## Long description

CBO DAC cable QSFP28 QSFP-100G-D-CAB-5M-BL is a 5-meter direct-attach copper (DAC) cable engineered to provide short-reach 100G connectivity between QSFP28 ports. Designed for use in data centers and server rooms, the cable features QSFP28 connectors on both ends and a durable blue jacket for easy identification. This direct-attach solution delivers electrical interconnect capability without transceivers, simplifying rack-to-rack and switch-to-switch connections where distances are within the cable's reach.
Advantages
The cable offers low latency and stable signal integrity for 100G links while reducing power consumption compared with optics-based solutions. Its fixed-length, plug-and-play design eliminates the need for separate transceiver modules and reduces component count in dense deployments. The blue outer jacket improves visual management in cable bundles and the construction is optimized for reliable mating cycles and consistent performance in short-distance interconnects.
Suitable for
 Short-reach interconnects between switches and routers within a data center rack or adjacent racks
 Direct connections between high-speed network interface cards (NICs) and switch ports
 High-density top-of-rack and leaf-spine deployments requiring 100G electrical links
 Temporary or permanent point-to-point links where optical transceivers are not required
Key specifications
 Connector type: QSFP28 to QSFP28 electrical direct-attach
 Data rate: 100 Gigabits per second
 Length: 5 meters
 Cable type: Direct-attach copper (DAC)
 Jacket color: Blue
 Application: Short-reach rack-to-rack and intra-rack interconnects
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port until the cable latches securely. Ensure both endpoints are powered down or follow hot-plug guidelines of the equipment manufacturer if performing live insertion. Verify link status through the switch or NIC management interface and confirm the negotiated 100G rate. Route the cable to avoid sharp bends and mechanical strain; maintain the recommended bend radius indicated by the equipment vendor. For troubleshooting, reseat the connectors and check port LEDs or management console messages for link diagnostics.
Usage recommendations
Use this 5 m DAC cable for short-distance electrical 100G links inside racks or between adjacent racks. Avoid exceeding the specified length for reliable performance, keep the cable away from high-heat sources, and follow your equipment manufacturer's guidelines for hot-plugging and port compatibility.
