ADD-FMCPD-LX-2ST is a Media Converter that converts a 100Base-TX(RJ45) to 100Base-LX(ST) via a 1310nm single-mode fiber (SMF) ST connector, which allows distance reach up to 20km. ADD-FMCPD-LX-2ST provides a cost effective conversion from 100Base Copper to 100Base-LX fiber, while extending the network reach beyond the 100m reach limitation of copper.The ADD-FMCPD product series of media converters allows two types of network segments to be connected easily. The DC/DC powered PoE media converter is a Powered Device (PD) that complies with IEEE802.3af standard, which combines data transferred over a fiber optic link with a DC/DC converter, accepting power from IEE802.3af Power Sourcing Equipment (PSE) over CAT5 and up UTP cable (cable length up to 100meters/330feets). Addoncomputer Media Converters and Network Interface Cards are 100% compliant for all of our networking needs. Now you have a cost effective solution to your network upgrade needs. With our ADDON CERTIFICATION TEST Program, we can guarantee your product will work right the first time.General Information for 100Base-TX To 100Base-LX ST SM 1310nm POE Pwd Media ConverterManufacturer: AddOnManufacturer Part Number: ADD-FMCPD-LX-2STBrand Name: AddOnProduct Name: 100Base-TX To 100Base-LX ST SM 1310nm POE Pwd Media ConverterProduct Type: Transceiver/Media ConverterInterfaces/PortsTotal Number of Ports: 2Network (RJ-45): YesDVI: NoUSB: NoManagement Port: NoNumber of Network (RJ-45) Ports: 1Number of ST Ports: 1Media & PerformanceMedia Type Supported:Optical FiberTwisted PairFiber Mode Supported: Single-modeMaximum Distance Supported: 12.43 MileFiber Optic Cable Standard: 9/125 ÃÂõmNetwork & CommunicationEthernet Technology: Fast EthernetNetwork Technology:10/100Base-TX100Base-LXPhysical CharacteristicsForm Factor: ExternalHeight: 1"Width: 3"Depth: 4"Weight (Approximate): 3.20 ozMiscellaneousGreen Compliant: YesGreen Compliance Certificate/Authority: RoHSWarrantyLimited Warranty: 3 Year
