Direct Attach Cable CBO DAC-QSFP28-100G-5M-BL 5 m QSFP28 male 100 Gbit/s

BlueOptics Direct Attach Cable CBO DAC-QSFP28-100G-5M-BL is a 5‑metre passive copper cable with QSFP28 male connectors that supports 100 Gbit/s links. Engineered for short‑reach interconnects, this DAC delivers a low‑latency, energy‑efficient connection ideal for top‑of‑rack, aggregation and server-to-switch cabling in modern data centre environments. The cable is designed to provide stable, high‑throughput performance while simplifying installation and reducing the need for transceivers.

Advantages

The DAC offers a compact, single‑cable solution that eliminates separate optics and reduces power consumption compared with active modules. Its QSFP28 male interfaces ensure compatibility with equipment supporting direct‑attach copper connections at 100 Gbit/s, while the 5 m length covers common short‑reach topologies without excess slack. The passive copper construction provides predictable latency and consistent signal integrity for high‑performance networking.

Key specifications

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your switches, servers or network appliances until the latch engages. Ensure ports are powered down or follow hot‑plug procedures recommended by the equipment manufacturer if installing into active systems. Verify link status via device LEDs or management interface and confirm negotiated 100 Gbit/s operation. Route the cable to avoid sharp bends and secure it to prevent strain on the connectors.

Recommendations

Choose this 5 m QSFP28 DAC for short‑reach, high‑bandwidth links where power efficiency and low latency are priorities. Confirm host equipment supports passive QSFP28 direct attach copper and follow vendor guidelines for port compatibility and hot‑swap handling.
