Juniper QFX-QSFP-DAC-3M Compatible - QSFP+
Direct Attach Cable - 3 m (9.8 ft.)
Product ID: QFXQSFPDAC3M
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 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, supporting short-distance applications such as point-
to-point in-rack and across-rack network switch or server connections.
Backed by a StarTech.com 2-year warranty, the QFXQSFPDAC3M is a reliable replacement cable for the
