The SFF-8643 connector is a compact, high-density interface for Serial Attached SCSI (SAS) and Serial ATA (SATA) devices. It supports up to 4 differential signal pairs (lanes), allowing for multiple data paths within a single connector. This makes it ideal for high-bandwidth applications like connecting SAS expanders, RAID controllers, or SAS/SATA hard drives and solid-state drives (SSDs). | The cable is rated for 12 Gigabits per second (Gbps) data transfer speed per lane, which translates to a total aggregate bandwidth of 48 Gbps (12 Gbps × 4 lanes) across the entire cable. This high throughput ensures efficient data transfer for demanding storage applications requiring fast access times and large data volumes. | The cable measures 0.3 meters (or 0.9 feet) in length, making it a short-range interconnect solution suitable for close-proximity connections within a rack, chassis, or server. Shorter cables generally exhibit better signal quality and lower latency compared to longer ones, especially at higher data rates. | The specified impedance of 100 Ohms is a critical electrical characteristic that ensures proper signal integrity and minimizes signal loss or distortion over the length of the cable. Maintaining a consistent impedance throughout the cable and matching it to the connected devices is crucial for optimal performance at high speeds. | The cable is 0.3m(0.9ft) long, excluding the connector. Please pay attention to the distance between the devices to avoid the cable being too short.
