dense wavelength division multiplexing

This course examines the general principles of fiber-optic transmission, offers an overview of SONET, and introduces participants to the operation of a wavelength division multiplexed system. This course explores the major components of a fiber system, the structure of the SONET frame, the features and benefits of SONET ring topologies, wavelength division multiplexing (WDM), WDM limitations, and the relationship between WDM, SONET, and other protocols. The course concludes with a discussion of dense wavelength division multiplexing (DWDM) architecture, systems, and products.

The key topics explored include:

• Bandwidth Drivers
• Lightwave Fundamentals
• Overview of SONET
• Wavelength Division Multiplexing
• DWDM Architecture and Products

This course is recommended for:

• Telecommunications professionals involved in the sale or implementation of optical networks
• Engineers involved in the development or design of optical networks
• IT staff building or managing optical networks
• Industry consultants providing support or services in optical network environments
• Managers of professionals who deal with optical network infrastructures at either the sale or implementation levels.
