OCuLink SFF-8611 8x to OCuLink SFF-8611 4x * 2

Description

OCuLink SFF-8611 8x to OCuLink SFF-8611 4x * 2 Internal Cable Assembly – High-Speed PCIe/SAS Fanout for Compact System Integration

The OCuLink 8x (SFF-8611) to dual OCuLink 4x internal cable assembly is a high-performance fanout solution designed to split a single high-bandwidth OCuLink 8x interface into two independent OCuLink 4x channels. Engineered for PCIe and SAS signal transmission, this cable is ideal for internal connectivity in servers, storage appliances, and embedded systems requiring flexible multi-port expansion.

Key Features:

• Connector Configuration:
  • OCuLink 8x plug (SFF-8611)
  • 2 × OCuLink 4x plugs (SFF-8611)
• Internal Cable Assembly: Designed for internal routing between host controllers and peripheral modules in compact enclosures.
• Wire Gauge: Uses AWG 34 conductors for fine-pitch, high-density signal transmission.
• Controlled Impedance: Maintains an 85-ohm differential impedance, optimized for PCIe Gen3/Gen4 and SAS 12G protocols.
• High-Speed Data Transfer:
  • Supports up to 16 GT/s per lane for PCIe
  • Enables reliable performance across multiple storage or accelerator channels
• Dual Port Fanout: Efficiently distributes bandwidth from a single OCuLink 8x source to two OCuLink 4x targets.
• Compact & Efficient Design: Ideal for space-constrained environments requiring multi-device connectivity.
• Robust Shielding: Provides excellent EMI/RFI protection for signal integrity in high-speed systems.
• RoHS Compliant: Manufactured in accordance with environmental standards for hazardous substances.

Applications:

• Enterprise Servers: Connects OCuLink-enabled host adapters to dual PCIe or SAS targets such as NVMe drives or expanders.
• Storage Appliances: Facilitates internal fanout from a single controller to multiple storage modules.
• Embedded Systems: Provides scalable connectivity for industrial platforms with limited space and high data throughput needs.
• AI & HPC Platforms: Enables high-bandwidth links to GPUs, FPGAs, or other accelerators from a single OCuLink interface.
• Data Centers: Supports modular, high-performance architectures with flexible internal cabling options.
