The 100M 3-Optical 2-Electrical PCBA Fiber Optic Converter is a compact network solution that efficiently converts between electrical and optical signals. It features three single-fiber SC optical ports and two 100Mbps Ethernet ports, supporting data transmission over 20km using single-mode fiber. This converter operates on standard A/B end wavelengths (1310/1550nm) for bidirectional communication. Its primary function is to extend network coverage while connecting multiple fiber and copper-based devices. Ideal for space-constrained installations, it's commonly used in industrial control systems, small-scale network deployments, and distributed surveillance applications requiring reliable media conversion.
