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. Passive optical networks allow an optical fibre to be shared by a number of customers for part of the connection from service provider to customer.
This course describes and compares the benefits, components and operation of the three main types of passive optical network (BPON, GPON and EPON) as used in various configurations including fibre to the home (FTTH) and fibre to the cabinet (FTTC).
Those studying the more technical aspects of this online course would benefit from a basic understanding of optical fibre principles, packet switching and time division multiplexing. It is suggested, therefore, that the e-learning courses SRB: ""Transmission fundamentals "" and SRC: ""Data communications principles"" are 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:
- explain how the limitations of copper-based access networks prevent many customers from benefiting from enhanced triple-play services.
- describe the basic structure of a passive optical network (PON), its cost and performance benefits and the role of its basic components.
- explain the techniques that allow customers to share the bandwidth offered by a single fibre.
- describe and compare the structures and benefits of various configurations of a PON including fibre to the home (FTTH), fibre to the node (FTTN) and fibre to the cabinet (FTTC).
- describe and compare the service features of various types of passive optical network (PON), and the equipment employed in FTTC and FTTH configurations.
- describe the role of the various customer premises equipment (CPE) and distribution methods in a home for a triple-play service (telephony, TV and Internet access).
- describe the protocols and techniques used to transport various types of traffic over Broadband PON (BPON) and Gigabit PON (GPON) systems.
- describe the benefits of a differentiated service and the techniques used for its provision in BPONs and GPONs.
- describe the implementation and role of dynamic bandwidth allocation in BPONs and GPONs.
- explain that the Ethernet PON (EPON) standards were developed to reduce the complexity of passive optical networks and reduce system costs.
- describe the protocols and techniques used to transport various types of traffic over an EPON.
- describe the role of the multipoint control protocol (MPCP) in an EPON.
- explain the limitations of the various methods used for a differentiated service in an EPON.
- describe the capabilities of the latest 10 Gbit/s generation of PON systems and explain how a faster bit rate system can co-exist with an older generation system on the same passive optical network.
