NSComm 40G QSFP+ to QSFP+ Direct Attach Copper Cable, PVC, up to 7m
40G QSFP+ to QSFP+ Direct Attach Copper Cable (DAC), Passive, up to 7 m (23 ft)
Overview
The NSComm 40G QSFP+ to QSFP+ Direct Attach Copper Cable (DAC) is a low-cost, low-latency interconnect designed for short-distance 40 Gigabit Ethernet links. Built with twinax copper cable and factory-terminated QSFP+ connectors, it provides a plug-and-play alternative to optical transceivers and patch cords for in-rack and adjacent-rack deployments.
The passive version supports lengths up to 7 m (23 ft) without requiring additional power. For longer reaches, active copper versions can extend connectivity with minimal power consumption (< 1.5 W). The cable ensures stable signal integrity, consistent latency, and excellent EMI immunity for dense data center environments.
Compatible Brands
The NSComm 40G QSFP+ DAC is validated for use with devices from Cisco, Huawei, Juniper, Arista, Dell, Intel, Extreme, and more.
