Broadbe BCC-DAC-100G-0.5M 100G Direct Attach Cable 0.5m

The Broadbe BCC-DAC-100G-0.5M is a high-performance 100G Direct Attach Cable (DAC) designed for rapid and reliable data transmission over short distances. Measuring 0.5 meters in length, this copper interconnect provides a seamless link between high-speed networking hardware, such as switches, servers, and storage arrays. By utilizing a passive twinax design, it offers a cost-effective and energy-efficient alternative to optical transceivers for intra-rack connectivity, ensuring minimal latency and consistent signal integrity in demanding data center environments.

Advantages

This Direct Attach Cable offers significant benefits for high-bandwidth networking by eliminating the need for separate optical modules, which reduces both power consumption and overall heat generation. Its robust construction ensures reliable performance in high-density environments, while the short 0.5-meter length is optimized to minimize signal degradation and cable clutter within server racks. The plug-and-play nature of the cable simplifies installation, allowing for quick deployment and maintenance without the complexity of fiber optic cabling.

Suitable for

• Connecting top-of-rack switches to servers
• Interconnecting storage area network equipment
• High-speed data center intra-rack links
• Low-latency cluster computing environments

When it may not be suitable

This cable is not intended for long-distance connections, as its passive copper design is strictly limited to short-range applications within a single rack or adjacent cabinets. It is also not compatible with equipment requiring optical fiber interfaces unless appropriate conversion hardware is present.

Key specifications

• Data transfer rate: 100 Gbps
• Cable length: 0.5 meters
• Connector type: QSFP28
• Cable type: Passive Copper Twinax
• Application: Short-range high-speed networking

How to use

To use the Broadbe 100G DAC, simply insert the QSFP28 connectors into the corresponding ports on your networking devices until they click into place. Ensure that the equipment is powered off or that the ports are configured to support 100G DAC connections before installation. The cable does not require external power or complex configuration, making it ready for immediate use once connected.

What to consider before purchase

• Verify that your network hardware supports 100G QSFP28 interfaces
• Ensure the 0.5-meter length is sufficient for your specific rack layout
• Check compatibility with your existing switch or server vendor requirements

Usage recommendations

For optimal performance, avoid bending the cable beyond its minimum bend radius to prevent internal damage. Ensure that the connectors are kept clean and free of dust before insertion into high-speed ports.
