## Long description

SFP28 Twinax DAC Cable CBO SFP28-DAC-5M-NA-BL is a 5 meter direct-attach copper cable with SFP28 male connectors on both ends, designed for 25 Gbit/s short-range connections. The cable provides a cost-effective alternative to optical transceivers for links inside racks or between adjacent racks, offering low latency and reduced power consumption. It is intended for use in data centre environments where reliable, high-speed, low-power connectivity is required between switches, network interface cards and servers.
Advantages
This SFP28 Twinax DAC cable delivers native 25 Gbit/s data throughput with minimal signal loss over its 5 m length and is optimized for short-reach links. Its direct-attach design eliminates the need for separate transceivers, reducing both component count and operating power. The cable’s male-to-male SFP28 connectors ensure simple plug-and-play installation and compatibility with equipment that supports SFP28 direct-attach copper modules. The copper construction provides stable latency performance important for high-performance computing and storage networking.
Suitable for
 Rack-to-rack links in data centres and server rooms
 Direct connections between switches and 25 Gbit/s NICs
 Short-range uplinks and stacking within equipment cabinets
 High-performance computing clusters and storage arrays requiring low-latency interconnects
Key specifications
 Interface: SFP28 male to SFP28 male
 Maximum data rate: 25 Gbit/s
 Length: 5 metres
 Cable type: Twinax direct-attach copper
 Use case: Short-reach, rack-level and intra-rack connectivity
 Latency: low, suitable for latency-sensitive applications
 Power: lower power consumption compared with optical transceivers
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, NIC or server until the latch engages. Verify that both ends are securely seated and that the linked interfaces are enabled in the device management software. Monitor link status and data rates via your network equipment interface to confirm the 25 Gbit/s connection. For best results, use the cable for direct, short-range connections within the same rack or between adjacent racks and avoid routing that subjects the cable to tight bends or mechanical stress.
Usage recommendations
Handle the cable by the connector housings when plugging or unplugging. Maintain minimum bend radius specified by the manufacturer and avoid kinks. Ensure equipment firmware supports SFP28 passive DAC modules and verify compatibility with the specific switch or server vendor if required.
