Working principle of Ethernet media converters
Let me introduce you to the working principle of Ethernet media converters in detail.
How media converters achieve interconnection between different physical interfaces:
The core function of Ethernet media converters is to convert Ethernet signals of different physical media types to each other, thereby achieving interconnection and communication between heterogeneous interfaces. The specific working process is as follows:
1. Signal reception:
- A physical interface (such as optical fiber) of the converter receives the Ethernet data signal.
- The transceiver circuit of the interface converts the optical signal into an electrical signal and sends it to the internal processing.
2. Signal processing:
- The converter contains a dedicated signal processing circuit that can identify and process different types of Ethernet signals.
- The circuit module will amplify, filter, encode and process the received signal to meet the requirements of the target media.
3. Signal transmission:
- After internal processing, the converter will output the signal to another physical interface (such as copper cable).
- The transceiver circuit of the interface converts the electrical signal into the corresponding physical signal and sends it out.
Through the complete process of signal reception, processing and transmission, the media converter realizes the mutual conversion and interconnection between different Ethernet interfaces.
Functions of key circuit components in the conversion process:
1. Transceiver circuit:
- Responsible for converting different types of physical signals (light, electricity) to each other.
- Such as the photoelectric transceiver circuit of the photoelectric converter, and the cable transceiver circuit of the electrical-to-electric converter.
2. Signal processing circuit:
- Amplify, filter, encode and process the received Ethernet signal.
- Ensure that the converted signal meets the technical specifications of the target media.
3. Microcontroller unit:
- Responsible for controlling the entire conversion process and coordinating the work of various components.
- According to the detected signal conditions, adjust the conversion parameters to optimize performance.
4. Power management circuit:
- Provide stable working power for each module of the converter.
- Ensure that the converter can operate reliably and resist power interference.
In short, Ethernet media converters achieve efficient conversion and interconnection between different Ethernet physical interfaces through key components such as transceiver circuits, signal processing circuits, and microcontrollers.
Main performance indicators of Ethernet media converters
Let me introduce you in detail the main indicators that affect the performance of Ethernet media converters, and how to choose a suitable converter according to actual needs.

- For applications with high latency requirements, it is necessary to select a converter with lower latency.
3. Compatibility:
- The converter needs to support various common Ethernet physical interface standards.
- Ensure that it can be interconnected with existing devices without additional modification.
4. Power consumption:
- The power consumption level of the converter will affect the energy consumption and heat dissipation requirements of the device.

- For low-speed applications, a converter with 100M bandwidth can be selected to reduce costs.
2. Delay sensitivity:
- For applications with high real-time requirements, a converter product with low delay should be selected.
- For scenarios with low delay requirements, the cost factor can be appropriately weighed.
