SFF-8643 to SFF-8643 12G Internal Mini SAS HD Cable, with Sideband, for NVMe Backplane/RAID Controller, 100-Ohm, Straight to Straight, 0.3-m(0.9ft)

The SFF-8643 connector is a compact, high-density interface for SAS and SATA devices. It supports up to 4 differential signal pairs (lanes), allowing for multiple data paths within a single connector. It is ideal for high-bandwidth applications like connecting SAS expanders, RAID controllers, or SAS/SATA hard drives and SSDs.
The cable is rated for 12Gbps data transfer speed per lane, translating to a total aggregate bandwidth of 48 Gbps (12 Gbps × 4 lanes) across the entire cable. This high througH-Put ensures efficient data transfer for demanding storage applications requiring fast access times and large data volumes.
The cable measures 0.3m(0.9ft), making it a short-range interconnect solution suitable for proximity connections within a rack, chassis, or server. Shorter cables generally exhibit better signal quality and lower latenthan 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.
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.
