FCI, a leading manufacturer of high speed IO cable assembly and connector systems, has developed cabling solutions utilizing the ExaMAX connector technology that delivers up to 40Gb/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 minimized 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.
Besides th 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 their 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.
