BlueLAN cable Direct-Attach-Breakout pasivo 40G QSFP a 4x10G SFP+, 2m, AWG30, compatible con IBM (BN-QS-SP-CBL-2M-IB-BL)

High-density 40GbE deployments often force a choice between expensive active optics and bulky fibre trunks. This BlueLAN breakout cable solves that by splitting a single 40G QSFP port into four independent 10G SFP+ links over one slim, passive copper assembly.

Who is it for

Network engineers and data centre operators connecting 40G switches to 10G servers, storage or top-of-rack devices. It is ideal for short-reach, high-port-count environments where power and latency must stay low.

Main features

• Passive direct attach copper cable – zero power draw and near-zero latency.
• QSFP (SFF-8436) to 4x SFP+ (SFF-8431) breakout configuration.
• Aggregate 40 Gbps (4x 10 Gbps per lane).
• 2 metre length, AWG30 wire gauge, 100 Ohm impedance.
• Compatible with IBM equipment requiring BN-QS-SP-CBL-2M-IB.

Tips

Verify the switch port supports breakout mode before connecting. Keep bend radius above the manufacturer's recommendation to maintain signal integrity.
