 ITU-T Tutorial on Optical Fibre Cables and Systems
 Kigali, Rwanda, 6 – 17 September 2010 Contact: 

Draft Programme

Week 1, Day 1, Monday, 6 September 2010
08:00 – 09:30 Registration
09:30 – 10:30 Opening

Welcome address:
  • Host country representative
  • David Mellor, Chairman, UKTA
  • Reinhard Scholl, Deputy to the Director of the Telecommunication Standardization Bureau, (ITU/TSB)
Keynote address:
  • Dr Ignace Gatare, Minister in the Office of The President in Charge of Information and Communications Technologies, Rwanda (TBC)*
Monday Introduction on the ITU-T and on the objectives / structure of the Tutorial

Objectives: It is an overview of the ITU, its Sectors and an introduction to ITU-T SG15, to the Handbook and to the structure of the Tutorial
Optical fibres characteristics (Note. Test methods are outside the scope of the Handbook. Moreover the description of the test methods (G.650.1, G.650.2, G.650.3) requires an advance knowledge of mathematics)

Objectives: This session will provide the participants with the description of the dimensional, optical, mechanical and transmission characteristics of the optical fibres. The ITU-T types of optical fibres will be described. This will give the elements to choose the type of fibre that best meets the needs of an optical plant based on the services and systems requirements.
Week 1, Day 2, Tuesday, 7 September 2010
Tuesday General characteristics of optical cables

Objectives: The optical cables must protect fibres from mechanical, chemical and human activities. In particular the structure of optical cables is to be designed to protect fibres to withstand the environment where the cable has to be installed: aerial, ducts, underground, shallow water, submarine.
Week 1, Day 3, Wednesday, 8 September 2010
Wednesday Optical cables installation [Note. Test methods are outside the scope of the Handbook.]

Objectives: The installation is linked to the session before. Specific techniques, such as underground ducts, trenchless techniques, mini-trench, micro-trench, aerial, tunnels, bridges, along railways, in sewer ducts, shallow water and submarine, will be analysed.
Week 1, Day 4, Thursday, 9 September 2010
Thursday Optical splices, connectors and passive nodes [Note. Test methods are outside the scope of the Handbook.]

Objectives: Fibres and cables are produced according to factory lengths that need to be jointed in order to realize the optical links. This session will provide a description of the best techniques for the interconnection of the optical fibres and in particular the optical fibre splices, optical connectors, optical distribution frames, fibre closures, fibre organizers, etc. All these elements are necessary to guarantee an optimized transmission of the optical signal along the fibre.
Week 1, Day 5, Friday, 10 September 2010
Friday Optical active and passive components / subsystems

Objectives: There are various passive and active components in an optical/plant: optical transmitters, optical receivers, optical amplifiers, chromatic dispersion compensators, regenerators, transponders, etc. This session will provide the description of these components, will outline how they are used in the optical systems / plants and will indicate the criteria for their choice.
Week 2, Day 1, Monday, 13 September 2010
Monday General characteristics of optical systems and their specification

Objectives: This part of the tutorial is of fundamental importance. Knowing the characteristics of the optical systems will give the participants the skills they need to make the right choice of equipment which are specified on the basis of applications, optical fibres, number of channels, wavelength of operation, future needs for new services, etc.
Week 2, Day 2, Tuesday, 14 September 2010
Tuesday Optical systems design

Objectives: In this part there is the description of the various approaches which can be followed for the design of the optical systems. Moreover the impact of the various impairments on the length of the links and on their capacity are evaluated. The main elements necessary for the design of an optical system will be given.
Week 2, Day 3, Wednesday, 15 September 2010
Wednesday Optical systems applications

Objectives: Ability to design an optical plant for a specific application will depend on the knowledge of the subjects dealt with in all the previous sessions. An optical system design based on a given Quality of Service and on a given life-time is a “must” for any engineer in order to choose the best optical system for each application in their network and for the needs of his country. Some information on submarine systems will be also provided
Week 2, Day 4, Thursday, 16 September 2010
Thursday B- and G-PONs - xDSL, Passive Optical Networks, Broadband PON, Gigabit-PON, Digital Subscriber Lines, Wireless broadband.

Objectives: This part will complete the training showing, from a general point of view, the user-side (last-mile) of a plant/system. This is the part closer to the end-users and to the needs of the service providers. The various techniques that are presently used will be described together with their advantages and drawbacks both for wired and wireless networks.
Week 2, Day 5, Friday, 17 September 2010
Friday Operation & Maintenance, safety and environmental aspects

Objectives: Operation and maintenance are elements that the engineers have to learn in order to take actions to limit the effects of systems failures or low performance.
