BlueLAN 40G-QSFP-4SFP-PC-0201-BL Compatible Brocade Passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ Direct Attach Breakout Cable, 2m, 30 AWG

Aggregate 40 Gbps throughput meets versatile 4x 10 Gbps breakout in this 2-meter passive Direct Attach Copper cable. The BlueLAN 40G-QSFP-4SFP-PC-0201-BL connects a single QSFP port to four independent SFP+ ports, delivering 40GBASE-CR4 and 10GBASE-CR connectivity without active electronics.

Overview

Built for Brocade environments, this passive DAC breakout cable uses 30 AWG copper conductors to link a 40G QSFP connector to four 10G SFP+ connectors. It is hot-pluggable and consumes minimal power, making it ideal for dense data center interconnects and network switching topologies.

What stands out

• Aggregate data rate: 40 Gbps (4 lanes x 10 Gbps)
• Passive design – no power draw, low latency
• Compatible with Brocade switches and adapters
• 2-meter length for flexible rack and row connections
• 30 AWG copper construction for signal integrity

Technical details

• Connector A: QSFP (Quad Small Form-factor Pluggable)
• Connector B: 4x SFP+ (Small Form-factor Pluggable Plus)
• Ethernet standards: 40GBASE-CR4, 10GBASE-CR
• Hot-pluggable: Yes
• Power consumption: Low (passive)
• Application: Data center interconnect, network switching

Our verdict

A reliable, low-cost way to break out a 40G QSFP port into four 10G SFP+ links for Brocade equipment, with no active components to fail.
