## Summary description

Copper direct attach cable (DAC) BlueOptics UACC-DAC-QSFP28-1M provides a 1‑meter QSFP28 connection for 100GBASE‑CR4 links. Constructed with 30AWG conductors, it supports 100 Gigabit Ethernet and Infiniband EDR-compatible deployments where a short, low-latency, cost‑effective interconnect between switches, routers, NICs or storage systems is required.

## Long description

The Direct Attach Cable BlueOptics UACC-DAC-QSFP28-1M 100GBASE-CR4 QSFP28, 30AWG, 1 m is a 1-metre passive copper QSFP28 assembly designed for short-reach 100 Gigabit Ethernet and compatible high-speed interconnects. Built with 30AWG conductors and QSFP28 connectors at both ends, the cable delivers a low-latency, low-power physical link suitable for rack-to-rack or within-rack connections between switches, routers, network interface cards and storage systems. The construction targets environments where cost‑effective, reliable 100GBASE‑CR4 connectivity is required without the need for optical transceivers.
Advantages
The cable offers a compact, plug-and-play solution for establishing 100G copper links with minimal setup. Passive construction keeps power consumption low while the QSFP28 form factor ensures compatibility with equipment supporting 100GBASE-CR4 and related QSFP28 ports. With a 1 m length and 30AWG conductors the assembly provides a predictable electrical path suitable for short-distance, high-throughput applications while avoiding the expense and power overhead of active optical modules.
Suitable for
Short-reach 100 Gigabit Ethernet links in data centre racks
Interconnects between top-of-rack and aggregation switches
Direct connections from servers or NICs to switches supporting QSFP28
High-throughput storage systems and fabric interconnects compatible with 100GBASE-CR4 or Infiniband EDR signaling
When it may not be suitable
This copper direct attach cable is intended for short distances; it is not suitable for long-reach connections or runs that exceed the electrical reach of a 1-metre passive cable. Environments that require optical isolation, fiber cabling, or extended continuous runs should use appropriate optical transceivers and fiber cables instead.
Key specifications
Connector type: QSFP28 to QSFP28
Data rate: 100 Gigabit Ethernet (100GBASE-CR4) compatible
Conductor size: 30 AWG
Length: 1 metre
Cable type: Passive copper direct attach
Compatible signalling: 100GBASE-CR4 and Infiniband EDR-compatible links
How to use
Insert the QSFP28 connectors into the matching QSFP28 ports on the two devices until the latch engages. Ensure both endpoints support passive QSFP28 direct-attach copper connections and the interface is configured for 100G operation. No additional software drivers are required for the cable itself; verify link status and speed in the devices' management interfaces after insertion. Avoid sharp bends and maintain the minimum bend radius specified by the equipment manufacturer to preserve signal integrity.
What to consider before purchase
Confirm both devices have QSFP28 ports that accept passive copper direct-attach cables
Verify that 1 metre length is suitable for your rack or equipment layout
Check that your equipment supports 100GBASE-CR4 or compatible Infiniband EDR signalling
Consider whether optical transceivers or active cables are required for longer reach or different optical isolation needs
Usage recommendations
For reliable performance, use the cable for connections within racks or between adjacent racks, avoid tight bends, and periodically inspect connector ferrules for dirt or damage. Validate link speed and error counters after deployment to ensure the cable meets throughput expectations in your network environment.
