## Summary description

CBO QSFP28-DAC-1M is a 1 metre passive copper Direct Attach Cable (DAC) designed for 100G networking. It uses QSFP28 connectors to provide a low-latency, cost-effective direct connection between compatible switches, servers and network devices within short rack or cabinet distances. Ideal for high-bandwidth interconnects where optical transceivers are not required.

## Long description

The BlueOptics Direct Attach Copper (DAC) Cable CBO QSFP28-DAC-1M is a 1-metre passive copper interconnect engineered for 100G networking. With QSFP28 connectors, this cable provides a direct, low-latency link between compatible switches, routers, servers and network interface cards within the same rack or adjacent cabinets. The design eliminates the need for optical transceivers where short-distance, high-bandwidth connections are required, offering a simple and cost-effective option for data centre interconnects and high-performance compute clusters.
Advantages
This passive DAC cable delivers reduced latency and reliable signal integrity for short-reach 100G links while keeping power consumption low because no active components or optical modules are required. Its fixed 1 m length simplifies cable management in dense rack environments and reduces the need for additional patch panels. The QSFP28 form-factor ensures broad compatibility with equipment that supports direct attach copper for 100 Gigabit Ethernet, enabling straightforward deployment and predictable performance.
Suitable for
Short-reach 100G interconnects within the same rack or neighboring racks
High-density switch-to-switch and switch-to-server connections in data centres
Compute clusters and storage arrays requiring low-latency links
Environments where optical transceivers are unnecessary or cost-prohibitive
Key specifications
Interface: QSFP28 to QSFP28
Length: 1 metre (fixed)
Data rate: 100 Gbps
Cable type: Passive copper direct attach
Typical use: Short-reach, in-rack or adjacent-cabinet connections
Power: No external power required for the cable
How to use
Ensure that both devices support QSFP28 direct attach copper connections and are configured for 100G operation. With devices powered down or following hot-plug guidelines from the equipment manufacturer, align and insert each QSFP28 connector into the corresponding port until the latch engages. Verify link status and speed through the device management interface and adjust port settings if necessary. For removal, release the latch and pull the connector straight out to avoid stressing the port or cable.
Usage recommendations
Use this 1 m passive DAC cable for short, high-bandwidth links inside racks or between adjacent cabinets. Avoid sharp bends, excessive pulling force, and exposure to liquids or extreme temperatures. For longer distances or connector type mismatches, select an appropriate optical transceiver and fibre cable instead.
