Optical fibre provides far higher data transfer rates than copper wires. So telecoms providers are installing optical fibre in their access networks to offer customers high speed access to the Internet and other services such as streaming TV and movies.
This course describes the use of optical fibre in the access network, the role of the active and passive components of optical access networks and the practical aspects of installing and testing broadband access systems including FTTH, FTTC and FTTB.
To gain maximum benefit from this course, you will need an understanding of the basic principles of optical fibre transmission. It is recommended that the course OLA: ""Optical fibre principles"" is studied before attempting this course.
This e-learning course has a comprehensive range of interactive training facilities to provide a total learning experience. Technical words and acronyms have links to an online glossary giving an instant explanation. Interactive simulations explain concepts and systems operation. Onscreen question sessions at the end of each module test understanding and provide further guidance and instruction. Revision links provide quick access to subjects previously discussed and relevant to the module being studied. Once studied as a structured, assessed course, the content can be browsed for revision or reference.
By the end of this course you will be able to:
- describe the various configurations and role of the components of point to point and point to multipoint links in an optical access network and explain what limits the maximum length of these links.
- describe and compare the capabilities and applications of point to point optical links, and FTTH, FTTB and FTTC broadband connections.
- describe how the structure of, and the materials used in, optical cables depends on the environment in which they are to be installed, giving examples of typical structures of internal and external cables.
- describe the techniques and equipment used to prepare and install optical cables with reference to installation in ducts, overhead suspension, and air blowing in microducts.
- describe the function and typical internal layout of various types of cable termination enclosure.
- describe the topology of an access network providing point to point links to business customers and describe the role of the components of such a network including the various types of optical enclosure.
- describe the role of the passive and active components of a passive optical network delivering FTTH and FTTB services with reference to both single and multiple dwelling unit installations.
- describe the role of the components of a network delivering an FTTC service with reference to the role of the ONU / DSLAM and VDSL splitter in the street cabinet.
- describe the use of optical loss test sets and dual port power meters to check that optical links and passive optical networks meet their power budget requirements.
- describe the principles, characteristics and use of an Optical Time Domain Reflectometer (OTDR) with particular reference to testing a passive optical network.
