Juniper JNP-100G-4X25G-1M QSFP28 to SFP28 DAC 1 m | 100G, Breakout

Turn one 100 GbE uplink into four 25 GbE connections with a 1 m QSFP28 to SFP28 breakout direct attach cable. The Juniper JNP-100G-4X25G-1M is built for environments where port economics matter: one high-speed port on the switch side, four 25 GbE endpoints on the device side, and no separate optical transceivers to manage. This breakout format is a strong fit for leaf-spine fabrics, server aggregation, and high-density rack designs that need efficient fan-out without adding complexity. The 1 m length gives enough reach for practical rack routing while staying short enough to preserve order and reduce slack. That balance matters when you are packing more connectivity into less space. For teams standardizing on 25 GbE access with 100 GbE uplinks, this cable helps align port speed, cabling, and rack layout. It is a straightforward way to extend bandwidth where needed while keeping the physical layer simple and predictable. When the design calls for four 25 GbE paths from a single 100 GbE interface, this is the right cable class for the job.
