Use cases include high-speed 100GbE connections in data centers and telecom racks, simplifying installation and reducing power consumption.

## Long description

Passive DAC cable CBO QSFP28 SC282801L0.5M30 is a 0.5 m direct attach copper (DAC) cable designed for QSFP28 ports. The cable provides a fixed-length electrical connection for 100GbE short-reach interconnects between switches, routers and servers without the need for optical transceivers. Its low-latency, low-power design is intended for dense rack-level connections in data centers and telecom equipment racks where short copper links are appropriate.
Advantages
This passive QSFP28 direct attach copper cable offers a simple plug-and-play connection with no separate transceivers required, reducing component count and simplifying installation. The short 0.5 m length minimizes signal attenuation and latency for top-of-rack or adjacent-rack links while avoiding the cost and power consumption associated with optical modules. The cable is compatible with standard QSFP28 ports and provides a stable electrical interface for high-speed 100GbE traffic.
Suitable for
Short-reach 100GbE links between rack-mounted switches and servers
Top-of-rack and adjacent-rack interconnects in data centers
High-density telecom rack patching where optical transceivers are not required
Latency-sensitive applications that benefit from copper direct attach
Key specifications
Connector type: QSFP28 to QSFP28 direct attach copper
Cable type: Passive DAC (direct attach copper)
Length: 0.5 m fixed
Supported link rate: 100 Gigabit Ethernet (100GbE)
Use case: Short-reach, intra-rack and adjacent-rack connections
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the networking devices until the latch engages. Ensure both devices are powered and configured for the required 100GbE link settings. No additional transceivers or fiber patching are required; the cable provides a direct electrical connection. For best results, route the cable to avoid sharp bends and mechanical strain on the connectors.
Usage recommendations
Use the 0.5 m passive DAC cable for short-distance connections inside the same rack or adjacent racks. Verify port compatibility and link configuration on both ends before deployment. Avoid exposing the cable to excessive heat, moisture, or repeated flexing; maintain gentle bend radii and secure the cable to prevent connector strain.
