FCI’s EyeMax®4X cable assembly, right-angle PCB receptacle, and plug kit offering provides high bandwidth, low-cost copper cable connectivity solutions for linking servers, storage, and other data networking or communication devices. The solution is designed to provide a continuous flow of serial data and eliminate data traffic congestion, from which hardware devices that use a parallel bus structure can suffer.
The EyeMax 4X cable assembly and connector kit from FCI enables high‑speed serial copper links for Infiniband®, 10G Fibre Channel, 10G Base‑CX4 Ethernet, and SFF‑8470 SATA/SAS applications. The product offers a low‑cost alternative to fiber optics with up to 20 Gb/s bandwidth, <4% cross‑talk, and robust EMI shielding.
Technical data includes differential impedance of 100 ± 10 Ω, insertion loss up to 10 dB at 1.25 GHz, and environmental limits from –10 °C to 60 °C. Part numbers for cable assemblies, plug kits, and board‑mount receptacles are listed, along with a capability matrix for various AWG sizes and lengths.
