The QDD‑4X100G‑2P5M copper breakout direct‑attach cable from Juniper delivers high‑speed 400G connectivity by splitting a single QSFP56 interface into four 100G QSFP28 ports over a 2.5‑meter run. Designed for data‑center and enterprise environments, it offers reliable, low‑latency performance within a standard temperature range of 0–70 °C. The 26‑AWG construction ensures optimal signal integrity and minimal loss, while the rugged, pre‑terminated design simplifies deployment and reduces cable clutter. Ideal for scaling high‑density switches, routers, and servers, this cable supports rapid, cost‑effective expansion without compromising on speed or reliability.
