Product Overview
The PAMIX MCI-1120 Ethernet Optical Fiber Media Converter is engineered for efficient signal conversion between two 10/100/1000M Ethernet RJ45 ports and a fiber SCD port. Capable of carrying out long-distance data and video signal transmission, it supports both half and full-duplex modes with auto-negotiation. Built for stability, the converter features low power consumption and a double-sided ventilation design, ensuring reliable operation in harsh environments. It supports both single-mode and multi-mode fiber types and can be installed on a desktop, mounted to a wall, or integrated into a rack chassis.
