    3. 3 Overview Wave Division Mutiplexing (WDM) multiplexes multiple optical carrier signals on a single optical fiber by using different wavelengths (colors) of laser light to carry different signals. Bit rate and protocol independent

    4. 4 Overview

    5. 5 Overview Two main types of WDM: Coarse Wavelength Division Multiplexing (CWDM) Dense Wavelength Division Multiplexing (DWDM)

    6. 6 Overview Fiber Characteristics

    7. 7 Overview WDM Components

    8. 8 Overview Sub-Lambda Multiplexing Multiplexing a single low rate data connection onto a wavelength is very inefficient. For example, if a FastEthernet connection is transported on a WDM wavelength, only 4% of the bandwidth is used. This assumes the wavelength is capable of transporting 2.5 Gbps. To better utilize bandwidth many vendors support sub-lambda multiplexing. The cards that support this are often referred to as DataMux or Muxponder cards. Muxponder cards have multiple ports (FE, GE, etc.). These cards multiplex the data flows and transports them onto a wavelength. Some vendor use SONET framing to multiplex the data Others use proprietary protocols
