FCI has developed cabling solutions making use of ExaMAX™ plug connection technology, covering a band width of up to 40 Gb/s.

The  revolutionary ExaMAX™ I/O plug connector design combines a new plug face design technology, which reduces the contact projection (terminal stub) and earth mode resonances, and with an optimized cable connection which cuts down impedance differences and signal losses.

ExaMAX™ cable assemblies take advantage of the obvious advantages of the ExaMAX™ contact system – symmetrical differential pairs, and contact face with minimized contact projection - and combines these with a carefully monitored and supervised cabling process, guaranteeing minimum influence on the signal flow and the signal integrity capacity as a whole. Crosstalk, offset, and impedance mismatch are minimized over the whole of the cable management, the cable connections, and the cable stress-relief areas, so as to ensure the high bandwidth capability of the cable sets. The first samples of the cables demonstrate full electrical conformity with the OIF-CEI-25G-LR industry standard specification.

“ExaMAX™ cable assemblies are an extension of the ExaMAX™ product family. The performance, simplicity, and cost-effectiveness of the ExaMAX™ system makes it the ideal cabling solution, providing high connection density and high signal I/O flow on limited board space”, says Jim David, HSIO Portfolio Director at FCI. “System hardware designers with applications such as internal point-to-point or rack-to-rack cabling, rear-wall openings, or rear-wall cabling applications, where signal loss is one of the main concerns, will find a  really efficient solution with ExaMAX™ cables.”

In addition to the excellent signal integrity capacity of the ExaMAX™ I/O system, these cabling assemblies provide the flexibility for connecting standard twin-axial or flat cable twin-axial cable designs, such as are offered by 3M, and their products from the SL8800 Series. These cables use multiple waver as the basis for the cable design, and that means that a large number of varied differential pairs can be used easily, with extraordinary bending radii and cable routing possibilities.
