When rack density is high and cable runs need to stay short, this AddOn Networks passive direct attach cable keeps the path simple. It connects a QSFP28 port to four SFP28 endpoints over 1.5 m, making it a strong fit for compact top-of-rack layouts, adjacent equipment, and breakout configurations where clean cable management matters. The passive copper design avoids the added cost, heat, and power requirements of active optics while maintaining the direct electrical signaling preferred for short-reach 100 GbE links. That makes it a practical option for infrastructure teams that want predictable performance without over-specifying the interconnect. The 4-way breakout format also supports migration and consolidation strategies, letting one 100 GbE port serve four 25 GbE links where the architecture calls for it. Dell compatibility reduces qualification friction in mixed-vendor environments, and TAA compliance helps satisfy regulated purchasing requirements. For teams standardizing on short copper runs, this 1.5 m cable offers a precise fit where longer assemblies would add slack, clutter, and unnecessary handling overhead.
