## Summary description

The Digitus QSFP28 100G DAC cable is designed for high-speed data transmission in data centers. With a length of 3 meters and QSFP28 connectors, it ensures reliable connections and optimal performance for 100G networks.

## Long description

The Digitus QSFP28 100G DAC cable (3 m, AWG 26) provides a direct-attach copper connection between QSFP28 ports for short-reach 100 Gigabit Ethernet links. Compliant with 100GBASE-CR4, the cable contains four high-speed copper pairs, each supporting up to 25 Gb/s, and uses QSFP28 to QSFP28 connectors to link switches, storage systems and other high-density networking equipment in data centers and enterprise environments.
Advantages
This 100G QSFP28 DAC cable offers a low-cost, power-efficient solution for short-distance interconnects. The AWG 26 twinax construction ensures reliable signal integrity for 4 × 25 Gb/s lanes while avoiding the need for separate transceivers. Its QSFP28 to QSFP28 form factor simplifies deployment in racks and spine/leaf topologies where direct copper links are appropriate.
Suitable for
 Data center top-of-rack and spine connections
 Enterprise storage system interconnects
 High-performance computing clusters
 Short-reach switch-to-switch links

How to use
Insert each QSFP28 connector into compatible QSFP28 ports on the devices to be connected, ensuring proper alignment and full seating. Use the 3 m DAC to connect adjacent racks or equipment within the same rack where short-reach copper interconnects are supported. Verify link status on connected devices and ensure port settings match the expected 100G operation.
Usage recommendations
For optimal performance, use this AWG 26 QSFP28 DAC for links within the recommended short-reach distance (3 m) and avoid bending the cable beyond the manufacturer’s minimum bend radius. Choose DACs when direct, cost- and power-efficient connections are acceptable and when both ends support QSFP28 direct-attach copper links.
