Claim Text:
1. A method for constructing a space division-multiplexing (SDM) optical transmission system, the method comprising: setting the SDM optical transmission system to have a system bandwidth of 30 nm or less, including at least two wavelengths, the system bandwidth being the range of wavelengths that may be transmitted on the SDM optical transmission system; setting a number of spatial dimensions for the SDM optical transmission system depending on the system bandwidth, the number of spatial dimensions being two or more; providing an optical cable having the number of spatial dimensions; providing a spatial multiplexer configured to multiplex modulated optical signals on the number of spatial dimensions; providing a plurality of optical amplifiers, each of the optical amplifiers being configured for amplifying the plurality number of spatial dimensions; providing a spatial demultiplexer; and coupling the spatial multiplexer, the plurality of optical amplifiers and the spatial demultiplexer to the optical cable.
