QSFP-DD Cable Connects High-Density Network Equipment at Speeds Up to 400 Gbps Tripp Lite's N282D-01M-BK provides next-generation performance by combining eight 50 Gb SFP channels into one high-density cable. It's a direct-attach solution ideal for connecting newer switches and other active network devices over short distances in data centers, high-end servers, telco rooms and enterprise wiring closets. Best-in-Class Construction Optimized for Applications That Use Much Bandwidth This passive copper cable integrates a 400G Ethernet-optimized (400 GbE) 38-position "board as connector" design. Zinc die-cast QSFP-DD connectors on both ends offer superior EMI resistance, minimal insertion loss and low crosstalk for top performance. Ergonomic push/pull tabs make the cable easy to install or remove with one hand. Eight-pair wire technology is optimized for bandwidth-intense applications, such as 128G Fibre Channel and EDR 4x InfiniBand. Flexible 30 AWG conductors maintain a smooth high-frequency response. Fully Compliant and Compatible with a Wide Range of Applications The N282D-01M-BK undergoes a rigorous assembly and testing procedure aimed at eliminating unnecessary signal loss. It's fully compliant with the MSA (Multi-Source Agreement) SFF-8665 architecture for guaranteed compatibility with all QSFP-DD ports, as well as RoHS, REACH and IEEE 802.3cd. It is also backward compatible with 40 Gb and 100 Gb networks, so you can future-proof your current application for an eventual upgrade to 400 Gb.
