Combines 8 SFP channels operating at up to 50 Gbps into one affordable 400GbE cable that complies with QSFP-DD MSA specifications.

  • Supports data speeds up to 400 Gb for newer switches and network devices
  • Recommended for high-density switches that support QSFP-DD transceivers
  • Push/pull tabs on QSFP-DD plugs for easy one-handed connection/disconnection
  • Backward compatible with 40/100 GbE networks to facilitate future-proofing
  • Ideal for short connections in data centers, telco rooms and enterprise wiring closets


QSFP-DD Cable Connects High-Density Network Equipment at Speeds Up to 400 Gbps
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.
