Broadbe BCC-DAC-100G-0.3M 100G Direct Attach Cable 0.3m

The Broadbe 100G Direct Attach Cable (DAC) is a high-performance connectivity solution engineered for short-range data center applications. Measuring 0.3 meters in length, this passive copper cable is specifically designed to facilitate high-speed data transmission between network switches, servers, and storage systems located within the same rack or adjacent cabinets. By utilizing a direct copper connection, it offers a cost-effective and energy-efficient alternative to optical transceivers for short-distance links.

Advantages

This 100G DAC provides exceptional signal integrity and minimal latency, which are critical requirements for modern high-performance networking environments. Because it is a passive cable, it consumes zero power, helping to reduce the overall energy footprint of the data center. The robust construction ensures reliable performance and durability, while the short 0.3-meter length minimizes cable clutter, improving airflow and cable management within high-density server racks.

Suitable for

• Connecting top-of-rack switches to servers
• Interconnecting storage arrays within a single rack
• High-speed data center networking
• Low-latency cluster computing environments

When it may not be suitable

This cable is not suitable for long-distance connections, as its passive copper design is limited to short reaches within a rack or between adjacent racks. It cannot be used for inter-row or inter-room connectivity where optical fiber solutions are required to maintain signal strength over longer distances.

Key specifications

• Data rate: 100 Gbps
• Cable length: 0.3 meters
• Connector type: QSFP28
• Cable type: Passive copper
• Application: Short-range interconnects

How to use

To install the cable, ensure that both the network switch and the server or storage device are powered on or prepared for hardware insertion. Align the QSFP28 connector with the port on the networking equipment and push it firmly until the locking mechanism clicks into place. No additional configuration is typically required, as the system will automatically recognize the connection. To remove the cable, pull the release tab on the connector to disengage the lock before gently sliding it out of the port.

What to consider before purchase

• Verify that your networking equipment supports QSFP28 ports
• Ensure the 0.3-meter length is sufficient for your specific rack layout
• Check the compatibility list of your switch or server manufacturer

Usage recommendations

For optimal performance and to prevent damage to the connectors, avoid bending the cable beyond its minimum bend radius. Ensure that the cable is properly routed through cable management arms to prevent strain on the ports.
