DAC cable CBO 100GB-C01-QSFP28, QSFP28 to QSFP28, 100 Gbps, passive, 30 m, BlueLAN

The BlueOptics DAC cable CBO 100GB-C01-QSFP28 is a passive Direct Attach Copper (DAC) assembly designed to link QSFP28 ports at 100 Gbps over a 30 metre span. Pre-terminated and factory-tested, the cable provides a ready-to-install connection for short-reach, high-bandwidth interconnects in data centre racks, switch-to-switch links or server uplinks. The BlueLAN variant is presented in blue jacketing for easy identification and cable management in dense cabling environments.

Advantages

This passive QSFP28 to QSFP28 cable delivers low-latency, high-throughput connectivity without the need for optical transceivers, reducing component count and power consumption. Its pre-terminated ends simplify installation and minimize risk of termination errors. With a 30 m length it covers typical in-rack and adjacent-rack distances while maintaining signal integrity suitable for 100 Gbps links. Durable jacket and strain reliefs support reliable mechanical performance in rack environments.

Suitable for

• Short-reach 100 Gbps links between network switches
• Server uplinks and top-of-rack aggregation in data centres
• High-density cabling runs where colour-coded identification is required
• Laboratory and testbed setups needing predictable, low-latency connections

Key specifications

• Connector type: QSFP28 to QSFP28
• Maximum data rate: 100 Gbps
• Cable type: passive Direct Attach Copper (DAC)
• Nominal length: 30 metres
• Jacket colour: blue
• Typical application: short-reach, rack-to-rack and in-rack interconnects

How to use

Install the cable by inserting each QSFP28 connector into the corresponding port until the latch engages. Ensure both ends are fully seated and that ports on connected equipment are powered down or support hot-plug insertion according to the device manufacturer’s guidance. Route the cable to avoid tight bends and mechanical stress; maintain bend radii recommended for copper assemblies. Verify link status via switch or server management interfaces and test throughput and error rates after installation.

Recommendations

Use this passive DAC cable for distances up to 30 metres within racks or between adjacent racks. Avoid running the cable near sources of electromagnetic interference and do not exceed recommended bend radius. For installations requiring extended reach, optical modules or active DACs should be considered.
