## Long description

Direct attach copper (DAC) cable CBO QSFP28-DAC-5M is a 5-meter twinax cable compatible with Chelsio QSFP28 ports. Designed for short-range 100GbE connections between switches, routers and servers, it enables direct 100 Gigabit Ethernet links without separate optical transceivers. The passive/active twinax construction provides a compact, low-power physical link for rack-to-rack and top-of-rack deployments in data center environments.
Advantages
The 5 m length balances reach and signal integrity for common data center layouts while avoiding unnecessary excess cable. Compatibility with QSFP28 ports ensures straightforward plug-and-play installation with equipment that supports QSFP28 interfaces. Using a DAC cable reduces latency and power consumption compared with transceiver-plus-optical-fiber solutions and delivers cost-effective high-bandwidth connectivity for short distances.
Suitable for
 100 Gigabit Ethernet rack-to-rack links in data centers
 High-speed server uplinks to QSFP28-capable switches
 Short-reach interconnects between routers and switches
Key specifications
 Connector type: QSFP28 to QSFP28 compatible with Chelsio ports
 Cable type: twinax copper (DAC)
 Nominal data rate: 100GbE (100 Gigabit Ethernet)
 Length: 5 meters
 Typical deployment: short-range, within-rack or rack-to-rack
 Latency: low, direct electrical connection without optical conversion
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your switches, routers or servers until the latch clicks. Ensure both devices support QSFP28 interfaces and 100GbE operation. Route the cable to avoid sharp bends and maintain the recommended bend radius to preserve signal integrity. No additional transceivers, modules or configuration are required on most systems beyond verifying link speed and port settings in the network equipment.
Usage recommendations
For reliable operation, verify compatibility with the equipment vendor's QSFP28 port support list, avoid excessive cable tension, and keep cable runs within the specified 5 m length for optimal performance. Use proper cable management to maintain airflow and simplify maintenance in rack environments.
