Applications

An Ethernet to Fiber Media Converter can also be used where there is high level of electromagnetic interference or EMI which is a common phenomenon found in industrial plants. This interference can cause corruption of data over copper-based ethernet links. Data transmitted over fiber optic cable however is completely immune to this type of noise. An Ethernet to Fiber Optic Converter therefore enables you to inter-connect your copper-ethernet devices over fiber ensuring optimal data transmission across the plant floor.

Converting Ethernet from Copper to Fiber and Back

 

 

Fiber optic technology is taking the Ethernet networking world by storm. It is faster, completely resistant to EMI/RFI, and offers incredible distances between nodes. But fiber is not quite ready for all LAN applications, and in many cases it makes sense to keep a copper network intact and lay a fiber network over it. So we find a need in our industry for a device that will convert between the fiber optic network and the copper network, seamlessly and without loss of speed. We call these devices Ethernet media converters.

 

While we've described Ethernet media converters in a previous newsletter, we'll talk now about the different features available in an Ethernet media converter, and how you can select the right one for your application.

Industrial vs. Commercial

 

The first choice you need to make is whether your Ethernet media converter will be installed in a commercial environment, such as a typical office or clean room, or an industrial environment, which includes places with dust, moisture, temperature variations, vibrations, and other complications.  We've gone over the differences between the two in regards to switches before, but the same rules apply for media converters.

 

It is very important not to confuse the two. While an industrial Ethernet media converter can operate in a commercial environment, it costs more and may not be as easy to put it out of the way. On the other hand, a commercial Ethernet media converter should not be used in an industrial environment as network downtime and system failure can occur.

 

Single mode vs. Multimode

 

There are two main "modes" for fiber optic cabling: single mode and multimode. In general, a single mode system is more expensive, but also provides better signal strength over large distances (up to 80km). Multimode is much more affordable and can be used in distances of up to 2km, depending on network speed and bandwidth. Again, don't confuse the two! If you are running multimode cable, you need a multimode Ethernet media converter or a single mode version will not work.

 

Fiber optic cables have their own unique connector types. There's a good video explaining fiber connectors here. Unlike copper, however, fiber connectors are very difficult to install properly in the field, and there are not a lot of options for converting a connector type with a passive adapter. It is best to match the connector type with the device so they can be easily connected. Remember, Sopto stocks hundreds of factory terminated fiber optic cables off-the-shelf, and can custom manufacture fiber cables without minimum order quantities and with very short lead times, so you don't need to re-terminate or adapt a mismatched cable.

 

Other Features

 

Before ordering your media converter, consider things like mounting method (DIN rails, 19" racks or chassis, or just placed on a shelf), network speed (10/100/1000 Mbps), and how you will get power to the unit. A properly installed media converter can both future-proof and provide redundancy for your network for years to come!
