Meritec’s HERCULES Interconnection System embedded in the mating rugged circular MIL-38999 shell, provides both a durable and high bandwidth interconnect scheme suitable for many Military and Aerospace ruggedized high bandwidth applications, not previously accommodated by industry standards.
The HERCULES is the first of the High BandWidth (HBW) Family to be released in MIL-38999 Series III sizes: 9, 13, 17 & 23.
Meeting protocols such as USB 2.0 & 3.0, IB, SAS, SATA, Serial I/O, PCIe, dependent on the shell size, you have many build options. While running at 10Gb/s per pair with up to 44 differential pairs, you do the math.
