This 40G QSFP+ cable 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 active optical cable (AOC) is fully hot-pluggable and supports 40 Gigabit Ethernet applications connected through QSFP+ (Quad Small Form-Factor Pluggable) ports. The AOC cable is lighter and more flexible than QSFP+ direct-attach cables which makes it ideal for installation in tight spaces and over longer distances. Designed for high-speed interconnects, this low-power, low-latency optical cable is ideal for applications such as point-to-point across-rack network switch or server connections.
