By integrating silicon photonics directly with the InfiniBand switch ASIC, the Q3450-LD eliminates the need for pluggable optical transceivers--reducing electrical loss, enhancing signal integrity, and improving overall power and thermal efficiency. With 144 800Gb\/s ports connected via direct MPO connectors, the Q3450-LD delivers unmatched port density and radix--ideal for building high-performance AI fabrics at scale. CPO technology reduces the high-speed electrical path to just a few millimeters within the substrate, slashing insertion loss to ~4 dB--compared to 22 dB in traditional pluggable designs. This results in 63x better signal integrity, enabling higher data rates with lower DSP complexity and reduced power per bit.\u003cbr\u003eAs part of the NVIDIA Quantum-X800 InfiniBand platform, the Q3450-LD is purpose-built for AI workloads that require ultra-low latency, high bandwidth, and deterministic performance across multiple thousands of GPUs. It also simplifies thermal design and cable management, accelerating the deployment and scaling of power-efficient InfiniBand-based AI Factories.\u003c\/p\u003e\n\u003cp\u003eEnvironmental\u003cbr\u003eTemperature:  Operational: Reverse air flow: 5° to 40°C  |  Non-Operational: -40° to 70°C\u003cbr\u003eHumidity:  Operational: 10%-85% non-condensing  |  Non-Operational: 10%-90% non-condensing\u003cbr\u003eAltitude:  3050m\u003cbr\u003eNoise level:  TBD\u003c\/p\u003e\n\u003cp\u003eRegulatory\u003cbr\u003eSafety:  CB, cTUVus, CE, CU\u003cbr\u003eEMC:  EMC: CE, FCC, VCCI, ICES, RCM\u003cbr\u003eRoHS:  RoHS compliant\u003c\/p\u003e\n\u003cp\u003ePower\u003cbr\u003eInput Voltage:  2x DGX Compliant Bus Bar connectors, 40V – 60V input voltage\u003cbr\u003eGlobal Power Consumption:  Max power with active cables: TBD\u003c\/p\u003e\n\u003cp\u003eMain Devices\u003cbr\u003eCPU:  Intel CFL 4 cores i3-8100H 3GHz\u003cbr\u003eSwitch:  Quantum-3\u003c\/p\u003e\n\u003cp\u003eThroughput\u003cbr\u003eSwitching:  115.2 Tbps\u003cbr\u003eSpeed:  400\/800Gb\/s per port\u0026lt;\u003c\/p\u003e\n\u003cp\u003eMechanical\u003cbr\u003eSize:  4U, 6.89\" (H) x 17.24\" (W) x 33.07\" (D)\u003cbr\u003eMounting:  19” rack mount\u003cbr\u003eWeight:  57.20 kg\u003cbr\u003eSpeed:  400, 800Gb\/s per port\u003cbr\u003eConnector cage:  144 MPO connectors\u003cbr\u003eLiquid cooling connection type:  4xUDQ4\u003c\/p\u003e","brand":"Nvidia","offers":[{"title":"Default Title","offer_id":42412213960798,"sku":"920-9B36M-00MX-8QS","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0074\/1667\/6404\/files\/920-9B36M-00MX-8QS.jpg?v=1768944817","url":"https:\/\/www.itbargaincenter.com\/products\/920-9b36m-00mx-8qs-rf","provider":"ITBargainCenter","version":"1.0","type":"link"}
