## Summary description

The BlueOptics UACC-DAC-SFP28-3M-BL is a 3-meter InfiniBand/fibre optic cable with SFP28 connectors. It features a male/male configuration, ensuring high-speed data transfer and reliable connectivity for data centers and networking applications.

## Long description

The BlueOptics UACC-DAC-SFP28-3M-BL is a 3-meter direct attach cable (DAC) with SFP28 male connectors at both ends, designed for short-range, high-speed links in racks and between adjacent racks. It implements a passive twinax copper construction compatible with 25GBase-CR and supports InfiniBand, Ethernet, Fibre Channel and related protocols up to 25 Gbit/s over the 3 m length. The cable follows MSA-compliant SFP28 form factor and is supplied in a blue jacket for easy identification.
Advantages
This direct attach cable provides low-latency, low-power connectivity for short-distance interconnects. As a passive 25G twinax solution with 30 AWG conductors, it offers a straightforward physical link without active electronics in the cable, reducing complexity and failure points. The cable is manufactured using components from established suppliers and is tested for compatibility with major hardware platforms that support the SFP28 25GBase-CR standard.
Suitable for
Interconnects between switches, routers and servers within racks or adjacent racks
Short-distance 25 Gbit/s links for Ethernet, FCoE or InfiniBand applications
High-density data centre top-of-rack and spine-to-leaf cabling
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 3 m
Supported data rates: up to 25 Gbit/s
Cable type: passive twinax copper (30 AWG)
Form factor: SFP28, MSA compliant
Colour: blue jacket for identification
How to use
Insert each SFP28 connector into the corresponding SFP28 slot on supported switches, routers or host adapters while the equipment is powered down or following the device vendor's hot-plug guidance. Ensure both ends are fully seated and locking latches engage. Verify link status in the host device's interface to confirm successful negotiation at 25 Gbit/s or the supported protocol. For best results, avoid sharp bends and maintain the recommended bend radius for twinax cables.
Usage recommendations
Use this cable for short-range rack-level connections where a cost-effective, low-latency 25G link is required. Confirm that the network hardware explicitly supports passive SFP28 DACs and the 25GBase-CR or compatible protocol before deployment. Store and route the cable to avoid tight bends and mechanical strain to preserve lifetime and performance.
