CBO DAC-kabel BlueLAN QSFP28 SC282801L2M30 2M — Direct Attach koper QSFP28, 2 m

CBO BlueLAN QSFP28 SC282801L2M30 is a 2‑meter direct‑attach copper (DAC) cable designed for QSFP28 ports. The cable provides a short‑reach physical connection for 100 Gigabit Ethernet and compatible QSFP28 equipment without the need for separate optical transceivers. It is intended for use in dense networking environments such as data centre racks, switch-to-switch links and server uplinks, offering a compact, low-latency interconnect option.

Advantages

The direct‑attach copper design delivers low latency and minimal power consumption compared with active optical solutions. As a fixed copper assembly, the cable reduces component count by integrating connectors and cable into a single unit that is simple to install. Its 2 m length is suitable for short inter-rack or in-rack connections, enabling cost-effective connectivity and simplified cabling management in high-density network deployments.

Suitable for

• 100GbE connections between switches in data centres
• Server uplinks to QSFP28 capable network cards
• Short-reach links inside racks and between adjacent racks
• High-density top-of-rack switch deployments

Key specifications

• Connector type: QSFP28 to QSFP28 direct-attach copper
• Cable length: 2 m
• Supported speed: 100 Gigabit Ethernet (QSFP28)
• Form factor: Passive copper assembly for short-reach links
• Typical use environment: Data centre, server room, switching cabinets

How to use

Insert each QSFP28 end into the corresponding QSFP28 port on your devices until the connector latches. Ensure both devices support direct‑attach copper connections at the intended speed and that firmware or driver settings allow 100GbE operation. Route the cable to avoid tight bends and physical strain; maintain service loop where necessary for airflow and maintenance access. No separate transceivers or additional power is required for passive DAC operation.

Recommendations

Use this 2 m DAC for short interconnects inside racks or between adjacent racks. Verify compatibility with your switch or server vendor for QSFP28 passive cables and avoid exceeding the recommended bend radius to maintain signal integrity and mechanical reliability.
