Alcatel-Lucent 100GBase Direct Attach Cable QSFP28 to QSFP28 5m

100 Gigabit Ethernet over passive copper twinax, 5 meters, QSFP28 to QSFP28.

Overview

The Alcatel-Lucent QSFP-100G-C5M is a 5-meter direct attach cable (DAC) for 100GbE links. It uses passive copper twinax with QSFP28 connectors on both ends, compliant with IEEE 802.3bj (100GBASE-CR4) and SFF-8665. The cable is hot-swappable and consumes less than 0.5W per end.

What stands out

• 100Gbps data rate for high-density data center interconnects
• Passive design: no power required for signal conditioning, ultra-low latency
• 26 AWG twinax construction with PVC jacket for durability
• Hot-swappable QSFP28 connectors for easy installation and maintenance
• Operating temperature range 0°C to 70°C
