DAC cable BlueOptics EQPC1HPC010C0100 compatible BlueLAN QSFP28 direct-attach copper 1.0 m

BlueOptics EQPC1HPC010C0100 compatible BlueLAN QSFP28 direct-attach copper (DAC) cable, 1.0 m, is a pre-terminated copper interconnect designed for short-reach, high-bandwidth links. Intended for installation between QSFP28 ports on switches, routers and server NICs, this 1.0 m DAC cable supports 100 Gbps-class data transmission with low latency and lower power consumption compared with active optical solutions. The cable is suitable for dense rack and top-of-rack environments where reliable, cost-effective connectivity is required for high-speed networking equipment.

Advantages

This QSFP28 DAC cable offers plug-and-play connectivity with pre-attached QSFP28 connectors, eliminating the need for transceivers and simplifying installation. Its passive copper construction provides predictable latency and reduced power draw, making it energy-efficient for short inter-rack and intra-rack links. The 1.0 m length minimizes excess cable slack in high-density racks and helps maintain neat cable management. Compatibility with standard QSFP28 ports ensures interoperability with a wide range of switches, routers and NICs that support direct-attach copper connections.

Suitable for

• Short-reach connections between QSFP28 ports in data center racks
• Server-to-switch and switch-to-switch links within the same rack or adjacent racks
• High-throughput applications requiring 100 Gbps-class connectivity
• Environments where low latency and reduced power consumption are priorities

Key specifications

• Connector type: QSFP28 on both ends
• Length: 1.0 m
• Cable type: Direct-attach copper (DAC), passive
• Supported data rate: 100 Gbps-class links
• Typical use: Short-reach, intra-rack and adjacent-rack interconnects

How to use

Plug the QSFP28 connectors into the corresponding QSFP28 ports on your networking devices, ensuring the latch engages and the cable is seated securely. Route the cable to avoid tight bends and interference with other cables or airflow paths. After insertion, verify link status on the connected devices and check for operational speed and error-free transmission via management interfaces. For removal, depress the connector latch before pulling straight out to avoid damaging the port or connector.

Usage recommendations

Use this 1.0 m DAC cable for short, direct connections inside racks or between adjacent racks where QSFP28 ports are available. Maintain bend radius recommendations from equipment vendors, avoid kinking, and keep the cable clear of hot airflow from servers. For longer runs or when optical isolation is required, consider fibre-optic transceivers and cabling instead.
