Course Description:
Fiber optic systems are a key part of new communications services. Their success depends upon good design. This course provides a basic understanding of Fiber Optics, describing different Fiber types, the construction of point to point Fiber links, splicing, impairments and basic link design. It will examine the selection of wavelengths to use, and the use of multiple wavelengths in Course and Dense Wavelength Division Multiplexed systems. It will then provide an understanding of how these optical systems can be deployed using Remote Operation Add Drop Multiplexing Applications. Throughout the course students will undertake workshop exercises in order to be able to apply the knowledge learned.
Modern carrier networks must deliver reliable communications services that are secure and match the growing speed and capacity demanded by their customers. During the 20th Century we saw the growth in universal voice and this led to the development of SONET technologies based on Time Division Multiplexing technology. This has been used for early Internet services but these would benefit from packet based asynchronous designs and much higher data rate. 21st Century networks demand has been shaped by the inexorable growth in multimedia, social media and mobile services. Carrier Transport Networks must match the current demands with the right technologies delivered flexibly enough to adapt to the ever changing pattern of user demand. They must also be delivering service to the right place and at the right price.
This course is aimed at designers. It will be valuable to all those that want to be aware of the key sills of design, within the context of building new Transport Networks for tomorrows carrier services. These will raise the typical single wavelength 10 Gbits systems to 100 Gbits on Dense Wavelength Division systems carrying over 40 wavelengths per fiber.
While this is mainly concerned with long distance, high bandwidth core services, it is important to be aware of where and how the services will eventually be delivered. In the 1990s there was a massive grown in SONET and ATM technology within Transport Networks. However by the end of the 1990s it was realized that ATM was an expensive mistake as Switched Optical Ethernet offered a more powerful and cheaper solution. Also that SONET, optimized for voice services, was probably not the optimal solution either.
This course examines the demands which we are likely to place on our next generation of Transport Networks, identifies the options currently available for delivering reliability, security, aggregation flexibility, routing, switching and management. It then provides an approach to designing networks using standardized metrics to deliver services matching current and predicted future demand profiles. In-class exercises will uncover the key statistical techniques for estimating and prediction of future demand and confidence intervals. Using simple spread sheets and modelling students will learn from practical exercises how to design services to match their particular carrier network needs.
These techniques will then be applied to consider the design of carrier networks using Optical Transport technologies.
