ST-DAC-QSFPDD-2*QSFP28-2.5

QSFP-DD to 2× QSFP28 Breakout DAC — 2.5m, Built for Rack-to-Rack Links

The Sate Optics ST-DAC-QSFPDD-2*QSFP28-2.5 is a 200G to 2× 100G breakout direct attach copper cable, factory-terminated with QSFP-DD to 2× QSFP28 connectors and cut to 2.5m (8ft) — sized for links between neighbouring racks.

Why This Module

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

• 2.5m rack-to-rack reach: crosses to the neighbouring cabinet with room for overhead or underfloor routing

• 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

• Rack-to-rack uplinks between neighbouring cabinets in the same row

• Middle-of-row aggregation over short copper runs

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