The 1SFP 1RJ45 PCBA Fiber Media Converter is a core board used to convert signals between fiber optic and copper Ethernet networks. Its primary function is to extend a network by receiving optical signals via its SFP port and converting them for transmission over a standard RJ45 Ethernet cable, or vice-versa. This compact, board-level solution is designed for integration into other devices or enclosures. It is ideally suited for applications such as embedded network systems, industrial control equipment, and cost-effective network extension in SMEs, providing a reliable fiber-copper interface over distances up to several kilometers.
