Cable de conexión directa Digitus DN-81325 40G QSFP+ a 4x SFP+ 5 m

The DN-81325 Breakout DAC cable QSFP+ to 4x SFP+ provides direct-attach connectivity for 40G Ethernet links and supports interoperability with four independent 10G Ethernet channels. Designed for use in datacenter environments, the cable offers up to 5 m transmission length and operates from 0 ℃ to 70 ℃ on a single +3.3 V power supply. It complies with SFF-8436, SFF-8431, SFF-8432 and SFF-8472 standards to ensure compatibility with compatible switches, servers and NAS systems.

Advantages

The DN-81325 Breakout DAC delivers high channel density and reliable signal integrity for short-reach connections in high-performance computing, core switch and storage deployments. It enables 40G to 4x10G Ethernet interoperability while requiring no optical transceivers, simplifying installation and lowering latency and power compared with active modules.
