    Specifications

    Nvidia/Mellanox MCA4K50 (980-9IAM5-00X001) Compatible 1.6T OSFP224 IHS/Closed Finned Top InfiniBand XDR ACC Cable (1m, Active, 26 AWG, 0-70°C, OSFP224 to OSFP224)

     

    The NVIDIA/Mellanox MCA4K50 (980-9IAM5-00X001) compatible OSFP224 ACC is a 1600Gb/s (Twin-port 2x800Gb/s) IHS/Closed Finned Top Active DAC cable. The IHS to IHS (Integrated Heat Sink) closed finned top structure is ideal for connecting air-cooled and liquid-cooled Quantom 3 Infiniband XDR switches (i.e., Q3400-RA, Q3200-RA).

     

    The 1.6T OSFP224 ACC cable contains 8x high-speed electrical copper pairs, with each operating at a data rate up to 200Gb/s. Adopting the Pulse-amplitude Modulation at 4-channels (PAM4) modulation, its electrical configuration is based on 8-channels of 200G-PAM4. QSFPTEK manufactured 1.6T direct attach copper cables enable per port higher bandwidth, density and configurability, data center interconnectivity at a cost-effective price and lower power requirement.

      Picked this up for a short intra-rack XDR link between our switches, and it just works. No compatibility issues with our Mellanox gear, and latency is exactly what we expect from copper.

      The DAC cable worked well on our new Q3400-RA switch set! At first, I was concerned about compatibility, but it truly appears to be a module brand that offers both stability and great value for money.
