It uses wavelength-division multiplexing (WDM) technology to transmit and receive data over a single strand of single-mode fiber, eliminating the need for a fiber pair. This module is installed by network technicians and IT infrastructure professionals in environments where fiber port density or cable runs make single-fiber operation practical and cost-effective.\u003c\/p\u003e\n\u003cp\u003eThe SM321B is suited for enterprise, commercial, and light industrial network deployments where Gigabit fiber uplinks are required. It fits into any standard SFP slot and supports 1000BASE-BX operation over single-mode fiber. Typical install scenarios include switch-to-switch uplinks, server room backbone runs, and building-to-building fiber connections where single-fiber cabling infrastructure is already in place.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1000BASE-BX standard for Gigabit Ethernet over single-mode fiber\u003c\/li\u003e\n  \u003cli\u003eWDM bidirectional design uses a single fiber strand for both transmit and receive\u003c\/li\u003e\n  \u003cli\u003eStandard SFP form factor for broad switch and router compatibility\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style SFP transceiver for use in standard SFP-slot-equipped Gigabit Ethernet switches, routers, and media converters supporting 1000BASE-BX single-mode fiber.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified network technicians following applicable data cabling and equipment standards. Power down or hot-swap according to the host device manufacturer guidelines before inserting or removing the SFP module. Clean fiber end-faces before mating connectors to prevent signal loss. Do not expose the optical ports to direct light or dust when the module is not connected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: 1000BASE-BX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTechnology\u003c\/strong\u003e: WDM Bidirectional (Bi-Di)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: SFP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFiber Type\u003c\/strong\u003e: Single-Mode\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 1 each\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: TP-LINK USA CORPORATION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SM321B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TP-LINK","offers":[{"title":"Default Title","offer_id":51686085230898,"sku":"SM321B","price":65.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd445346102a8ba2704616fa9aff5c9.jpg?v=1788222122","url":"https:\/\/voomisupply.com\/products\/tp-link-usa-corporation-sm321b-1000base-bx-sfp-module","provider":"Voomi Supply","version":"1.0","type":"link"}
