## Summary description

CBO DAC-QSFP-100G-5M-BL is a 5 meter direct attach copper (DAC) cable with QSFP28 male connectors supporting 100 Gbit/s links. Designed for short-range high-speed connections between switches, routers or servers, it offers low-latency, power-efficient interconnects for data centers and network racks where fiber transceivers are unnecessary.

## Long description

CBO DAC-QSFP-100G-5M-BL is a 5 meter direct attach copper (DAC) cable with QSFP28 male connectors designed for short-range 100 Gbit/s links. The cable provides a low-latency, power-efficient physical connection between switches, routers and servers in data centers and network racks where fiber optics or active transceivers are unnecessary. Its fixed-length copper assembly simplifies rack cabling and supports high-bandwidth interconnects for top-of-rack, aggregation and leaf-spine network topologies.
Advantages
The direct attach copper design delivers low latency and reduced power consumption compared with optical transceivers and active modules at short distances. QSFP28 male connectors ensure compatibility with 100G-capable QSFP28 ports and provide a reliable mechanical mating. The 5 m length offers flexibility for common rack-to-rack and chassis-to-chassis connections while keeping signal integrity suitable for 100 Gbit/s operation. As a passive solution, the cable requires no additional power or SFP modules and simplifies inventory management.
Suitable for
 High-speed links between top-of-rack switches and aggregation switches
 Interconnecting routers and 100G-capable server NICs within the same rack or adjacent racks
 Leaf-spine and spine-leaf architectures in data center networks
 Short-range connections where optical transceivers are not required
Key specifications
 Connector type: QSFP28 male to QSFP28 male
 Data rate: 100 Gbit/s
 Length: 5 meters
 Cable medium: direct attach copper (passive copper assembly)
 Typical use: short-range, high-bandwidth interconnects in rack environments
How to use
Insert each QSFP28 connector into compatible 100G QSFP28 ports on network equipment until the latch engages. Ensure both ends are seated properly and that port LEDs or management interfaces indicate a valid link. Avoid sharp bends and maintain the cable bend radius recommended by equipment vendors to preserve signal integrity. For installation, route the cable along existing cable management paths to prevent strain and interference with airflow in racks.
Usage recommendations
Verify compatibility with the target devices' QSFP28 ports and port firmware; passive DAC compatibility can depend on hardware and firmware combinations. Use the 5 m length for short interconnects within or between adjacent racks, and keep the cable away from high-power electrical sources to minimize potential interference. For long-term reliability, inspect connectors for damage before insertion and replace the cable if the connector or conductors show wear.
