How To Correctly Apply And Maintain The Industrial Media Converters?

Media Converter is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It is also called fiber converter in many places. The products are generally used in the actual network environment where the Ethernet cable cannot cover and the optical fiber must be used to extend the transmission distance, and are usually positioned in the access layer application of the broadband metropolitan area network; Such as: high definition video image transmission of monitoring safety engineering; At the same time, it has also played a huge role in helping to connect the last kilometer of optical fiber lines to the metropolitan area network and the outermost networks. The specific functions are as follows:

1. Media converters can not only realize the interconnection between Ethernet switches, but also between ethernet switches and computers, computers and computers.

2. Transmission relay: when the actual transmission distance exceeds the nominal transmission distance of the transceiver, especially when the actual transmission distance exceeds 120km, it is a very economical and effective solution to use two media converters for back-to-back relay or optical to optical converter for relay when site conditions permit.

3. Single multimode conversion: when single multimode optical fiber connection is required between networks, one single multimode converter can be used for connection, which solves the problem of single multimode optical fiber conversion.

4. In wavelength division multiplexing transmission, when long-distance optical cable resources are insufficient, in order to improve the utilization rate of optical cable and reduce the cost, the transceiver and wavelength division multiplexer can be used together to transmit two channels of information on the same pair of optical fibers.

In short, the function of the media converter is to convert the electrical signal we want to send into an optical signal and send it out. At the same time, it can convert the received optical signal into an electrical signal and input it to our receiving end. Industrial media converters are used in many scenarios. How to properly apply and maintain them is the main way to increase the service life of industrial media converters. Then, how to correctly apply and maintain the industrial media converters?

1. During application, ensure the continuous and normal power distribution of the industrial media converter

The laser generator part and photoelectric conversion control module of the media converter avoid the impact of instantaneous surge current, so it is not suitable for automatic switch on and off frequently. The computer room in front of the centralized optical transceiver center and the set point of the 1550nm optical frequency modulation transmitter optical amplifier shall be equipped with UPS switching power supply to maintain the laser components and protect the photoelectric conversion control module from the harm of single pulse large working current.

2. When the industrial media converter is applied, it is necessary to maintain a clean and tidy office environment with natural ventilation, heat removal, waterproof

The laser generator part of the optical frequency modulation transmitter is the heart and blood vessel of the equipment. Considering that in order to maintain the normal operation of the equipment, the manufacturer has installed cooling and heat dissipation system software in the equipment, but when the working temperature nearby exceeds the allowable range, the equipment can not work normally. Therefore, in the extremely hot season, when there are many hot equipment in the central computer room and the standard of natural ventilation and heat removal is poor, It is better to install the air conditioning system software to ensure that the media converter works normally.

3. Industrial media converter should be tested and recorded during application

A microcontroller is set in the media converter equipment to detect the operating state of the internal structure of the system, collect various main parameters of the control module, and visually display them on the LED and VFD display equipment; The audible and visual alarm system software is set in the optical FM transmitter to prompt the check-in staff. The maintenance staff only need to identify the cause of the problem according to the main operating parameters and solve it on time, so as to ensure the normal operation of the system.
