This QSFP+ breakout cable connects a single QSFP+ port to four 10G SFP+ ports and delivers what you need most in your network connections: reliable performance. It's built to MSA specifications and fully tested to ensure seamless compatibility. This passive twinaxial cable is a fully hot-pluggable, direct-attach cable, supporting 40 Gigabit Ethernet applications connected through QSFP+ (Quad Small Form Factor Pluggable) ports. Designed for short-length, high-speed interconnects, this low-power, low-latency Twinax cable is a cost-effective alternative to fiber-optic cable assemblies. It supports short-distance applications such as point-to-point in-rack and across-rack network switch or server connections, for up to four 10G SFP+ devices.
