## Summary description

CBO CAB-Q-Q-100G-1M-BL is a 1 m QSFP28 to QSFP28 direct-attach copper (DAC) cable that supports 100 Gbit/s links. With male QSFP28 connectors on both ends and a blue jacket, it is intended for short-reach, high-speed interconnects between compatible switches, routers, NICs or servers. It provides a compact, low-latency, cost-effective cabling option for data center top-of-rack and equipment-to-equipment connections.

## Long description

CBO QSFP28 to QSFP28 100 Gbit/s Direct-Attach Copper Cable 1 m, male–male, blue is a 1 metre direct-attach copper (DAC) assembly designed to support 100 Gbit/s links between QSFP28 ports. The cable features male QSFP28 connectors on both ends and a blue outer jacket, offering a low-latency, power-efficient and compact physical connection for short-reach interconnects in data center and enterprise network environments.
Advantages
This QSFP28 to QSFP28 DAC provides a cost-effective alternative to active optical modules for short-distance 100 Gbit/s connections. Because it uses passive copper wiring for a one-metre run, the cable yields low latency and reduced power consumption compared with active transceivers and fiber assemblies. The integrated male QSFP28 connectors ensure simple plug-and-play deployment and a small form factor that suits high-density top-of-rack and equipment-to-equipment cabling.
Suitable for
 Short-reach 100 Gbit/s links between switches and routers in racks
 Direct 100G connections between servers and network interface cards (NICs)
 Top-of-rack aggregation and spine-leaf interconnects within the same rack or adjacent racks
 High-density data center deployments requiring compact, low-latency cabling
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Rated data rate: 100 Gbit/s
 Cable length: 1 metre
 Cable type: Direct-attach copper (DAC), passive
 Jacket colour: blue
 Typical use: short-reach interconnects for data centre equipment
How to use
Insert each QSFP28 male connector into compatible QSFP28 ports on the devices to be connected, ensuring correct alignment with the port guide. Secure the connectors until they click into place and verify link status using device indicators or management software. For first-time use, confirm that connected equipment supports passive DAC cables at 100 Gbit/s and configure link parameters if required. To remove the cable, release the latch mechanism on each connector and pull straight out without twisting to avoid damage.
Usage recommendations
Use the cable for short-distance, high-throughput links within racks or between adjacent racks; avoid running this passive DAC beyond the intended short-reach distance and keep bends above the manufacturer’s recommended minimum bend radius. Store and handle the cable to prevent sharp kinks and protect connector ends from dust when not in use.
