Cabo DAC BlueOptics DAC-QSFP28-100G-1M-BL 1 m QSFP28 macho/macho

The BlueOptics DAC-QSFP28-100G-1M-BL is a 1-meter direct attach copper (DAC) cable with QSFP28 male connectors on both ends, engineered for 100 Gbps short-reach interconnects in data center and enterprise networking environments. It provides a fixed-length, low-latency link suited for connecting switches, routers and servers where high throughput and reliable physical connectivity are required.

Advantages

This DAC cable offers native support for 100 Gigabit Ethernet with QSFP28 interfaces, delivering low power consumption and minimal signal latency compared with active optical transceivers. The 1 m length reduces cabling clutter in dense rack deployments and simplifies port-to-port connections. Its factory-terminated, pre-tested construction ensures consistent electrical performance and plug-and-play compatibility with equipment designed for QSFP28 direct-attach links.

Key specifications

How to use

Insert each QSFP28 connector firmly into the corresponding port on your network devices until the latch engages. Ensure both devices support 100 Gbps QSFP28 direct-attach connections and that firmware or vendor compatibility requirements are met. For optimal signal integrity, avoid tight bends and sharp kinks in the cable and route it to minimize mechanical stress. When disconnecting, release the connector latch before withdrawing to prevent port damage.

Recommendations

Verify device compatibility and port configuration before installation. Use this 1 m DAC for short-distance, rack-level connections where low latency and low power are priorities. Maintain recommended bend radius and secure cable routing to preserve performance over time.
