Similar to time-division multiplexing (TDM) or frequency-division multiplexing (FDM) which uses the medium of transmission as time and frequency respectively, space-division multiplexing (SDM) or spatial multiplexing uses the transmission medium as space. SDN uses the Cisco MSPPs to deliver SONET-based time-division multiplexing (TDM) services and metro Ethernet services to its customers. This broad-bandwidth device is not only a low-cost alternative to EDFAs for optical amplification, but is also a building block for next-generation switching and optical time-division multiplexing (OTDM) systems. |
