Because the promoters of SAS technology are eager to create a complete SAS ecology, so as to launch a variety of SAS connector specifications and shapes of SAS cables (common SAS interface types are introduced), although the starting point is good, but also to the market has brought many side effects, too many types of connectors and cables, which is not conducive to mass production to reduce costs, Also objectively to the user caused a lot of unnecessary trouble. Fortunately, the maturity of the Mini SAS connector has brought us the dawn of simplification, the large stock, SAS external cables are mainly three kinds, that is, the same 8470-8470 and 8088-8088 connectors at both ends, and the different 8470-8088 connectors, of which the latter can have two connection scenarios. Therefore, the possible connection scenario is 4, far less complicated than the internal cable, but will not involve the problem of fan-out, if the SFF-8088 can be unified, should leave a SAS external cable can be, but for the bare wire, currently mainly from the electrical performance to distinguish, divided into 6G and 12G, SAS4.0 24G, But the mainstream production process is still basically the same, today we will share together, Mini SAS bare wire introduction and production process control parameters.
For SAS high-frequency communication lines, impedance, attenuation, loop loss, crosstalk, etc., are the most important transmission indicators, and SAS high-speed transmission lines generally operate at ultra-high frequencies above 2.5GHz. The following table is the main technical parameter requirements for SASA cables in the communication protocol.
