Abstract

A system includes a pair of network devices, a universal multi-core fiber (UMCF) interconnect, and a pair of wavelength-division multiplexing (WDM) devices. Each network device includes (i) first optical communication devices configured to communicate first optical signals having a first carrier wavelength and (ii) second optical communication devices configured to communicate second optical signals having a second carrier wavelength. The universal multi-core fiber (UMCF) interconnect includes multiple cores that are configured to convey the first optical signals and the second optical signals between the network devices, using single-mode propagation for the first optical signals and multi-mode propagation for the second optical signals. Each WDM device is connected between a respective network device and the UMCF interconnect and configured to couple the first and second optical communication devices of the respective network device to the cores in accordance with a defined channel assignment.
