Patent ID: 8550727

Claim:
A parallel optical communications system comprising: a housing, the housing having a curved surface formed therein adjacent an opening of the housing through which an optical fiber ribbon cable passes, the curved surface including at least first and second curved portions and a transition region in between the first and second curved portions; at least a first parallel optical communications module mounted in the housing; at least a first optical fiber ribbon cable passing through the opening of the housing into an interior space of the housing, the first optical fiber ribbon cable being attached on an end thereof to the first parallel optical communications module; and a spring device disposed within the housing, the curved surface of the housing and the spring device comprising an electromagnetic interference (EMI) containment apparatus, the spring device having a curved surface that is generally complementary in shape to a shape of the curved surface of the housing, wherein a length of the first optical fiber ribbon cable is sandwiched in between the curved surface of the housing and the curved surface of the spring device such that the sandwiched length of the first optical fiber ribbon cable has a curved shape that is defined by the curved surfaces of the housing and of the spring device, and wherein the curved shape of the sandwiched length of the optical fiber ribbon cable helps prevent EMI radiation from propagating along the sandwiched length of the first optical fiber ribbon cable and passing through the opening of the housing.
