Overview
- The Ubiquiti QSFP28 Direct Attach Cable is purpose-built for modern high-speed network environments. Each cable supports data rates up to 100 Gbps, making it ideal for connecting switches, routers, and servers in demanding data centre and enterprise settings.
Designed for short-reach, low-latency connections, the 0.5m length is optimally suited for switch-to-switch or switch-to-server communications within equipment racks. The cable's compatibility with both QSFP28 and QSFP+ interfaces provides flexibility across generations of network hardware.
This 10-pack bundle offers cost-effective provisioning for organisations deploying or upgrading multi-switch environments. Direct attach cables eliminate the need for separate transceivers, reducing power consumption, heat generation, and overall system complexity whilst delivering the reliable, high-performance connectivity that modern networks demand.

FAQs
What is the difference between QSFP28 and QSFP+?
QSFP28 is the newer standard supporting up to 100 Gbps, whilst QSFP+ supports up to 40 Gbps. This cable is backward compatible with QSFP+ interfaces, allowing use in either environment.
Can these cables be used for long-distance connections?
No. Direct attach cables are designed for short-reach connections (typically up to 10 metres). For longer distances, optical transceiver modules and fibre optic cables are required.
Are these cables passive or active?
These are passive direct attach cables, meaning they do not require external power or active electronics. They are suitable for connections up to 0.5m without signal degradation.
What devices are compatible with QSFP28 ports?
QSFP28 ports are found on high-performance network switches, routers, and servers. Compatibility depends on your specific hardware model. Consult your equipment's documentation to confirm QSFP28 support.
Why buy in a 10-pack?
The 10-pack provides cost savings compared to purchasing individual cables and ensures consistent inventory for multi-switch deployments or future upgrades.
What warranty coverage is included?
These cables come with a 12-month manufacturer warranty covering defects in materials and workmanship.
Can direct attach cables be replaced with optical modules?
Yes. If you need longer distances, you can replace these passive cables with active optical modules and appropriate transceiver types. However, direct attach cables are more cost-effective and power-efficient for short connections.
