Supplied on a 1000-foot pull box, it is designed for structured cabling runs between floors in commercial and residential buildings. The CMR (Communications Multipurpose Cable, Riser) rating satisfies fire propagation requirements for vertical shaft and riser pathways. Network installers and low-voltage technicians use this cable to terminate horizontal and backbone runs to patch panels, switches, and wall jacks in standard Ethernet infrastructure.\u003c\/p\u003e\n\u003cp\u003eThis cable suits horizontal and riser backbone cabling in office buildings, schools, healthcare facilities, and multi-family residential projects. It supports 10BASE-T, 100BASE-TX, and 1000BASE-T (Gigabit Ethernet) network applications. The 1000-foot box format is standard for pulling long runs through conduit or cable trays without intermediate splices.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCategory 5e performance supporting Gigabit Ethernet and 100 MHz bandwidth applications\u003c\/li\u003e\n  \u003cli\u003eU\/UTP construction with 4 unshielded twisted pairs for straightforward termination\u003c\/li\u003e\n  \u003cli\u003eCMR riser-rated jacket meets fire propagation requirements for vertical runs per NEC Article 800\u003c\/li\u003e\n  \u003cli\u003e1000-foot pull box packaging for efficient installation on long cable runs\u003c\/li\u003e\n  \u003cli\u003eSuitable for conduit, cable tray, and open plenum-adjacent riser pathways where CMR is the required rating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style structured cabling solution compatible with standard Cat5e keystone jacks, patch panels, and RJ-45 connectors in T568A and T568B termination configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed low-voltage or data cabling technician in accordance with NEC Article 800 and TIA-568 standards. De-energize and verify lockout of any adjacent powered pathways before pulling cable through conduit or riser sleeves. Maintain minimum bend radius and avoid exceeding the cable's pull-tension rating during installation to prevent pair distortion. Terminate both ends using a punch-down tool or crimp tool rated for Cat5e to ensure proper pair geometry and signal performance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Standard\u003c\/strong\u003e: Category 5e\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePair Configuration\u003c\/strong\u003e: 4-Pair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShielding\u003c\/strong\u003e: U\/UTP (Unshielded Twisted Pair)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJacket Rating\u003c\/strong\u003e: CMR (Riser)\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 Unit\u003c\/strong\u003e: 1 box (1000 ft)\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: BELDEN INC.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1583A 004U1000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELDEN","offers":[{"title":"Default Title","offer_id":51685633720626,"sku":"1583A 004U1000","price":634.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27f538b4ea3421f6792fa66ac80af28b_d2ba1ef5-e1f0-4ee5-9140-d676b928fe07.jpg?v=1788216872","url":"https:\/\/voomisupply.com\/products\/belden-inc-1583a-004u1000-cat5e-utp-cmr-riser-cable","provider":"Voomi Supply","version":"1.0","type":"link"}
