Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a SAS high-speed connector female head. Background Art

[0002] Serial Attached SCSI (SAS) connectors are a mainstream interconnect device for enterprise storage applications. These small form factor (SFF) standard connectors are designed to support differential signaling and drive performance improvements. SAS interface technology is backward compatible with SATA. The SAS system's backplane can connect both dual-port, high-performance SAS drives and high-capacity, low-cost SATA drives. SAS seamlessly integrates with SATA and some SCSI devices. The current SAS 4.0 bandwidth exceeds 16Gb / s, reaching a maximum of 24Gb / s, and is used in servers and storage devices, HDDs, HDD carriers, and SSDs. Currently, some SAS connectors are required to meet the SAS 4.0 transmission standard.
