BLUELAN QSFP-4X10G-C2M-BL cavo breakout direct attach passivo compatibile Alcatel-Lucent 40G QSFP a 4x10G SFP+, 2m

Deliver 40 Gbps of aggregate bandwidth across four 10 Gbps lanes with this passive QSFP to 4x SFP+ direct attach breakout cable. Designed for high-density data center interconnects, it connects a 40GBASE-CR4 QSFP port directly to four 10GBASE-CR SFP+ ports without optical modules.

Overview

The BLUELAN QSFP-4X10G-C2M-BL is a 2-meter passive copper twinax breakout cable compatible with Alcatel-Lucent equipment. It features a QSFP connector on one end and four SFP+ connectors on the other, using AWG30 wire for flexible routing. Passive design means negligible power consumption and no additional electronics, making it a cost-effective solution for short-reach, high-speed links.

What stands out

• Aggregate data rate of 40 Gbps (4 × 10 Gbps)
• Passive copper twinax cable – no power required
• 2-meter length with AWG30 wire gauge for easy cable management
• Hot-pluggable QSFP and SFP+ connectors
• Compatible with Alcatel-Lucent OEM part number QSFP-4X10G-C2M
