BlueOptics E100G-QSFP-QSFP-P-0301 Compatible BlueLAN DAC QSFP28 3m Passive Copper Twinax Cable

The BlueOptics E100G-QSFP-QSFP-P-0301 is a high-performance, passive Direct Attach Copper (DAC) cable designed for 100 Gigabit Ethernet (100GBASE-CR4) applications. This BlueLAN compatible QSFP28 to QSFP28 cable provides a cost-effective, low-power solution for short-range interconnects within data centers, enterprise networks, and high-performance computing environments. With a length of 3 meters, it offers reliable, high-speed connectivity for top-of-rack to server or switch connections.

Advantages

This DAC cable eliminates the need for separate transceivers and fiber optic cabling, reducing overall system cost and power consumption. Its passive design ensures near-zero power draw (<0.5W) and minimal latency, making it ideal for high-density, energy-efficient deployments. The cable is hot-pluggable and MSA compliant, guaranteeing interoperability with standard QSFP28 ports from major vendors.

Suitable for

• Data center top-of-rack (ToR) to server connections
• Enterprise network core-to-edge links
• High-performance computing (HPC) clusters
• Storage area networks (SAN) requiring 100G connectivity
