Why Do We Need Fiber Optic Media Converters?

Optical fiber is suitable for long distance transmission. Generally, the transmission distance of single-mode fiber is more than 10 kilometers, and the transmission distance of multi-mode fiber can reach 2 kilometers. In the process of optical fiber network transmission, we usually use a device called optical fiber media converter.


1. Reasons for needing fiber optic media converters


As we all know, CAT5/6 can only cover about 100 meters, which is obviously not enough for longer distance transmission. In this case, fiber optic media converter equipment plays a vital role. By converting the Ethernet signal to a fiber optic signal, the distance can be extended to 100 meters to 120KM. During this process, it remains stable and instant; starting from the terminal, it is converted again, enabling the terminal equipment in the network to act as an Ethernet signal again.


Sometimes, converting to fiber is the only technical solution. If you're going to be working in an electromagnetic interference (EMI)-heavy environment - such as heavy machinery, welders, large motors, motor controls, or very high voltages - any copper wire, even the best reinforced Category 5 or 6 There will also be enough interference to prevent low error rate data transmission. The fiber is fully insulated so there is no EMI pickup. In fact, most high-voltage transmission lines have optical fibers in the middle.


2. Optical fiber media converters are widely used in modern network systems


One of the easiest ways to achieve photoelectric conversion is to use optical fiber media converters, which are widely used in modern network systems and are usually used to convert between two different transmission media (optical fiber and copper wire) or to expand the network. However, the function of the fiber converter is not limited to this, it can also realize single-mode-multi-mode, single-duplex and conversion between different wavelengths.


3. Single-mode to multi-mode conversion of fiber optic media converters


Optical fiber media converter When the distance between two connection points in the network system is long, we need to use a single-mode optical fiber cable to transmit optical signals to ensure the normal transmission of signals. Therefore, many network service providers use single-mode fiber optic cables for transmission. Optical signals, and many devices in a data center or enterprise network, are multimode fiber ports. At this time, a device capable of realizing single-mode multi-mode conversion of optical signals is required. The campus network is such a common application. Devices in campus buildings are usually multimode fiber ports, and connections between buildings usually use single mode fiber optic cables.
