FCI Cabled Solutions up to 40 Gb/s with ExaMAX Connector Technology

FCI has developed cabling solutions utilizing the ExaMAX connector technology that deliver up to 40 Gb/s bandwidth capability. The ExaMAX IO connector design combines a new contact interface design technology that significantly decreases terminal stub and ground-mode resonances with an optimized cable termination that minimizes impedance mismatch and signal loss.

The ExaMAX cable assemblies leverage the inherent advantages of the ExaMax contact system – balanced differential pairs minimize electrical stub contact interface, while combining it with a highly controlled cable termination process that assures minimal impact to the signal path and the overall signal integrity performance. Crosstalk, skew, and impedance mismatch are minimized throughout the wire management, wire termination, and wire strain relief areas to assure the high bandwidth capability of the cable assemblies. Initial cable samples exhibit full electrical compliance to the OIF-CEI-25G-LR industry standard specification.

“The ExaMAX cable assemblies are an extension to the ExaMAX family of products. The performance, simplicity, and cost-effectiveness of the ExaMAX system makes it an ideal cable assembly solution that combines high port density/signal IO throughput within a compact board real estate,” said Jim David, HSIO portfolio director for FCI. “System hardware designers with applications like internal point-to-point or rack-to-rack cabling, backplane pass-through, or cabled backplane applications, where signal loss is a major concern, will find the ExaMAX cables to be a viable option.”

Besides the excellent signal integrity performance exhibited by the ExaMAX IO system, the cable assemblies have the flexibility to terminate standard twin-axial or ribbonized twin-axial cable constructions like those offered by the 3M corporation and its SL8800 series products. These cables utilize multiple wafer counts as a basis for the cable construction and therefore various differential pair counts can be easily accommodated with superior cable bend radius and cable routing capability.
