BLUELAN BlueOptics SC253501K2M30-BL InfiniBand-kaapeli 2 m QSFP - 4x SFP+ musta

The BLUELAN BlueOptics SC253501K2M30-BL is a Direct Attach Copper (DAC) breakout cable that delivers a combined 40 Gbps data rate by splitting a single QSFP connector into four independent 10 Gbps SFP+ links. Its passive copper design ensures low latency and zero power consumption, making it ideal for dense data center and high-performance computing environments.

Advantages

This cable offers a cost-effective alternative to optical transceivers for short-reach interconnects. The 30 AWG copper conductors provide reliable signal integrity, while the black PVC jacket protects against physical stress. The breakout configuration enables flexible connectivity between 40G QSFP ports and multiple 10G SFP+ devices.

Suitable for

• Connecting 40G QSFP switches to 10G SFP+ servers or storage
• High-density data center top-of-rack deployments
• InfiniBand QDR/FDR and Ethernet 40GBASE-CR4 applications
• High-performance computing clusters requiring low-latency links

Key specifications

• Connector A: QSFP (Quad Small Form-factor Pluggable)
