A network device includes an enclosure, a multi-chip module (MCM), an optical-to-optical connector, and a multi-core fiber (MCF) interconnect. The enclosure has a panel. The MCM is inside the enclosure. The optical-to-optical connector, which is mounted on the panel of the enclosure, is configured to transfer a plurality of optical communication signals. The MCF interconnect includes multiple fiber cores for routing the plurality of optical communication signals between the MCM and the panel. The MCF has a first end at which the multiple fiber cores are coupled to the MCM, and a second end at which the multiple fiber cores are connected to the optical-to-optical connector on the panel.

High density optical I/O inside a data center switch using multi-core fibers

A universal multi-core fiber (UMCF) interconnect includes multiple optical fiber cores and a shared cladding. Each of the optical fiber cores is configured to convey first optical communication signals having a first carrier wavelength using multi-mode propagation, and to convey second optical communication signals having a second carrier wavelength using single-mode propagation. The shared cladding encloses the multiple optical fiber cores.

Intra data center and inter data center links using dual-wavelength multimode/singlemode multi-core fiber

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.
