MACROREER 400GBase-CU QSFP-DD to QSFP-DD direct attach cable that is MSA compliant and operates over passive copper, with a maximum reach of 1.5m. It has been uniquely serialized, programmed, and tested for data-traffic and application to ensure 100% compliance and functionality. Our cables comply with MSA standards, and we offer a limited lifetime warranty. The 400G QSFP-DD DAC is designed with ultra-low loss materials, twisted pair cable 8 wires, and shell extension construction for superior mechanical properties and bending performance. It is suitable for very short links and provides a cost-effective way to establish a 400-Gigabit link between QSFP-400G ports of switches/routers within racks and across adjacent racks. It is compatible with various protocols and has a data rate of up to 400Gb/s with a power consumption of ≤0.1W.
This is a hot-swappable input/output device that plugs into a 400G Ethernet Multi-Vendor QSFP-DD port. It is 100% compatible with other IEEE-compliant 400GBASE interfaces where applicable and has been tested on Multi-Vendor QSFP-DD 400G ports for superior performance, quality, and reliability. The device is compliant with IEEE 802.3 and Multi-Vendor MSA standards, with high-speed electrical and optical interfaces compliant to IEEE 802.3, QSFP-DD MSA CMIS Rev4.1, OIF 56G PAM4, IEEE 802.3, and 100G Lambda MSA. The QSFP-DD port is backward compatible with QSFP+, QSFP28, and QSFP56 modules, and has a maximum power consumption of 0.1W per end with near zero-latency delays. The device has been tested in targeted switches for superior performance, quality, and reliability, and is compliant to QSFP-DD MSA CMIS Rev4.0, OIF 56G PAM4. The minimum bend radius is 55mm for flexible routing, and it offers a cost-effective way for short links. The device has an 8x50G PAM4 retimed 400GAUI-8 electrical interface and is hot-pluggable QSFP-DD MSA compliant. It has low insertion loss and ultra-low crosstalk for improved performance.
