## Summary description

CBO QSFP28 QSFP-100G-CU2M-HU-BL is a 2 m direct attach copper (DAC) cable supporting 100 Gbit/s links for short-reach high-speed networking. Designed for QSFP28 ports, it provides low-latency, energy-efficient connectivity between switches, routers or NICs in data centers and server racks. Ideal for cost-effective 100G interconnects and aggregation.

## Long description

CBO QSFP28 Direct Attach Copper Cable QSFP-100G-CU2M-HU-BL 2 m 100 Gbit/s is a 2-metre passive direct attach copper (DAC) cable engineered for short-reach 100 Gbit/s connections in data center and high-density network environments. The cable uses a QSFP28 form factor on both ends to link compatible QSFP28 ports on switches, routers and network interface cards (NICs). It is intended for reliable, low-latency, and energy-efficient connectivity where fibre transceivers are not required.
Advantages
This QSFP28 DAC cable offers a cost-effective solution for 100 Gbit/s links with lower power consumption compared to active optical solutions. Its passive copper design delivers minimal latency and predictable electrical performance for short distances, simplifying port-to-port connections in rack-to-rack or within-rack deployments. The fixed 2 m length reduces clutter and improves cable management in dense installations.
Suitable for
 Short-reach 100 Gbit/s connections between switches and routers in data centers
 Server to top-of-rack switch interconnects
 Aggregation links and spine-leaf architectures with QSFP28 ports
 High-density rack installations requiring low-latency interconnects
Key specifications
 Form factor: QSFP28 to QSFP28 direct attach copper
 Data rate: up to 100 Gbit/s
 Length: 2 metres
 Cable type: passive copper DAC
 Typical use: short-reach, rack-to-rack or within-rack connections
How to use
Insert each QSFP28 connector into a compatible QSFP28 port until the latch engages. Ensure both network devices are powered and configured for 100 Gbit/s operation and that port presets (speed/auto-negotiation) match. For best results, route the 2 m cable to avoid sharp bends and keep it clear of heat sources or high-interference equipment. Verify link status through the network device management interface after installation.
Usage recommendations
Use this 2 m QSFP28 DAC cable for short-distance, high-bandwidth links where low latency and power efficiency are priorities. Confirm QSFP28 port compatibility with the device vendor and check firmware settings if the link does not come up. Avoid exceeding bend radius and handle connectors by the housing to prevent contact damage.
