Introduction:

Optical networks are a key contributor to the rapid expansion of telecommunications services now underway. Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) have become the worldwide standard for the interface and multiplexing of user information to optical networks. SONET/SDH systems allow much greater network flexibility and management over existing optical systems. The study of SONET/SDH is therefore important for all involved with telecommunication and information technology. In this course, you will learn both the technology and applications of SONET/SDH. We will review the SONET/SDH system components as well as the end-to-end SONET/SDH network design process. We will also discuss the essentials of SONET/SDH synchronization, control, network management, and practical deployment issues. In short, this course will give you the knowledge and skills you need to understand and deploy this important technology.

Audience:

This course is designed to provide a general overview for strategic or technical managers, consultants, communications professionals, software engineers, system engineers, network professionals, marketing and sales professional, IT professionals, and others who plan on using, evaluating, designing or working with SONET/SDH, D/WDM and optical networks.

Prerequisites:

This is an introductory course with no prerequisites.

Customize it:

This 2-3-day SONET/SDH course will be customized to your needs and specifications. Enowireless will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Enowireless, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Objectives:

Learn how to: Understand the conceptual and theoretical underpinnings of this field Define the important SONET/SDH terms Identify applications of SONET/SDH Describe the detailed workings of SONET/SDH Name the key components of SONET/SDH systems and describe how they fit together Design a SONET/SDH system Describe the limitations of the SONET/SDH technology List the objectives and characteristics of the next generation SONET/SDH systems Describe the vision and structure of the Next Generation Network (NGN) project as it affects SONET/SDH
