TP-LINK 1000Base-BX WDM Bi-Directional SFP Module Up to 2km (TL-SM321A-2)

1000Base-BX WDM Bi-Directional SFP ModuleAdopts the latest standard 1000Base-BXUp to 2 km transmission distance in 9/125 μm SMF (Single-Mode Fiber)Compatible with Small Form Pluggable Multi-Source Agreement (SFP-MSA)Supports Digital Diagnostic Monitoring (DDM)Supports Hot SwappableWhat 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 μm 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. Device TypeBi-Directional SFP ModuleStandards and ProtocolsIEEE 802.3z, TCP/IPCableSingle-mode FiberFiber Type9/125 um Single-ModeData Rate1.25 GbpsWave LengthTX: 1550 nmRX: 1310 nmPort TypeLC SimplexPower Supply3.3 VEnvironment ()Operating Temperature: 070 C (32158 F)Storage Temperature: -4085 C ( -40185 F)Operating Humidity: 1090% RH, Non-CondensingStorage Humidity: 590% RH, Non-Condensing
