Ubiquiti UACC-Uplink-SFP28-0.3M InfiniBand/fibre optic cable White 0.3m SFP28

The Ubiquiti UACC-Uplink-SFP28-0.3M is a 0.3 m InfiniBand/fibre optic cable with SFP28 connectors on both ends, designed for high-speed uplink and device-to-device interconnects. It supports seamless 1G SFP, 10G SFP+, and 25G SFP28 links and is intended for use in networking environments such as data centers and enterprise racks.

Advantages

This direct attach cable provides auto link optimization for compatible UniFi devices, reducing manual configuration. With SFP28 terminations the cable supports 25G performance while remaining backward compatible with 10G SFP+ and 1G SFP ports. Its short 0.3 m length minimizes signal attenuation and helps maintain tidy rack layouts.

Suitable for

• Server-to-switch uplinks in data centers
• Switch-to-switch connections within network racks
• High-density enterprise networking where short, reliable links are required

Key specifications

• Manufacturer: UBIQUITI
• Model / MPN: UACC-UPLINK-SFP28-0.3M
• Length: 0.3 m
• Connector type: SFP28 on both ends (compatible with SFP+ and SFP ports)
• Cable type: InfiniBand / fibre optic direct attach
• Supported link rates: 1G, 10G, 25G

How to use

Insert each SFP28 connector into the corresponding SFP/SFP+ or SFP28 port until it clicks into place. Ensure both connected devices are powered and configured to recognize the link speed automatically or set the appropriate port speed in device settings. Route the 0.3 m cable to avoid sharp bends and secure it to prevent strain on the connectors.

Recommendations

Use this cable for short-distance uplinks inside racks or between adjacent devices. Confirm device compatibility with SFP28 modules and enable auto-negotiation where available; avoid using the cable beyond its intended 0.3 m span and protect connectors from dust when not in use.
