BlueLAN QSFP-4SFP10G-CU2M-BL cavo breakout Direct Attach passivo compatibile Cisco 40GBASE-CR4 a 4x10GBASE-CR SFP+, 2m, AWG30

This passive direct attach breakout cable provides a high-density 40G to 4x10G interconnect, splitting a single QSFP port into four independent SFP+ links. It delivers an aggregate bandwidth of 40 Gbps over a 2-meter AWG30 copper assembly, enabling flexible top-of-rack connectivity in data centers and high-performance computing environments.

Advantages

The cable is fully compatible with Cisco QSFP-4SFP10G-CU2M and supports hot-swappable installation, allowing quick deployment without network downtime. Its passive design consumes less than 0.1W, reducing power and cooling costs compared to active optical alternatives. The 100-ohm impedance ensures reliable signal integrity across all four 10G channels.
