PCIe Gen3 iPass x8 to iPass x8 Copper Cable

PCIe Gen3 iPass x8 to iPass x8 Copper Cable

The PCIe Gen3 iPass x8 to iPass x8 Copper Cable is a high‑performance direct‑attach interconnect designed for internal or external PCIe connections within servers, storage systems, and high‑performance computing platforms. Featuring identical iPass x8 connectors on both ends, this cable preserves the full 8‑lane PCIe link width, supporting data rates up to 8.0 GT/s per lane (PCIe Gen3) while remaining backward‑compatible with Gen2 and Gen1. Engineered with low‑loss twin‑axial conductors, precision impedance control, and comprehensive multi‑layer shielding, it delivers exceptional signal integrity over practical cable lengths. The passive copper design ensures near‑zero latency and minimal power consumption, making it an ideal solution for connecting root complexes to expansion cards, backplanes, or external device enclosures that require a reliable, high‑bandwidth x8 interface.

Features

• PCIe Gen3 Compliance – Fully supports PCI Express 3.0 specifications with data rates up to 8.0 GT/s per lane, while remaining backward‑compatible with PCIe 2.0 and 1.0 for seamless integration into mixed‑generation systems.
• x8 to Dual x4 Breakout – Efficiently bifurcates a single x8 host link into two independent x4 external channels, allowing direct connection to two separate devices or enclosures via standard SFF‑8088 external ports.
• External Mini SAS SFF‑8088 Connectors – Uses the industry‑standard SFF‑8088 external connector on both output ports, featuring threaded screw‑lock or push‑pull latching for secure cable retention in external cabling environments.
• Superior Signal Integrity – Precision‑matched differential pairs, low‑loss 30 AWG twin‑axial conductors, and multi‑layer shielding (individual pair foil + overall braid and outer foil) minimise insertion loss, crosstalk, and electromagnetic interference, ensuring clean eye diagrams at PCIe Gen3 speeds.
• Passive Copper Design – No active retimers or redrivers are used, resulting in near‑zero added latency, minimal power consumption, and simplified system integration.
• Hot‑Plug Capability – Supports PCIe hot‑plug and surprise removal, enabling dynamic connection and disconnection of external devices without requiring a system reboot.
• Flexible and Durable Cable Jacket – The cable is designed with a flexible yet rugged outer jacket that facilitates neat routing through cable management trays and tight bends in rack‑mounted systems, while protecting against environmental stress.
• Wide Operating Temperature Range – Rated from -20°C to +85°C, suitable for demanding data centre and industrial deployments.

Applications

• External Storage Expansion – Connect a server or workstation equipped with an iPass x8 host port to external JBODs, RAID arrays, or NVMe drive enclosures that utilise SFF‑8088 input ports, enabling high‑capacity, low‑latency storage extension.
• GPU and Accelerator Clusters – Link host systems to external GPU or FPGA expansion chassis, providing high bandwidth for AI training, 3D rendering, and scientific simulations that demand external PCIe resources.
• PCIe Test and Development – Facilitate prototyping and validation of PCIe devices by providing convenient external ports for debug and performance measurement without opening the system chassis.
• Data Centre Rack Integration – Deploy in rack‑scale architectures where external PCIe resources (e.g., smart NICs, accelerators) are located in separate trays or drawers, connected via external cabling for flexibility, serviceability, and space optimisation.
• High‑Performance Workstations – Used in content creation, virtual reality, and engineering workstations that require external GPU or storage expansion while maintaining high throughput and low jitter.
• Custom System Integration – Ideal for system integrators needing to extend PCIe signals outside the main enclosure for proprietary modules, custom I/O boxes, or specialised peripherals that use the SFF‑8088 interface.
