DEM-CB300QXS is a 40G Direct Attach Copper (DAC) cable designed for high-speed network infrastructure deployments. This passive twinax assembly delivers 40 Gigabit Ethernet connectivity at a length of 3 meters (approximately 118 inches), making it a cost-effective alternative to fiber-based optical transceivers in short-reach switch-to-switch or switch-to-server applications. Network engineers and data center technicians install this cable where low latency and minimal power consumption are priorities in structured cabling and top-of-rack connectivity setups.\u003c\/p\u003e\n\u003cp\u003eThe DEM-CB300QXS is suited for enterprise data center environments where high-density 40G switching infrastructure requires reliable, fixed-length direct attach interconnects. Typical installation scenarios include connecting 40G-capable switches, routers, and servers within the same rack or across adjacent racks. This cable is categorized under enterprise media converters and is sold as a single unit per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40G DAC twinax construction for high-bandwidth, low-latency connectivity\u003c\/li\u003e\n  \u003cli\u003e3-meter cable length suits same-rack and adjacent-rack deployments\u003c\/li\u003e\n  \u003cli\u003ePassive design eliminates active components, reducing power draw\u003c\/li\u003e\n  \u003cli\u003ePlug-and-play installation with no additional transceivers required\u003c\/li\u003e\n  \u003cli\u003eCost-effective alternative to active optical cables in short-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style direct attach copper interconnect for 40G-capable enterprise switching and server platforms compatible with the DEM-CB300QXS form factor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified network engineers or structured cabling technicians. Power down or place the target ports in an administratively disabled state before seating or removing DAC cables to avoid interface errors. Verify that the connected devices support the 40G QSFP DAC form factor before installation. Follow applicable data center cabling standards and manufacturer port density guidelines when routing cables in high-density enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Rate\u003c\/strong\u003e: 40G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Type\u003c\/strong\u003e: Direct Attach Copper (DAC)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 3 meters (approximately 118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: D-LINK SYSTEMS,INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DEM-CB300QXS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"D-LINK","offers":[{"title":"Default Title","offer_id":51561512927538,"sku":"DEM-CB300QXS","price":1024.45,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/d-link-systems-inc-dem-cb300qxs-40g-dac-cable","provider":"Voomi Supply","version":"1.0","type":"link"}
