The Juniper JNP-100G-4X25G-5M is a high-performance 100 Gigabit Ethernet Direct Attach Copper (DAC) breakout cable designed to split a single 100GbE QSFP28 interface into four independent 25GbE SFP28 connections. With a 5-meter Twinax copper cable, it provides a cost-effective, low-latency alternative to separate optical transceivers and fiber patch cables.
