BlueLAN Cabo breakout Direct Attach passivo 40G QSFP+ para 4x10G SFP+, 2 m, AWG30, compatível com Huawei QSFP-4SFP10G-CU2M-HU-BL

High-density 40G Ethernet uplinks often require splitting a single QSFP+ port into four independent 10G SFP+ connections. This BlueLAN passive Direct Attach Breakout (DAC) cable delivers exactly that in a single, ready-to-use assembly: one QSFP+ connector on one end and four SFP+ connectors on the other, eliminating the need for separate transceivers and fibre patch cords.

Who is it for

Network engineers and data centre operators who need to connect a 40GBASE-CR4 switch port to multiple 10GBASE-CR servers, storage nodes or top-of-rack switches over short distances. It is compatible with Huawei equipment, making it a practical choice for Huawei-based infrastructures.

Main features

• Passive copper twinax design: no signal processing, minimal power consumption, and low latency.
• 40GBASE-CR4 QSFP+ to 4x 10GBASE-CR SFP+ breakout configuration.
• 2-meter length with AWG30 wire gauge, ideal for intra-rack and adjacent-rack cabling.
• Hot-swappable connectors for easy installation and maintenance.
• Compliant with IEEE 802.3ba and IEEE 802.3ae standards.
