1000Base-SX?\u003c\/h3\u003e\n\u003cp\u003e1000Base-LX (Long-range) uses 1310nm wavelength and single-mode fibre for distances up to 10km. 1000Base-SX (Short-range) uses 850nm wavelength and multi-mode fibre for distances up to 550m (OM3). Use the SM311LS where your fibre runs exceed 550m or where single-mode fibre is already installed.\u003c\/p\u003e\n\n\u003ch3\u003eWhat fibre cable do I need?\u003c\/h3\u003e\n\u003cp\u003eThe SM311LS requires single-mode fibre (9\/125 µm) with LC\/UPC duplex connectors. Multi-mode fibre is not compatible with this module. Ensure both ends of the fibre link use the same connector type and polish (UPC or APC).\u003c\/p\u003e\n\n\u003ch3\u003eIs the SM311LS compatible with non-TP-Link switches?\u003c\/h3\u003e\n\u003cp\u003eYes. The SM311LS is SFP MSA compliant and is designed to work in any switch or device with a standard SFP port. Compatibility with specific third-party switches may vary — check your switch vendor’s compatibility list or test in your environment.\u003c\/p\u003e\n\n\u003ch3\u003eCan I hot-swap the transceiver without rebooting the switch?\u003c\/h3\u003e\n\u003cp\u003eYes. The SM311LS is hot-pluggable and can be inserted or removed while the switch is powered on without disrupting other ports or requiring a reboot.\u003c\/p\u003e\n\n\u003ch3\u003eDo I need one or two SM311LS modules for a fibre link?\u003c\/h3\u003e\n\u003cp\u003eYou need one SM311LS module at each end of the fibre link — one installed in each switch. A single module only provides one end of the connection.\u003c\/p\u003e","brand":"TP-Link","offers":[{"title":"Default Title","offer_id":43198321950949,"sku":"SM311LS","price":22.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/1554\/1221\/files\/tp-link-sm311ls-omada-1000base-lx-smf-mini-gbic-module.webp?v=1779521803","url":"https:\/\/cctvguru.com.au\/products\/tp-link-sm311ls-1000base-lx-sfp-single-mode-lc-transceiver-10km","provider":"CCTV Guru","version":"1.0","type":"link"}
