BlueLAN 20G-DACP-QSFP1SFPDD3M Cable de cobre de conexión directa QSFP a SFP-DD compatible de 20 Gbps, 3 m, Twinax pasivo, 100 ohmios, hot-swappable 20G-DACP-QSFP1SFPDD3M-BL

With a 20 Gbps data rate over a 3-meter passive copper twinax link, this BlueLAN direct attach cable bridges QSFP and SFP-DD ports without the cost or complexity of optical transceivers. It is engineered for server-to-server and data center interconnect applications where low latency and low power consumption are critical.

Overview

The BlueLAN 20G-DACP-QSFP1SFPDD3M is a compatible direct attach cable (DAC) that replaces the original 20G-DACP-QSFP1SFPDD3M part. It features a QSFP connector on one end and an SFP-DD (Small Form-factor Pluggable Double Density) connector on the other, delivering a reliable 20 Gbps link over 3 meters of 100-ohm twinax copper. The passive design draws no additional power, making it an energy-efficient choice for dense rack deployments.

What stands out

• 20 Gbps aggregate bandwidth for high-throughput interconnects
• Passive copper twinax construction—no power draw, minimal heat
• QSFP to SFP-DD connectivity supports mixed-port environments
• Hot-swappable for zero-downtime maintenance
• 100-ohm impedance ensures signal integrity over the full length
• RoHS compliant and built for 0°C to 70°C operating range
