DEM-QX10Q-LR4 is a 40GBASE-LR4 QSFP+ optical transceiver module designed for high-speed data transmission over single-mode fiber. Operating at 40 Gbps, it uses four wavelength-division multiplexed lanes across a single-mode fiber link. This module is installed by network engineers and data center technicians in switches, routers, and network equipment that support the QSFP+ form factor. It is suited for enterprise and data center environments where long-reach, high-bandwidth fiber connectivity is required.\u003c\/p\u003e\n\u003cp\u003eThe DEM-QX10Q-LR4 is designed for use in enterprise data center and campus network deployments where 40 Gbps single-mode fiber connections are required over extended distances. It fits into QSFP+ slots on compatible network switches and routers. Typical installation scenarios include core-to-distribution links, spine-leaf interconnects, and high-density server aggregation, where reliable long-reach optical transport is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40GBASE-LR4 standard compliance for 40 Gbps transmission over single-mode fiber\u003c\/li\u003e\n  \u003cli\u003eQSFP+ form factor for compatibility with standard high-density switch and router slots\u003c\/li\u003e\n  \u003cli\u003eFour-lane wavelength-division multiplexing (LR4) architecture over a single fiber pair\u003c\/li\u003e\n  \u003cli\u003eLong-reach single-mode design suited for data center and enterprise campus links\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (EA)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and upgrade transceiver for network switches, routers, and line cards equipped with QSFP+ slots supporting the 40GBASE-LR4 standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by qualified network technicians familiar with fiber optic handling procedures. Power down or hot-swap protocols should follow the host equipment manufacturer guidelines before inserting or removing the module. Handle the optical port with care and keep the dust cap in place until the fiber connector is ready to be seated. Consult applicable data center cabling and safety standards for single-mode fiber termination and bend radius requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: 40GBASE-LR4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: QSFP+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFiber Type\u003c\/strong\u003e: Single-Mode\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Rate\u003c\/strong\u003e: 40 Gbps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\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-QX10Q-LR4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"D-LINK","offers":[{"title":"Default Title","offer_id":51557567922482,"sku":"DEM-QX10Q-LR4","price":12547.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/d-link-dem-qx10q-lr4-40gbase-lr4-qsfp-transceiver","provider":"Voomi Supply","version":"1.0","type":"link"}
