(Continuation of Question 6/6)

Background and justification

There is an increase in the types of optical fibre cable network architectures that are being introduced into access networks. Due to the increase in traffic, cables with higher fibre counts (typically 100 fibres) are being installed in the access network. As a result many transmission systems are transported within the same optical cable. In order to achieve a high reliability in these networks the maintenance of the outside plant is important. There is therefore a requirement to study maintenance systems which are highly reliable and fast to respond.

Study items

• Optical fibre outside plant maintenance support, monitoring, and testing system.
• Optical fibre maintenance criteria for access networks with point-to-multipoint and ring architecture.
• Optical fibre maintenance methods for access networks.

Relationships

• ITU-T SG15
