QNAP CAB-DAC15M-Q28B4 1.5 m QSFP28 to 4x SFP28 DAC

Turn one 100 GbE uplink into four 25 GbE connections with QNAP’s QSFP28 breakout twinaxial direct attach cable. This 1.5 m cable is designed for short-reach infrastructure where a single high-speed port must feed multiple SFP28 endpoints without adding optical modules, patch panels, or unnecessary complexity. For data center teams building dense leaf-spine or aggregation layers, breakout cabling is often the cleanest way to match port speed to device requirements. This cable supports that design by converting a QSFP28 interface into four SFP28 links, helping preserve switch port value while keeping the physical layer simple and direct. At 1.5 m, it is suited to within-rack and adjacent-rack layouts where cable length must be controlled and routing must stay orderly. The twinaxial copper construction is a practical fit for short-distance 100 GbE-to-25 GbE fan-out, especially when the goal is to reduce transceiver count and keep the rack easier to service.
