Cavo DAC CBO QSFP28 SC282801L1M30 1 m — Direct Attach Copper per connessioni QSFP28

The CBO QSFP28 SC282801L1M30 is a 1 m direct attach copper (DAC) cable designed for QSFP28 ports and 100GbE-compatible devices. Intended for short-reach connections in data centers and network racks, this fixed copper assembly provides a low-latency, high-throughput physical link between compatible QSFP28 transceivers and ports. The compact, pre-terminated cable eliminates the need for separate transceivers and supports straightforward rack-to-rack and within-rack interconnects where a reliable wired connection is required.

Advantages

This DAC cable offers predictable electrical performance and low latency compared with optical alternatives at similar distances, with no requirement for additional optical modules. The one-meter length provides a tidy routing option for adjacent equipment in racks, reducing clutter and maintaining signal integrity. The pre-terminated QSFP28 connector ends enable plug-and-play installation, simplifying deployment and minimizing configuration steps.

Suitable for

• Short-reach 100GbE connections between QSFP28-enabled switches
• Switch-to-server interconnects in rack environments
• Within-rack or adjacent-rack uplinks where fixed copper cabling is acceptable

Key specifications

• Connector type: QSFP28 direct attach copper (fixed assembly)
• Cable length: 1 meter
• Data rate compatibility: 100 Gigabit Ethernet (100GbE) signaling
• Application: Short-reach, within-rack and adjacent-rack links
• Latency: Low, electrical copper link characteristics
• Physical characteristics: Pre-terminated, stranded copper conductors with molded connector housings

How to use

Install the DAC cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure compatible QSFP28 ports are powered down or follow hot-plug guidelines from your hardware vendor if connecting live. Route the cable to avoid sharp bends and to maintain the minimum bend radius recommended by the rack vendor. Verify link status and interface configuration in your network equipment once both ends are connected.

Recommendations

Use this 1 m DAC cable for short, direct copper links where 100GbE performance is required and optical transceivers are not necessary. Avoid excessive bending, pulling, or exposure to mechanical stress; store and route the cable inside racks or trays to preserve signal integrity and connector reliability.
