BlueLAN LSWM1QSTK3-BL 40GBASE-CR4 QSFP - 4x10GBASE-CR SFP+ passiivinen Direct Attach -haarakaapeli, 1 m, AWG30

Deliver 40 Gbps of aggregate bandwidth with this 1-meter passive QSFP to 4x SFP+ breakout cable. It splits a single 40GBASE-CR4 QSFP port into four independent 10GBASE-CR SFP+ links, making it a compact and power-efficient choice for dense server-to-switch and switch-to-switch interconnects.

Overview

The BlueLAN LSWM1QSTK3-BL is a direct attach copper cable engineered for H3C LSWM1QSTK3 compatible environments. The QSFP connector plugs into a 40G port, while the four SFP+ ends connect to 10G devices. Passive construction means no signal amplification, resulting in ultra-low latency and minimal power draw. AWG30 wire keeps the cable thin and flexible for easy routing in high-density racks.

What stands out

• Aggregate data rate: 40 Gbps (4 x 10 Gbps)
• Passive copper design for ultra-low latency and low power consumption
• Hot-pluggable QSFP and SFP+ connectors for easy installation
• 1-meter length, AWG30 gauge for flexible cable management

Technical details

• Connector A: QSFP (40GBASE-CR4)
• Connector B: 4 x SFP+ (10GBASE-CR)
• Cable type: Direct Attach Cable (DAC), breakout configuration
• Cable length: 1 m (3.3 ft)
• Wire gauge: AWG30
• Cable material: Copper
• Compatibility: H3C LSWM1QSTK3

Our verdict

A reliable, energy-efficient way to fan out a 40G QSFP port into four 10G SFP+ connections. Perfect for short-reach, high-density data center links.
