BlueLAN QSFP28-100G-CU2M-BL 100G QSFP28 Passive Direct Attach Copper Cable, 2m, 30AWG, Compatible with Huawei

The BlueLAN QSFP28-100G-CU2M-BL is a high-performance 100G QSFP28 passive direct attach copper (DAC) cable designed for data center and enterprise networking applications. It provides a cost-effective, low-power solution for short-range 100GBASE-CR4 connections, compatible with Huawei QSFP28-100G-CU2M interfaces. With a length of 2 meters and 30AWG twinax construction, this cable ensures reliable signal integrity and minimal latency.

Advantages

This DAC cable offers significant advantages over active optical cables and transceivers: lower power consumption (typically less than 0.5W), reduced cost, and simplified cable management. The passive design requires no external power, making it ideal for high-density environments. It supports hot swapping and is fully compliant with IEEE 802.3bj 100GBASE-CR4 standards.

Suitable for

• Data center top-of-rack (ToR) to server connections
• High-performance computing (HPC) clusters
• Enterprise network core and distribution layer links
• Storage area networks (SAN) requiring low latency
