Feature:1. 1.25Gb/s Rate: 1.25Gb/s rate, 1310nm dual fiber single mode, up to 20KM transmission distance; with advanced DDM function, it can monitor real time parameters and status on the fiber link. SFP MSA compliant, IEEE 802.3z compliant.2. Plug and Play: Hot swappable, rotate the rings fastener down to unlock, then pull the transceiver out of the switch. Less than 1.05W power dissipation and thermal pads provide superior heat dissipation.3. Low Power Consumption: Power consumption is only less than 1 watt, which can save cost wisely. Innovative and cost effective optical network solutions will always be provided.4. Wide Compatibility: Compatible with multi brand devices, widely used in fiber optic switches, routers, net cards, servers, firewalls or other fiber optic equipment with 1.25Gb SFP ports.5. Rigorous Testing: All products are manufactured under strict quality control system, and each module is tested one by one on different switches before leaving the factory to ensure compatibility with switches of different brands.Specification:Item Type: 1.25G SFP Optical ModuleMaterial: Zinc AlloyModel: SFP GE LX SM1310Color: SilverSpeed: 1.25GTransmission Distance: 20KMWorking Wavelength: 1310nmLuminous Optical Power: -9 to -3dbAcceptance Sensitivity: -24dbInterface: LCApplicable Equipment: Widely Compatible with Multi Brand Switches, Routers, Firewalls, Network Cards and Other Equipment.Package List:1 x SFP Optical Module1 x Dust Plug
