Lenovo 1.5m Passive 400G QSFP112 DAC 4X97B00141 | QSFP112, 400G, Enterprise

When a 1 m cable is too short but optics are still unnecessary, this 1.5 m passive QSFP112 DAC fills the gap. Lenovo’s 1.5m Passive 400G QSFP112 DAC is built for short-distance 400G connectivity in dense infrastructure where simplicity, cost control, and predictable performance matter. Passive direct-attach copper keeps the link straightforward and avoids the added power and component overhead of optical transceivers. The extra half meter gives teams more placement flexibility for top-of-rack, end-of-row, and adjacent-cabinet connections while staying within the practical range for passive copper. It is a strong fit for 400G switch fabrics, server uplinks, and short interconnects where the goal is to preserve bandwidth without introducing unnecessary complexity. For organizations standardizing on 400G, this cable helps maintain a consistent cabling strategy across close-proximity equipment. It is a precise choice for environments that want the economics of DAC with just enough reach to make rack layouts easier to manage.
