InfiniBand/kuitu-kaapeli Ubiquiti UACC-Uplink-SFP28-0.15M

The Ubiquiti UACC-Uplink-SFP28-0.15M is a direct-attach InfiniBand/fibre optic cable with SFP28 connectors at both ends and a cable length of 0.15 meters. It is intended for high-speed uplink connections between UniFi devices, supporting 1G SFP, 10G SFP+, and 25G SFP28 interconnects with auto link optimization for seamless negotiation and stable data transmission.

Advantages

This SFP28 direct-attach cable delivers low latency and high throughput in a compact 0.15 m form factor. Built with SFP28-compatible terminations, it ensures physical compatibility with SFP, SFP+ and SFP28 ports on compatible UniFi hardware and performs auto link optimization to simplify link establishment. The short length reduces signal attenuation and is suitable for short-reach rack or switch-to-switch uplinks.

Suitable for

• Short-reach uplinks between UniFi switches and routers
• High-performance computing clusters requiring low latency
• Data center top-of-rack connections where 0.15 m cable length is sufficient

Key specifications

• Brand: UBIQUITI
• Model / MPN: UACC-Uplink-SFP28-0.15m
• Connector type: SFP28 (both ends)
• Supported link speeds: 1G (SFP), 10G (SFP+), 25G (SFP28)
• Cable type: Direct attach InfiniBand / fibre optic
• Length: 0.15 m

How to use

Insert the SFP28 connectors into the SFP/SFP+/SFP28 ports of the UniFi devices until they latch. Ensure both devices are powered and configured for the desired link speed; the cable supports auto link optimization to negotiate the appropriate speed automatically. Route the 0.15 m cable to avoid sharp bends and secure it within the rack or chassis to prevent strain on the connectors.

Recommendations

Use this short 0.15 m SFP28 direct-attach cable for close-proximity connections within the same rack or adjacent racks. Verify port compatibility with SFP/SFP+/SFP28 interfaces and avoid exceeding the cable’s intended short-reach applications.
