40G DAC Breakout cable, 1xQSFP+(40G) to 4xSFP+(10G), 1m

The 40Gbps QSFP+ to 4x SFP+ Direct Attach Copper (DAC) Breakout Cable is a high-performance, cost-effective connectivity solution designed for short-range interconnections in data centers and enterprise networking environments. It enables a hybrid connection between a single 40G QSFP+ port on a high-speed switch and four individual 10G SFP+ ports on servers, storage devices, or downstream switches, effectively splitting a single 40Gbps channel into four independent 10Gbps data streams.

Constructed with high-quality twinaxial copper cabling and integrated with permanent, factory-terminated transceiver shells on both ends, this passive breakout cable eliminates the need for separate, expensive optical transceivers and fiber patch cords. It operates over short distances—typically ranging from 1 to 7 meters—delivering ultra-low latency, near-zero power consumption, and reliable signal integrity. Fully compliant with SFF-8436, SFF-8431, and IEEE 802.3ba standards, this product offers an ideal plug-and-play solution for high-density network upgrades, top-of-rack (ToR) deployments, and budget-conscious hardware aggregation.
