This twinaxial network cable offers a reliable and efficient connection over a maximum reach of 2.0 meters (6.6 feet), making it ideal for high-speed server-to-switch or switch-to-switch applications. Constructed from high-quality copper, it ensures excellent electrical conductivity and durability, while its low-loss design supports 25G and 50G PAM-4 data rates per channel for optimal performance. The cable is fully compliant with the QSFP-DD MSA Specification Rev 3.4, SFF-8679 electrical interface, and SFF-8636 management interface, ensuring seamless interoperability with compatible hardware. It also adheres to IEEE802.3Bj, IEEE802.3CD standards, supporting high-speed data transfer with robust EMI\/EMC shielding, thanks to its 360-degree cable shield termination. The pull-to-release latch design simplifies installation and removal, reducing risk of damage during handling. Additionally, the cable benefits from advanced automated assembly technologies, providing stronger mechanical features, increased flexibility, and low insertion loss. Certified as TAA compliant and RoHS environmentally friendly, this product is manufactured in the United States by AddOn, with a limited lifetime warranty for peace of mind. Whether deploying new data center infrastructure or upgrading existing systems, the QDD-400-CU2M-AO delivers reliable, high-speed connectivity suited for modern high-bandwidth applications.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCompliant with QSFP-DD MSA Specification Rev 3.4 for interoperability and standards compliance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSFF-8679 electrical interface compliant for seamless integration with compatible hardware\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports SFF-8636 management interface for device monitoring and control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeets IEEE802.3Bj and IEEE802.3CD standards for high-speed data transfer\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSupports 25G and 50G PAM-4 electrical data rates per channel for versatile performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eI2C interface for EEPROM communication ensures device configuration and management\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePull to Release latch design simplifies installation and removal processes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExcellent EMI\/EMC performance with 360-degree shield termination reduces interference\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAutomated pre-solder assembly technology enhances durability and consistency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLow insertion loss combined with stronger mechanical features and flexibility for reliable connections\u003c\/li\u003e\u003c\/ul\u003e","brand":"ADDON","offers":[{"title":"Default Title","offer_id":44575801278506,"sku":"QDD-400-CU2M-AO","price":458.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/1068167926_eae51aa0-37eb-4e2b-aa7f-c01fcea4d680.jpg?v=1784024877","url":"https:\/\/atticusgoods.com\/products\/addon-cisco-qdd-400-cu2m-ao-400gbase-cu-qsfp-dd-to-qsfp-dd-pam-4-passive-copper-direct-attach-cable-2-meters","provider":"Atticus Goods","version":"1.0","type":"link"}
