BlueLAN Compatível H3C LSWM1QSTK4 Cabo breakout passivo 40GBASE-CR4 QSFP+ para 4x10GBASE-CR SFP+ Direct Attach, 3m, AWG30 LSWM1QSTK4-BL

This BlueLAN direct attach breakout cable delivers a 40Gbps aggregate link by splitting a single QSFP+ port into four 10Gbps SFP+ connections. Its passive twinax design ensures low latency and zero power draw for short-reach data center interconnects.

Advantages

Engineered for H3C LSWM1QSTK4 compatibility, this cable uses AWG30 copper conductors to balance flexibility and signal integrity over 3 meters. Passive construction eliminates active electronics, reducing cost and failure points while maintaining 100 Ohm impedance for reliable 40GBASE-CR4 and 10GBASE-CR signaling.

Suitable for

• Connecting a 40G QSFP+ switch port to four 10G SFP+ server or switch ports
• High-density top-of-rack deployments where cable management is critical
• Data centers requiring hot-swappable, low-latency copper links

Key specifications

• Connector A: QSFP+ (40GBASE-CR4)
• Connector B: 4 x SFP+ (10GBASE-CR)
• Aggregate data rate: 40 Gbps (4 x 10 Gbps)
• Cable length: 3 meters
• Wire gauge: AWG30
• Passive twinax copper cable
• Impedance: 100 Ohm
• Operating temperature: 0°C to 70°C
• Standards: SFF-8436, SFF-8431

Recommendations

Verify that your H3C equipment supports passive DAC breakout cables before deployment. For distances beyond 3 meters, consider active optical cables for reliable signal integrity.
