The N282-20N-28-BK QSFP28 to QSFP28 100GbE Passive DAC Copper InfiniBand Cable provides next-generation performance by combining four 28 Gbps SFP channels into one high-density cable. It’s ideal for connecting active network equipment in data centers, high-end servers and enterprise wiring closets. This half-meter copper cable integrates a 100G Ethernet-optimized (100 GbE) 38-position “board-as-connector” design with zinc die-cast male QSFP+ connectors for superior EMI resistance, minimal insertion loss and low crosstalk for better performance. Ergonomic pull-tab ejectors make connecting to equipment a quick, easy task. Eight-pair wire technology is optimized for bandwidth-intense applications, including 100-Gigabit Ethernet (100GBASE-CR4), 128G Fibre Channel and EDR 4x InfiniBand. Flexible 26 AWG conductors maintain a smooth high-frequency response. The N282-20N-28-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 and QSFP+ ports, as well as RoHS and IEEE 802.3bj.
