OPTICAL INTERCONNECTION ASSEMBLY FOR SPINE-AND-LEAF NETWORK SCALE OUT

摘要

An optical interconnection assembly for a spine-and-leaf network is disclosed. The optical interconnection assembly has spine MF components and leaf MF components. The spine MF components are optically connected to spine MF components of spine switches via spine patch cords. The leaf MF components are optically connected to leaf MF components of leaf switches via leaf patch cords. An array of duplex fiber optic cables serves to optically connect every spine MF component to every leaf MF component so that every spine switch is optically connected to every leaf switch. The optical interconnection assembly facilitates network scale out without the multifiber connections having to be broken up into multiple duplex connections using duplex fiber optic cables.

1. An optical interconnection assembly for optically connecting one or more spine switches to one or more leaf switches in a spine-and-leaf (S/F) network, comprising:
an array of duplex fiber optic cables, wherein each of the duplex fiber optic cables has a first end and a second end, and wherein each duplex optical fiber cable forms a parallel channel having a data rate D; a plurality of ML of leaf multi-fiber (MF) components, wherein each of the leaf MF components optically connects to the first ends of certain ones of the duplex fiber optic cables, and wherein each leaf MF component provides NL parallel channels and a bandwidth BWL; a plurality of MS of spine MF components, wherein each of the spine MF components optically connects to the second ends of certain ones of the duplex fiber optic cables, and wherein each spine MF component provides NS parallel channels and a bandwidth BWS; and wherein the array of duplex fiber optic cables connects every leaf MF component to every spine MF component to define the NS and NL parallel channels, and wherein BWS=NS·D and BWL=NL·D so that NS/NL=ML/MS.
