BLUELAN Compatible Ubiquiti UACC-DAC-QSFP28-3M Direct Attach Cable, 100GBASE-CR4, Infiniband EDR, 26AWG, 3 Meter UACC-DAC-QSFP28-3M-BL

Data center engineers deploying Ubiquiti switches and servers often need a reliable, high-speed interconnect for top-of-rack links. The BLUELAN UACC-DAC-QSFP28-3M-BL is a passive Direct Attach Copper (DAC) cable with QSFP28 connectors on both ends, delivering 100 Gbps throughput over a 3-meter length. It is fully compatible with Ubiquiti's UACC-DAC-QSFP28-3M and supports both Ethernet (100GBASE-CR4) and Infiniband EDR protocols, making it a versatile choice for modern high-performance computing and enterprise networking environments.

Key specifications

• Connector type: QSFP28 to QSFP28
• Data rate: 100 Gbps
• Ethernet standard: 100GBASE-CR4
• Infiniband standard: EDR (Enhanced Data Rate)
• Length: 3 meters (9.84 ft)
• Wire gauge: 26 AWG
• Cable material: Copper
• Passive cable (no signal amplification)
• Hot-pluggable: Yes
• Protocol support: Ethernet, Infiniband
• Number of lanes: 4

Why choose it

This DAC cable offers a cost-effective alternative to optical transceivers for short-reach 100G connections. Its passive design means lower power consumption and reduced latency, while the 26 AWG copper conductors ensure signal integrity over the 3-meter span. The QSFP28 connectors are hot-pluggable, simplifying installation and maintenance in dense rack environments.

Ideal use cases

• Top-of-rack switching in data centers
• High-performance computing (HPC) clusters
• Enterprise network backbone links
• Infiniband EDR fabric connections

Good to know

The cable is designed to match Ubiquiti's UACC-DAC-QSFP28-3M specifications, ensuring seamless interoperability with Ubiquiti networking equipment that supports QSFP28 ports. It supports four data lanes, enabling full 100 Gbps throughput when used with compatible hardware.
