Abstract
Technologies for optical communication in a rack cluster in a data center are disclosed. In the illustrative embodiment, a network switch is connected to each of 1,024 sleds by an optical cable that enables communication at a rate of 200 gigabits per second. The optical cable has low loss, allowing for long cable lengths, which in turn allows for connecting to a large number of sleds. The optical cable also has a very high intrinsic bandwidth limit, allowing for the bandwidth to be upgraded without upgrading the optical infrastructure.
Claims20
A system comprising:
- a plurality of network switches, each network switch of the plurality of network switches comprising a plurality of optical connectors;
- a plurality of passive optical cables, wherein each passive optical cable of the plurality of passive optical cables comprises:
- at least two optical fibers;
- a first connector at a first end of the passive optical cable connected to an optical connector of a sled of a plurality of sleds;
- and
- a second connector at a second end of the passive optical cable connected to an optical connector of the plurality of optical connectors of a corresponding network switch of the plurality of network switches,
- wherein each of the plurality of sleds is connected to each of the plurality of network switches by at least one of the plurality of passive optical cables.
