Introduction:
 
The revolution in optical transmission technologies begin at the beginning of this decade has allowed operators to drastically increase their transmission capabilities at a fraction of the costs of legacy technologies. This introductory course is intended to provide the fundamentals of dense wave division multiplexing, and will also touch on coarse wave division multiplexing, for network planners, engineers and designers alike.
 
Audience:
 
Telecommunications transport engineers, network planners, systems engineers, capacity managers involved in the day to day operation and management of large telephony systems.
 
Prerequisites:
 
None
 
Customize it:
 
This 2-3-day DWDM course will be customized to your needs and specifications. Eno.com 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 ame on the title slide. This minimizes their effort and time investment. At Eno.com, 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:
 
To provide a solid foundation in optical transmission technologies including DWDM, Coarse WDM and the T-carrier system.
