Abstract:
1. A method for interconnecting line card chassis of a data communications system, comprising: providing a fabric card chassis having a set of fabric cards and a first optic adaptor optically coupled to a corresponding fabric card of the set of fabric cards, the first optic adaptor having a first set of pathways configured to carry a signal between the fabric card and each line card chassis of a first plurality of line card chassis; removing the first optic adaptor from the fabric card chassis to optically decouple the first optic adaptor from the corresponding fabric card of the set of fabric cards; and attaching a second optic adaptor to the fabric card chassis to optically couple the second optic adaptor to at least two fabric cards of the set of fabric cards of the fabric card chassis, the second optic adaptor being distinct from the first optic adaptor and the second optic adaptor having a second set of pathways configured to carry a signal between the at least two fabric cards of the set of fabric cards and any line card chassis of the first plurality of line card chassis and any line card chassis of a second plurality of line card chassis.
