The media converter has an SFP slot allowing for cooperation with multimode or single-mode optical fibers, depending on the module chosen. All-optical transmission parameters depend on the SFP module. TP-LINK MC220L can cooperate with SFP modules compliant with IEEE 802.3z 1000Base-FX standard. The device supports MDI/MDIX auto-detection and automatically finds and sets the fastest connection speed and mode. The “Store and forward” mechanism verifies the received data using the checksum function.TP-LINK MC220L is fully compatible with 1000BaseTX/FX standard. Its installation is very simple thanks to the “Plug and Play” feature. The LED indicators show the current operating status. Media converters with interchangeable SFP modules can operate in multimode and single-mode networks (transmission via two optical fibers or via single fiber, with the use of modules based on WDM or CWDM technology). The solution is especially cost-effective in the case of plans for the future expansion of the network (it is sufficient to exchange only the SFP modules).
