Industrial Gigabit Ethernet to Fiber Media Converter
The EF24S Series is a lite Industrial Gigabit Ethernet to Fiber Converter providing media conversion between 10/100/1000 BASE-T(X) and 1000 BASE-(F)X (available in both SC and SFP fiber connectors). Whether you’re upgrading your system or simply replacing an obsolete device with a newer model, EF24S ensures that the process is both easy and cost-efficient.
On top of basic media conversion, the EF24S Series comes with a DIP switch to configure or enable more advanced functions including flow control, link fail pass-through, and jumbo frame limitation to allow maximal flexibility. Although small and slim, it is no doubt rugged and ready for any application.
The EF24S Series Media Converter also provides auto MDI/MDI-X, Auto Negotiation, and Link Fault Pass-Through (LFP) function and one 3-pin DIP switch to configure the functions, such as the flow control, link fail pass-through, and jumbo frame.
