MCIO 16x (SFF-TA-1016) Str. 124P to MCIO 16x (SFF-TA-1016) Str. 124P Cable

MCIO 16x (SFF-TA-1016) Str. 124P to MCIO 16x (SFF-TA-1016) Str. 124P Cable

The MCIO 16x (SFF‑TA‑1016) Str. 124P to MCIO 16x (SFF‑TA‑1016) Str. 124P Cable is a high‑performance internal direct‑attach interconnect designed for next‑generation servers, storage systems, and high‑density computing platforms. Featuring identical straight MCIO connectors on both ends, this cable provides a straightforward, low‑profile connection that preserves the full 16‑lane PCIe link width, delivering maximum bandwidth of up to 128 GB/s bidirectional in PCIe 5.0 mode. Both connectors are fully compliant with the SFF‑TA‑1016 specification and support data rates up to 32.0 GT/s, making this cable an ideal solution for high‑throughput, low‑latency internal cabling between host CPUs, GPUs, NVMe storage controllers, accelerators, and backplanes. Engineered with precision‑tuned twin‑axial conductors, tight impedance control, and comprehensive multi‑layer shielding, the cable ensures exceptional signal integrity over practical cable lengths. The passive copper design introduces near‑zero added latency and consumes negligible power, while the flexible cable jacket facilitates neat routing within crowded chassis, improving airflow and simplifying system assembly.

Features

• The cable provides a seamless 16‑lane to 16‑lane connection without any breakout or bifurcation, preserving the full x16 bandwidth for maximum data throughput and ensuring that host and peripheral devices communicate at their highest possible performance.
• Both ends feature straight MCIO 124‑pin male connectors, designed for direct board‑to‑cable mating. The straight orientation offers a compact, low‑profile connection that is ideal for systems where space is at a premium and where a right‑angle exit is not required.
• Each connector incorporates the SFF‑TA‑1016 standard dual‑push‑pull latching mechanism, ensuring a secure, vibration‑resistant connection that prevents accidental dislodgement in high‑shock environments such as rack‑mounted servers and storage arrays. This positive locking also maintains electrical contact integrity over repeated mating cycles.
• The cable is constructed with low‑loss 30 AWG twin‑axial wires, and each differential pair is individually shielded with foil. An overall braid and outer foil shield provide additional protection against electromagnetic interference and crosstalk, minimising insertion loss and signal skew to deliver clean eye diagrams even at PCIe 5.0 speeds.
• As a passive copper assembly, the cable requires no active retimers or redrivers, resulting in negligible added latency and virtually zero power consumption, which is critical for power‑sensitive and latency‑critical applications such as AI training, real‑time analytics, and high‑frequency trading.
• The cable jacket is engineered for flexibility, allowing tight‑radius bends while maintaining signal performance. This flexibility simplifies internal cable routing, improves airflow within the chassis, and reduces mechanical stress on connectors and PCB traces, contributing to overall system reliability.
• Fully compliant with PCIe 5.0 specifications, the cable is backward compatible with PCIe 4.0, 3.0, and earlier generations, enabling seamless integration into legacy and mixed‑generation systems without performance degradation.

Applications

• This cable is ideally suited for internal PCIe connections within servers and workstations where board‑to‑board or board‑to‑card distances require flexible cabling instead of rigid backplanes, particularly when both the host and peripheral connectors are oriented straight.
• It is widely used in high‑performance computing nodes to connect a motherboard or host CPU to a GPU, FPGA, or AI accelerator card, providing the full x16 bandwidth needed for demanding parallel processing tasks such as deep learning, scientific simulations, and 3D rendering.
• In enterprise storage systems, the cable enables reliable connectivity from a host adapter to NVMe drive backplanes, allowing high‑density storage configurations without signal degradation over longer internal runs.
• The straight‑to‑straight design is ideal for systems with ample clearance around the connectors, making it a versatile choice for standard server chassis, tower workstations, and custom enclosures where no angled exit is required.
• System integrators and prototype developers will appreciate the simplicity and reliability of this cable for connecting development boards, test benches, or custom hardware, reducing design complexity and accelerating time‑to‑market.
• Additionally, the cable serves as a direct replacement for other straight MCIO interconnects in upgrades or reconfigurations, offering a high‑performance, drop‑in solution that ensures signal integrity and mechanical compatibility.
