BlueOptics JNP-100G-DAC-5M-BL InfiniBand/fibre optic cable QSFP28 5m Male/Male

The BlueOptics JNP-100G-DAC-5M-BL is a 5-meter QSFP28 direct attach cable (DAC) designed for short-reach high-speed links in data centers and rack environments. As a passive twinax copper cable with QSFP28 male connectors on both ends, it supports 100GBase-CR4 electrical signaling and is intended for connecting switches, routers, servers and storage hardware that accept QSFP28 direct attach twinax connections. The cable is MSA-compliant and engineered for minimal latency and reliable 100 Gbit/s connectivity over a 5 m distance.

Advantages

The cable offers low power consumption and low latency typical of passive twinax DACs, together with straightforward plug-and-play operation in compatible hardware. Construction uses industry-standard components and MSA-compliant QSFP28 interfaces to ensure compatibility with major networking platforms that support 100GBase-CR4 direct attach connections. The 26 AWG twinax conductor and robust connector housings provide mechanical stability for rack-to-rack and in-rack links.

How to use

Install the BlueOptics QSFP28 DAC by inserting each QSFP28 connector into the device transceiver slot until it latches. Ensure both connected devices support passive 100GBase-CR4 DACs and that ports are configured for matching link speed and protocols. Verify link status and error counters after insertion. For removal, release the connector latches and pull straight out to avoid stressing the cable assembly. Use appropriate strain relief and route the cable to avoid tight bends; the cable is intended for short, direct connections within racks or between adjacent racks.

Recommendations

Use this passive 100G QSFP28 DAC for short-distance, high-throughput links where power efficiency and low latency are required; confirm hardware compatibility with passive DAC operation and consult equipment vendor documentation if vendor-specific compatibility lists are needed.
