BlueLAN X4DACBL2-BL Cable Direct Attach Breakout pasivo 40GBASE-CR4 QSFP a 4x10GBASE-CR SFP+ compatible con Intel, 2 m, AWG30

This BlueLAN breakout cable is a direct replacement for the Intel X4DACBL2, converting a single 40GbE QSFP port into four independent 10GbE SFP+ links. Unlike active optical cables, it uses passive copper conductors to keep power draw at zero and latency at the physical minimum, which matters in dense rack environments where every watt and nanosecond counts.

Highlights

• Passive copper design – no power consumption, no signal regeneration
• QSFP to 4x SFP+ breakout for flexible 40G-to-10G connectivity
• 2-meter length with AWG30 wire gauge for short-reach, high-density cabling
• Hot-swappable connectors for uninterrupted maintenance
• 100-ohm impedance for reliable signal integrity

In daily use

Deploy this cable between a 40GBASE-CR4 switch port and four 10GBASE-CR servers or storage nodes. The breakout design eliminates the need for separate transceivers and patch panels, reducing both cost and points of failure. The 2-meter length is ideal for top-of-rack or adjacent-rack connections, while the passive construction ensures zero added heat in the rack.
