Abstract
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.
Claims6
A system in a data center, the system comprising:
- one or more first electro-optical devices, configured to transmit or receive first optical communication signals having a first carrier wavelength of about 850 nm for internal communication within the data center;
- one or more second electro-optical devices, configured to transmit or receive second optical communication signals having a second carrier wavelength of about 1310 nm for external communication with a remote data center;
- an optical connector for interfacing with the remote data center;
- and
- a universal multi-core fiber (UMCF) interconnect, comprising:
- multiple optical fiber cores configured to simultaneously (i) transfer one or more of the first optical communication signals among the first electro-optical devices, using multi-mode propagation, for the internal communication and (ii) transfer one or more of the second optical communication signals between the second electro-optical devices and the connector, using single-mode propagation, for the external communication;
- and
- a shared cladding enclosing the multiple optical fiber cores;
- and
- wherein each of the multiple optical fiber cores are disposed equidistantly over a circular perimeter of a cross-section of the UMCF interconnect.
A method for optical communication in a data center, the method comprising:
- using one or more first electro-optical devices, transmitting or receiving first optical communication signals having a first carrier wavelength of about 850 nm for internal communication within the data center;
- using one or more second electro-optical devices, transmitting or receiving second optical communication signals of about 1310 nm having a second carrier wavelength for external communication with a remote data center;
- and
- using a universal multi-core fiber (UMCF) interconnect that comprises multiple optical fiber cores and a shared cladding enclosing the multiple optical fiber cores, simultaneously (i) transferring one or more of the first optical communication signals among the first electro-optical devices, using multi-mode propagation, for the internal communication and (ii) transferring one or more of the second optical communication signals between the second electro-optical devices and a connector, using single-mode propagation, for the external communication;
- and
- wherein each of the multiple optical fiber cores are disposed equidistantly over a circular perimeter of a cross-section of the UMCF interconnect.
