ST-DAC-OSFP-2*OSFP-1.5

OSFP to 2× OSFP Breakout DAC — 1.5m, Built for In-Rack Links

The Sate Optics ST-DAC-OSFP-2*OSFP-1.5 is an 800G to 2× 400G breakout direct attach copper cable, factory-terminated with OSFP to 2× OSFP connectors and cut to 1.5m (5ft) — sized for links inside one rack.

Why This Module

• One port, 2 links: a single 800G switch port fans out to 2× 400G — 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.

Key Specifications

Used In

• One 800G port split into 2× 400G links

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
