutting and/or connection of an optical
fibre at a worksite. Therefore, it is important to investigate functional
requirements for optical fibre identification, identification procedures and
methods that can be employed without any deterioration in optical communication
signals in access networks.
Trunk line communication traffic is also increasing rapidly owing to the
increase in FTTH services. An optical fibre line testing system is essential for
reducing maintenance costs and improving service reliability in optical fibre
networks. Some technologies that are used in trunk lines (e.g. WDM system and
EDAF) require additional functions and procedures for optical fibre line testing
systems. This Question will study the system requirements that will allow us to
achieve the reliable maintenance of the optical cables for trunk lines.
In addition, new telecommunication infrastructure will be deployed using a
lot of optical fibres, cables, enclosures, cabinets and passive optical
components. Concrete solutions for planning, collecting and managing these items
are becoming essential from the point of view of the optical facility
operations. It is also important to protect them from disasters in order to
provide sustainable telecommunication services.
Questions to be considered in the study include, but are not limited to:
- What are functional requirements for optical fibre identification without
any deterioration in optical communication signals in access networks?
- What procedures and methods can be employed for optical fibre identification
without interrupting optical services during maintenance work on optical access
- What are functional requirements for an optical fibre line testing system for
optical trunk lines?
- What kinds of reliable technologies can apply to preserve and protect outside
- Study new solutions for GPS (Global Positioning System) referenced network
- Study new solutions to monitor critical network elements by means of sensor
- Do the existing ITU-T Recommendations and handbooks provide an up-to-date
coverage of the techniques required to maintain an optical fibre cable
Tasks include but are not limited to:
- Optical fibre identification for the maintenance of optical access networks
- Solutions to monitor critical network elements by means of sensor networks
- Use of GPS (Global Positioning System) to create referenced network maps

optical fibre cables networks for trunk (2012)
- To create the state of the art technologies using optical fibre cables and/or
ubiquitous sensor networks (USN) for outside plant facility health monitoring
- Revision to existing Recommendations, if necessary.
