ST-DAC-QSFPDD-2*QSFP28-1.5

QSFP-DD to 2× QSFP28 Breakout DAC — 1.5m, Built for In-Rack Links

The Sate Optics ST-DAC-QSFPDD-2*QSFP28-1.5 is a 200G to 2× 100G breakout direct attach copper cable, factory-terminated with QSFP-DD to 2× QSFP28 connectors and cut to 1.5m (5ft) — sized for links inside one rack.

Why This Module

• One port, 2 links: a single 200G switch port fans out to 2× 100G — dense breakout wiring without separate transceivers

• 1.5m in-rack reach: spans stacked switches and the servers in the same cabinet, with slack to route neatly

• Factory-terminated and plug-and-play: both ends arrive as one tested assembly — plug in, link up, with lower latency than an optical hop

• Compatible with your platform — coded for major networking platforms, including Cisco, Juniper, Arista, Huawei, Nokia, H3C and ZTE; 100% tested before shipment.

Where It Fits

• Top-of-rack switching with servers cabled straight into the switch above them

• Stacked and clustered switches patched inside one cabinet

• Replacing transceiver pairs where the run is short enough for copper — lower cost, lower power, nothing to clean or pair
