## Summary description

Passive SFP28 DAC copper cable by CBO, model SFP28-DAC-0.5M, length 0.5 m. Designed for direct-attach connectivity between SFP28 ports for 25GbE links, this fixed short cable provides low-latency, energy-efficient connections without transceivers. Suitable for switches, servers and network appliances in data centers and rack environments where short-distance high-speed links are required.

## Long description

Passive SFP28 DAC copper cable CBO SFP28-DAC-0.5M 0.5 m is a fixed direct-attach cable designed for short-distance 25GbE links. Manufactured for use with SFP28 ports, this copper twinax assembly provides a low-latency, power-efficient connection between compatible switches, servers and network appliances without the need for separate optical transceivers. Its half-meter length fits typical rack and data centre topologies where compact, reliable high-speed point-to-point links are required.
Advantages
The passive design reduces power consumption and heat compared with active modules and optics, while delivering stable 25Gb/s signalling for latency-sensitive applications. A fixed cable form factor simplifies installation and inventory management by eliminating separate pluggable transceivers and fibre patch cords. The short 0.5 m length minimises signal attenuation and crosstalk in dense rack environments and helps maintain predictable link performance.
Suitable for
 Direct connections between SFP28 ports on switches and top-of-rack devices
 Short links between servers and storage appliances in racks
 High-density patching in data centres and lab environments
 Cost- and energy-conscious deployments requiring 25GbE point-to-point links
Key specifications
 Interface type: SFP28 to SFP28 direct-attach copper
 Data rate: 25 Gigabit Ethernet (25Gb/s)
 Cable type: Passive twinax copper
 Length: 0.5 m
 Form factor: Fixed DAC assembly with SFP28 connectors
 Typical application: Short-reach, point-to-point connections in racks and enclosures
How to use
Install the cable by firmly inserting each SFP28 connector into the corresponding port on your network devices until the latch engages. Verify link negotiation and speed settings on both ends through device management interfaces. As a passive copper assembly, no external power or configuration is required for the cable itself; only ensure the connected equipment supports SFP28 passive DAC modules and 25GbE operation. For replacement or relocation, disengage the latches and remove the cable carefully to avoid stressing adjacent ports or cables.
Usage recommendations
Place the 0.5 m DAC where short, direct connections are required to preserve signal integrity. Avoid sharp bends and kinks; maintain manufacturer-recommended bend radii for twinax cables. Use this cable in controlled rack environments and check device compatibility lists when mixing vendors to ensure proper link establishment.
