ST-DAC-OSFP-2*OSFP-3

OSFP to 2× OSFP Breakout DAC — 3m, Built for Rack-to-Rack Links

The Sate Optics ST-DAC-OSFP-2*OSFP-3 is an 800G to 2× 400G breakout direct attach copper cable, factory-terminated with OSFP to 2× OSFP connectors and cut to 3m (10ft) — sized for links between neighbouring racks.

Why This Module

• One port, 2 links: a single 800G switch port fans out to 2× 400G — dense breakout wiring without separate transceivers
• 3m 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
