Examples include IDC Cable Assemblies, D-Sub Cable Assemblies, SCSI Cables, VHDCI Cables, Camera Link Cables, DIN Cables, and PCIe Riser Cables. The MDR cable types are not single-type connectors; they come in several sizes: 26 Pin, 36 Pin, 50 Pin, and 68 Pin. The MDR cable distance limitation for LVDS and high-speed signal Transmission is directly related to these factors. Likewise, deciding what to substitute for the SCSI HD68 connector cable with an MDR connector requires understanding that “SCSI” is a system protocol, not a connector geometry. A twisted pair with impedance control is important in an MDR cable to control signal reflection.
