BlueOptics Supermicro CBL-NTWK-0944-SS28C20M Compatible BlueLAN 25GBASE-CR Passive SFP28 Direct Attach Copper Cable, 2m, AWG30

The BlueOptics BlueLAN passive SFP28 Direct Attach Copper (DAC) cable is a high-performance, cost-effective solution for 25 Gigabit Ethernet connections in data centers and enterprise networks. Designed as a compatible alternative to the Supermicro CBL-NTWK-0944-SS28C20M, this cable delivers reliable, low-latency connectivity for server-to-switch and rack-to-rack applications.

Advantages

This passive DAC cable offers the lowest power consumption (<0.1W) and zero latency compared to active optical cables, making it ideal for short-range, high-density deployments. The AWG30 gauge ensures flexibility for easy cable management, while the SFP28 connectors provide hot-swappable, secure connections. Fully compliant with SFF-8402, SFF-8431, and SFF-8472 standards, it guarantees interoperability with Supermicro and other compatible 25GBASE-CR equipment.

Suitable for

• Data center interconnects (top-of-rack to server)
• 25 Gigabit Ethernet networks
• Supermicro and compatible SFP28 switches, servers, and storage
• Short-distance, high-bandwidth links (up to 2 meters)
