There is also the potential to use more bespoke technologies, like high density coarse wavelength division multiplexing (HDCWDM)--which is a bi-directional variant of CWDM--allowing double the capacity without the need for costly DWDM.
ETL Systems will also demonstrate its existing StingRay CWDM (Coarse Wavelength Division Multiplexing) solution, which combines eight optical signals on a single fibre by using different wavelengths.
They are compatible with the Coarse Wavelength Division Multiplexing (CWDM4) standard that specifies four lanes of 25 Gbps optically multiplexed onto and demultiplexed from duplex single mode fiber.
