08:00 - 09:30 Registration
09:30 - 10:30 Opening

Welcome address:
  • Mexico representative (TBC)*
  • Paolo Rosa, ITU/TSB
Keynote address:
  • Principal or Deputy Director of University (Mexico) (TBC)*
  Introduction to ITU-T and the objectives / structure of the Tutorial

Objectives: This session provides an overview of: the ITU and its Sectors and an introduction to ITU-T Study Group 15, to the Handbook and to the structure of the Tutorial.

Tutors:
  • Paolo Rosa, ITU/TSB: Introduction to ITU and its sectors;
  • Gerard Kuyt, Prysmian Group, The Netherlands: Introduction to ITU-T Study Group 15, 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.

Tutor:
  • Gerard Kuyt, Prysmian Group, The Netherlands
Week 1, Day 2, Tuesday, 20 September 2011
  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.

Tutor:
  • Gerard Kuyt, Prysmian Group, The Netherlands
Week 1, Day 3, Wednesday, 21 September 2011
  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.

Tutor:
  • Paolo Rosa, ITU/TSB
Week 1, Day 4, Thursday, 22 September 2011
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 joined 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.

Tutor:
  • Paolo Rosa, ITU/TSB
Week 1, Day 5, Friday, 23 September 2011
  Part I: 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.

Tutors:
  • Makoto Murakami, NTT, Japan
  • Gerard Kuyt, Prysmian Group, The Netherlands
Week 1, Day 6, Saturday, 24 September 2011
  “Crash” Course on “Optical Fibres”

Tutors:
  • Giancarlo De Marchis, TelCon srl, Italy
  • Makoto Murakami, NTT, Japan
  • Paolo Rosa, ITU/TSB
Week 2, Day 1, Monday, 26 September 2011
  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.

Tutor:
  • Makoto Murakami, NTT, Japan
Week 2, Day 2, Tuesday, 27 September 2011
  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.

Tutor:
  • Makoto Murakami, NTT, Japan
Week 2, Day 3, Wednesday, 28 September 2011
  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 also be provided.

Tutor:
  • Giancarlo De Marchis, TelCon srl, Italy
Week 2, Day 4, Thursday, 29 September 2011
  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.

Tutor:
  • Giancarlo De Marchis, TelCon srl, Italy
Week 2, Day 5, Friday, 30 September 2011
  Part I: 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.

Tutor:
  • Giancarlo De Marchis, TelCon srl, Italy
Part II: Quality Assurance, Conformity and Interoperability issues

Objectives: The ISO 9000 family of standards relate to quality management systems and are designed to help organizations ensure they meet the needs of customers. Implementing ISO 9001 it is guaranteed that, thanks to measures put in place by a manufacturer, the process to produce goods according to certain standards and meeting the customer's requirements is under control. An example applicable to submarine cables will be given. Conformity to standards requirements is a first step that can help in achieving interoperability of products from different manufacturers. This session will show the main aspects of Quality Assurance and the Conformity and Interoperability Programme that set up by ITU is applicable to Optical Fibers Systems.

Tutor:
  • Paolo Rosa, ITU/TSB
