## Summary description

CBO QSFP28-DAC-1M is a 1-meter passive copper direct attach cable (DAC) with QSFP28 connectors, supporting 100Gbps data rates. Designed for short-reach interconnects in data centers and network racks, it provides low-latency, high-throughput links between switches, servers and storage. The fixed-length passive design reduces power consumption and simplifies rack cabling.

## Long description

The BlueOptics DAC cable CBO QSFP28-DAC-1M is a 1‑metre passive copper direct attach cable with QSFP28 connectors designed for 100Gbps short‑reach interconnects. It provides a fixed‑length, low‑latency link between QSFP28 ports in switches, servers and storage systems within racks and adjacent racks in data centre environments. The passive copper design uses no active electronics in the cable, reducing power consumption and simplifying cable management for dense deployments.
Advantages
This DAC cable offers 100Gbps data throughput over a 1 m fixed length with QSFP28 form factor compatibility, ensuring predictable performance for short-distance connections. The passive copper construction lowers power draw compared with active optical options and avoids the need for additional transceiver modules, which can simplify inventory and reduce total cost of ownership. Its robust QSFP28 connectors ensure reliable mating with standard QSFP28 ports and support hot‑plug operation typical in modern networking equipment.
Suitable for
 Short‑reach interconnects between top‑of‑rack switches and adjacent servers
 Direct links between switch-to-switch connections within the same rack
 High‑throughput links for storage arrays and compute nodes in data centres
 Environments where low latency and reduced power consumption are required
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: Passive copper direct attach
 Maximum data rate: 100 Gbps
 Length: 1 metre
 Intended use: Short‑reach rack and adjacent rack interconnects
 Latency: Low, suitable for latency‑sensitive applications
How to use
Insert each QSFP28 connector into compatible QSFP28 ports on the devices to be connected, ensuring correct orientation and a secure click engagement. The cable is designed for hot‑plug operation; connect or disconnect while devices are powered on if supported by the equipment. Route the cable within the rack to avoid sharp bends and excessive tension; maintain the specified 1 m length without extensions or splices. Verify link status on both devices and confirm negotiated speed and health using the host equipment management interfaces.
Usage recommendations
For reliable operation, use the cable for intra‑rack or adjacent‑rack connections up to 1 m. Avoid running the cable through power-dense or high‑EMI pathways and keep bend radius within vendor guidelines. When replacing transceivers or cables, confirm QSFP28 port compatibility in switch and server documentation and monitor link status after installation.
