Description

The Sopto SPH-QSFP+Cx 40G Passive DAC is a next-generation copper interconnect designed to support 40 Gbps full-duplex throughput between QSFP+ interfaces. By eliminating the need for separate optical transceivers and fiber, this passive DAC offers a cost-efficient, low-power solution for high-density network environments.

Built to comply with SFF-8436 standards, the SPH-QSFP+C ensures broad compatibility with major networking vendors. Its hot-pluggable QSFP+ connectors enable seamless, plug-and-play integration in active racks, while its passive copper design ensures ultra-low power consumption and high reliability.

Available in various lengths (typically from 1 m to 7 m, depending on AWG), the series is best suited for short-distance applications such as switch-to-switch uplinks, server interconnects, and storage clustering. With durable PVC jacketing and conductor options (AWG24 / AWG30 depending on the model), it provides the flexibility and reliability required for mission-critical deployments.

The Sopto SPH-QSFP+C is a trusted choice for data center, enterprise, and service provider networks looking for performance and efficiency in high-speed copper interconnects.
