TP-Link TL-SM321A-2 Gigabit Single-Mode WDM Bi-Directional SFP

What This Product DoesTP-LINKs TL-SM321A-2 is developed in accordance with the Small Form Pluggable Multi-Source Agreement (SFP-MSA). As a WDM Bi-Directional optical transceiver, TL-SM321A-2 uses an integrated LC Bi-Directional optical interface connector and the data link is up to 2 km in 9/125 m SMF (Single-Mode Fiber).Also, TL-SM321A-2 incorporates the Digital Diagnostic Monitoring (DDM) feature which is compatible with SFF-8472. DDM supports real-time monitoring of the transceiver, and shows parameters including the transceiver current which transmits/receives optical power and operating temperature.TP-Link's TL-SM321A-2 is used for short-and medium distance fiber network in practice, and it provides fast and stable gigabit fiber connection for switches, routers, servers, etc.SpecificationsPACKAGE CONTENTSPackage Contents: SFP Module TL-SM321A-2 Installation GuideHARDWARE FEATURESDDM:YesSFP-MSA:YesHot Swappable:YesMEDIA CONVERTER & MODULEStandards and Protocols:IEEE 802.3z, TCP/IPWave Length:TX: 1550 nmRX: 1310 nmDimensions (W*D*H):2.2*0.6*0.5 in (55.4*14.6*12.9 mm)Power Supply:3.3 VSafety & Emission:FCC, CECable:Single-Mode FiberFiber Type:9/125 m Single-ModeMax.
