Description

SFF-8639 68P to SFF-8639 68P Internal Cable Assembly – High-Speed PCIe/SAS Interconnect for U.2 Storage Integration

The SFF-8639 68P to SFF-8639 68P internal cable assembly is a high-performance solution designed for direct connectivity between U.2 (SFF-8639) interfaces in enterprise-grade storage systems. Supporting both PCIe Gen3 (8GT/s) and Gen4 (16GT/s) data rates, as well as SAS 3.0 (12G) and SAS 4.0 (24G) protocols, this cable enables reliable, high-bandwidth communication between host controllers, backplanes, and NVMe/SAS drives.

Key Features:

• Connector Configuration:
  • SFF-8639 68P plug to SFF-8639 68P plug
  • Available in two variants:
    • With mounting holes for secure chassis integration
    • Without mounting holes for streamlined, low-profile installations
• Internal Cable Assembly: Designed for use within server chassis, storage enclosures, and embedded platforms
• Wire Gauge Range: Supports AWG 30 to AWG 28, balancing flexibility and signal integrity
• Controlled Impedance:
  • 85 ohm for PCIe lanes
  • 100 ohm for SAS lanes
• High-Speed Data Transfer:
  • PCIe Gen3 (8GT/s) and Gen4 (16GT/s) per lane
  • SAS 3.0 (12G) and SAS 4.0 (24G) compatibility
• Robust Shielding: Provides excellent EMI/RFI protection for stable, high-speed signal transmission
• RoHS Compliant: Manufactured in accordance with environmental standards for hazardous substances

Applications:

• Enterprise Servers: Connects U.2 NVMe or SAS SSDs to host controllers or backplanes
• Storage Appliances: Enables high-throughput internal routing for hybrid NVMe/SAS configurations
• Data Centers: Supports scalable, low-latency storage architectures with flexible cable options
• RAID & JBOD Enclosures: Facilitates efficient drive-to-host communication with secure or compact connector mounting
