Sub-rate Multiplexing

Sub-rate Multiplexing is the process of placing several data streams onto a single wavelength, in an effort to further increase the number of data streams in a WDM system. There are several mechanisms of sub-rate multiplexing:

TDM - Time Domain Multiplexing (SONET and many proprietary versions)
FDM - Frequency Domain Multiplexing (e.g., QAM)
Statistical Multiplexing (Ethernet or other Layer-2)

This example shows how multiple channels of ESCON can be converted with the Fiber Driver-LD ESCON Solution into a single wavelength before wave division multiplexing, allowing up to 64 ESCON channels on a 16 wavelength CWDM system, or hundreds of ESCON channels using DWDM. The LD product also offers 2-Port Gigabit Ethernet Multiplexing modules.
