Product information

Description

The StarTech.com EX-QSFP-40GE-DAC-50CM is a 0.5 m passive Twinax QSFP+ to QSFP+ direct-attach copper cable engineered for 40 Gigabit Ethernet connections. Compatible with Juniper®-style QSFP+ ports and designed to meet MSA industry standards, this low-power, low-latency cable provides a compact, hot-swappable solution for short-distance high-speed links between switches, routers and servers.

Advantages

The cable is hot-swappable to minimize network downtime during upgrades or replacements. It is manufactured and tested to be compatible with Juniper®-compatible QSFP+ ports and is backed by StarTech.com lifetime warranty and free multilingual technical support.

How to use

Insert each QSFP+ connector into the corresponding QSFP+ port on the devices to be linked (for example, switch-to-switch or switch-to-server).
