BLUELAN QSFP-4X10G-C2M-BL Compatible Alcatel-Lucent 40G QSFP to 4x10G SFP+ Passive Direct Attach Breakout Cable, 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.
