Question 9/6
Joint closures, termination and distribution frames, outdoor enclosures and
passive components
(Continuation of Question 7/6)
1 Motivation
The evolution of the (fixed network) telecommunication market, led mainly by the increasing demand of higher capacity and integrated services, creates new requirements to the hardware used to construct the access network.
Depending on the status of existing infrastructure as well as practical and economical factors, the demand for more bandwidth will be achieved by different technologies such as:
- xDSL on copper pairs (central office or remote based);
- coax and hybrid-fiber- copper;
- fibre to-the-home (both passive and active).
This will generate new needs and requirements at the access network nodes, comprising:
- storage and powering of remote electronics;
- reliability and reconfigurability of optical access nodes;
- environmental protection of passive optical components and optical connectivity.
2 Question
Study items to be considered include but are not limited to:
- Functional requirements and test methods for outdoor and indoor enclosures fit to accommodate passive as well as active components. Special focus shall be given to optical nodes for the FTTH networks.
- Environmental protection of Passive Optical components and Modules in Outside Plant, including: splitters/couplers and other branching devices; wave division multiplexers and filters; attenuators etc.
- Functional requirements for optical connectivity in the access network, including all types of splices and optical connectors
- Environmental protection of active and passive components and equipment for copper networks. This may include requirements related to the thermal management of nodes
This latter activity will be carried out in close relationship with SG 15, defining only the mechanical and environmental characteristics of the products, as per the mandate 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).
