Port Specifications
Ethernet ports: 10/100/1000Base-T adaptive rates are most likely supported, and the RJ-45 connector is a common Ethernet connector type that facilitates connection using standard Cat5e, Cat6, or higher Ethernet cables. Ideally, with standard cables, the Ethernet port can transmit data over a distance of up to 100 metres, which meets the need for short-distance wiring between most devices in industrial sites, and can be seamlessly connected to various Ethernet devices, such as industrial controllers, smart sensors, computers, and so on.
Fibre optic port: Considering the demand for long distance and high bandwidth transmission in industrial scenarios, it is assumed that this media converter is equipped with a fibre optic port. If the media converter is equipped with a multi-mode optical fibre port, the transmission distance may reach 550m when using 50/125μm optical fibre with a transmission rate of 1000Mbps, which is suitable for data interaction between devices in different workshops within a factory, such as connecting devices in different production areas of an electronics manufacturing factory.
If equipped with single-mode fibre ports, using 1310nm wavelength single-mode fibre, the transmission distance can be significantly extended to several kilometres, which is important for cross-factory data communication in large industrial parks or long-distance data transmission scenarios, such as in smart grids, between a substation and a remote monitoring centre. Fibre optic ports may be of SC or LC type, which are easy to plug and unplug and have a solid connection.
Electrical parameters: the operating voltage may be designed to adapt to the common voltage range of industrial environments, such as supporting a wide voltage input of 100 – 240V AC, 50/60Hz AC frequency, which is able to operate stably in different regions and different power supply conditions in industrial sites, reducing the risk of equipment failure due to voltage fluctuations or mismatches.
In terms of DC power supply, DC 12V or other suitable DC voltage may be used for power supply, depending on the design of the internal power management module of the device, DC power supply provides stable power support for the device to meet the requirements of industrial automation scenarios with high power stability. The power consumption of the device depends on the internal circuit design and processing capability, and is optimised as much as possible to reduce operating costs and energy consumption while ensuring efficient data conversion and processing.

This enables the media converter to communicate and interact with different brands and types of industrial automation equipment. For example, in an industrial automation production line that contains multiple brands of controllers and sensors, by supporting Modbus TCP protocol, the media converter can efficiently convert and transmit the data of the devices that use this protocol to achieve the interconnection of the entire production line equipment and collaborative work, reducing the difficulty and cost of system integration.
Performance Advantages
Efficient data conversion performance
Fast signal processing: the internal probability of using high-performance special chips and optimised circuit design, to achieve fast and accurate conversion of optical and electrical signals. In industrial automation production lines, a large amount of sensor data need to be transmitted and processed in real time, MM20 – M4M49999TAHH media converter can complete the signal conversion in a very short period of time, to ensure the timeliness of data.
In automotive production lines, for example, where sensors used to detect the position and size of parts generate a large amount of data per second, the media converter can quickly convert the data transmitted over fibre optics into Ethernet signals for transmission to the back-end control system, thus guaranteeing production efficiency and product quality.
Low-latency data transmission: During the data conversion process, internal algorithms and hardware architecture are optimised to reduce latency as much as possible and ensure real-time data transmission. For industrial applications such as robot control and motion control that require high real-time performance, low-latency data transmission is essential. The media converter controls data latency to a very low level, ensuring that data from the front-end device is transmitted quickly and accurately to the target device, avoiding control errors or production accidents caused by latency.

For example, the media converter can work reliably in the high-temperature smelting workshop of a steel factory, the underground working environment of a coal mine, etc. to ensure the stability of the network connection.
Redundant design guarantee: some models may adopt redundant power supply design, equipped with two or more power input interfaces, when one power supply fails, the other power supply automatically takes over the work, to ensure continuous operation of the equipment, to avoid data transmission interruption caused by power failure.
In terms of network connection, it may support the link redundancy function, data transmission through multiple network links, when a link fails, the data will be automatically switched to other normal links to ensure uninterrupted network communication. This redundancy design is of great significance in industrial application scenarios that require high network reliability, such as the monitoring network of the power system, the control system of chemical production, etc. It can effectively improve the reliability and stability of the entire industrial network .
Network Security Enhancement
Network isolation function: while performing signal conversion, it realises effective isolation between different network areas. It can prevent unnecessary network traffic from spreading between different networks and reduce the impact of potential network attacks on the entire network system.
For example, in substations in the power industry, networks in different functional areas, such as primary equipment monitoring network and secondary equipment protection network, are isolated by the media converter, so that even if the network in a certain area suffers from a malicious attack, the attack can be prevented from spreading to other areas to the maximum extent possible, to ensure the stable operation of the power system network, and to ensure the reliability of the power supply.
Security protocol support: It may support a variety of network security protocols, such as SSL/TLS encryption protocol, to encrypt the transmitted data, preventing the data from being stolen or tampered with in the transmission process. In the era of Industrial IoT, a large amount of industrial data is transmitted over the network, and data security is crucial.
By supporting security protocols, the MM20 – M4M49999TAHH media converter provides security for industrial data transmission, ensures that enterprise production data and business secrets are not leaked, and meets the strict requirements of industrial enterprises for network security.
