It provides a practical solution for network installations where only one fibre core is available but data must travel in both directions.\u003c\/p\u003e\u003cp\u003eUsing BiDi (Bidirectional) and WDM (Wavelength Division Multiplexing) technology, the pair sends and receives optical signals at different wavelengths through the same fibre core. Module A transmits at 1310nm and receives at 1550nm, while Module B transmits at 1550nm and receives at 1310nm.\u003c\/p\u003e\u003cp\u003eWith a specified transmission distance of up to 20KM and a data rate of 1.25Gbps, these modules are suitable for compatible Gigabit Ethernet switches, routers, fibre media converters and other network equipment with SFP ports.\u003c\/p\u003e\u003cp\u003eEach module uses an LC optical interface and a standard SFP form factor. For correct operation, the A and B modules must be installed at opposite ends of the fibre link as a matched pair.\u003cbr\u003e1.25Gbps data rate\u003cbr\u003eTransmission distance up to 20KM\u003cbr\u003eBiDi\/WDM single-fibre technology\u003cbr\u003eDesigned for single-mode fibre\u003cbr\u003eModule A: TX 1310nm \/ RX 1550nm\u003cbr\u003eModule B: TX 1550nm \/ RX 1310nm\u003cbr\u003e\u003cstrong\u003eLC optical connector\u003c\/strong\u003e\u003cbr\u003eStandard SFP form factor\u003cbr\u003eBidirectional communication over one fibre core\u003cbr\u003eSuitable for compatible Gigabit Ethernet equipment\u003cbr\u003eIdeal for network extensions and fibre installations with limited cores\u003cbr\u003eSpecification\tModule A\tModule B\u003cbr\u003eModel\tSFP-WDM-SM-0220A\tSFP-WDM-SM-0220B\u003cbr\u003eData Rate\t1.25Gbps\t1.25Gbps\u003cbr\u003eTransmission Distance\tUp to 20KM\tUp to 20KM\u003cbr\u003eFibre Type\tSingle Mode\tSingle Mode\u003cbr\u003eTechnology\tBiDi \/ WDM\tBiDi \/ WDM\u003cbr\u003eTransmit Wavelength\t1310nm\t1550nm\u003cbr\u003eReceive Wavelength\t1550nm\t1310nm\u003cbr\u003eOptical Connector\tLC\tLC\u003cbr\u003eFibre Configuration\tSingle Fibre\tSingle Fibre\u003cbr\u003eForm Factor\tSFP\tSFP\u003cbr\u003eApplication\tGigabit Ethernet\tGigabit Ethernet\u003c\/p\u003e","brand":"Alcell","offers":[{"title":"Default Title","offer_id":57593165775014,"sku":"SFP-WDM-SM-0220A\/B","price":279.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/3047\/5311\/files\/sfp-wdm-sm-0220a-b-1.jpg?v=1791529847","url":"https:\/\/alcell.co.za\/products\/sfp-1-25g-20km-pair-t1310-r1550nm-lc","provider":"Alcell","version":"1.0","type":"link"}
