ST-DAC-800G-OSFP-1

800G OSFP DAC — 1m, Built for In-Rack Links

The Sate Optics ST-DAC-800G-OSFP-1 is an 800G direct attach copper cable, factory-terminated with OSFP to OSFP connectors and cut to 1m (3ft) — sized for links inside one rack.

Why This Module

• Lowest-cost way to link two ports: no transceivers, no fiber — one cable, and a passive DAC draws essentially no power
• 1m 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

• 800G spine and AI-fabric switches with OSFP ports
• GPU and AI cluster interconnects wired on OSFP cages
• In-rack links within a single cabinet
• Typical platforms: Cisco Nexus 9364E-SG2 series, Arista 7060X6 series, Juniper QFX5240, Nokia 7250 IXR and H3C S12500 series, and other 800G switches built on 100G-per-lane ASICs.

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

Every module is covered by a 3-year warranty with lifetime maintenance. Standard lead time is 3–7 days for most products, and samples are available for evaluation.
