Fiber optic converter is a media conversion unit of Ethernet transmission that exchange short-distance twisted-pair electrical signals with long-distance optical signals. The function of fiber optic converter is to convert optical signals into electric signals, and send it out, at the same time, convert optical signals received into electric signals and input to the receiver.
Fiber optic converter is typically used in real-world environments where the Ethernet cable can not cover and fiber must be used to extend the transmission distance. At the same time, it also play an important role in connecting the last mile of the fiber to the metropolitan area network and outer network. Fiber optic converter is also an inexpensive solution for the system which needs to upgrade from copper to fiber and for the user who lacks funds, manpower or time.
Fiber optic converter typically has some basic characteristics:
- Providing ultra-low latency data transmission.
- Completely transparent to network protocols.
- Using special ASIC chip to realize data-line forwarding. Programmable ASIC gathers multiple function on a single chip, offering the advantages of simple design, high reliability and low power consumption, resulting in higher performance and lower cost.
- Rack-type devices can provide hot-swapping function for easy maintenance and uninterrupted upgrade.
- The network management equipment can provide network diagnostics, upgrade, status report, abnormality report, control and can provide a complete operation and alarm log.
- The device uses one plus one power supply design which supports ultra-wide power supply voltage to realize power protection and automatic switching.
- Supporting ultra-wide operating temperature range.
- Supporting a complete transmission distance (0-120 km).
Nowadays, a wide range of fiber optic converters are on the market, but in general, there are two types. One is applied in the connection network of copper and fiber optic cables, the other is applied in connection network of fiber optic cables. These two types of fiber optic converters can be divided into different subcategories. The following part will focus on the type of Ethernet optic converter.
Ethernet fiber optic converter is a kind of bidirectional transparent converter which provides Ethernet data signals to fiber data signals. It can transmit Ethernet signals along the fiber optic line and break the transmission distance limit of one hundred meters, allowing Ethernet network coverage to be great extended. Fiber optic data communication has been widely used in various fields because it has long communication distance, large capacity of data communication and is not easy to be disturbed. The original network systems were based on cable communication, but fiber optic converter can ensure the smooth conversion between electric signals and fiber optic signals. It is suitable for Ethernet network environment where high-speed, high data transfer, high performance and high reliability are needed, such as telecommunication, broadcasting, broadband network and so on.
In general, Ethernet fiber optic converter can be divided into three types. They are standalone media converter, industrial media converter and chassis-based media converter.
The standalone media converter is suitable for single user. Compared with other Ethernet fiber optic converter, standalone media converter is characterized with small size, low price, so it can greatly save space and cost. The structure of standalone media converter is compact and it is often deployed in racks, distribution boxes and other places where space is limited. Its plug-and-play packaging allows users to install and use quickly.
Industrial Media Converter
The industrial media converter is often used in harsh environment, such as high-speed tunnels, subways, sewage treatment, steel factory and so on. It can adapt to low temperature and high temperature. It has strong anti-lightning ability and anti-vibration ability.
Chassis-based Media Converter
Chassis-based Media Converter is a kind of fiber optic converter in the form of chassis structure. The power supply can achieve double automatic backup uninterrupted work and the system has over-temperature, over-voltage and over-current protection device. The internal adopts voltage compensation technology that fiber optic converter module can obtain reliable, accurate voltage supply. Chassis-based media converter is suitable for multi-user application. At present, many domestic chassis are sixteen-slot type products, that is, a chassis can be inserted up to sixteen fiber optic converter modules and each fiber optic converter module can operate independently or cooperate with each other in the rack.
As a kind of photoelectric conversion device, the Ethernet fiber optic converter can convert electrical signals into optic signals and transmit them in single-mode or multimode fiber optic cable, breaking the cable transmission limit of short distance and making use of fiber media to achieve a few or even hundreds of kilometers of long-distance transmission with high-bandwidth.
