The Difference Between Single Mode and Multi Mode Fiber Optics

The Difference Between Single Mode and Multi Mode Fiber Optics

You’ve probably heard the terms “single mode” and “multi mode” fiber optic cables. But what’s the difference between single mode and multi mode fiber optics? Well, it’s pretty simple – but you have to go INSIDE the cable for the answer.

Difference Between Single Mode and Multi Mode Fiber Optics

Basically, the main difference with each type of fiber optic cable is the interior size.

    • Single mode fibers consist of a tiny glass core that typically has a diameter between 8.3 and 10 microns (9 microns is a popular size). The single glass strand carrier higher bandwidth than multi mode fiber optic. However, the single mode fiber optic uses one light source in a tight spectral width. The result? Single mode fiber optic is your best choice for transferring high speed data over long distances. Their unique properties make single mode less susceptible to attenuation than multi mode fiber optics.
    • Multi mode fibers contain much larger cores than single mode. Their cores are anywhere from 5 to 7 times larger than single mode cores. With a diameter ranging between 50 to 62.5 microns, multi mode fiber optics can accommodate a higher data volume than single mode. But with the greater capacity comes a setback – multi mode fiber optics have higher attenuation levels, so they’re typically used over shorter distances.

When choosing fiber optic cable for your network, the key considerations should be attenuation and distance. If you need to transmit less data over longer distances, use single mode fiber optic cables. For a greater data capacity over shorter distances, go with multi mode fiber optic cables. Multi mode is often used for LANs and other small networks.

Why Fiber Optic Cables are Better Than Copper

Making the switch from copper cable to fiber optic cable? We understand that you may be asking why. There are many beneficial reasons. When trying to decide whether to buy fiber optic cables or regular, copper cable ones, it’s essential to understand just what fiber optics are and how they can benefit your network.

Why Fiber Optic Cables are Better Than Copper

Fiber Signal more Secure and Clear

To put it simply, fiber optics is a technology that uses glass fibers instead of copper conductors to transmit data. Each of those glass fibers that are bundled together are capable of sending messages adjusted onto light waves. Because fiber transmits the signal through glass in the form of light, it does not conduct electricity—they do not require grounding and they are not susceptible to electromagnetic interference. This means that fiber optics have an extremely secure signal and maintains a very clear signal (virtually noise free).

More Information, Faster

Fiber optic cable transmits information digitally, giving it the ability to carry higher bandwidths at higher speeds, meaning more information, less waiting, and over longer distances. Copper cable can’t compare to fiber optics in bandwidth and speed capabilities.

Ease of Installation

Fiber optic cables are thinner and lighter than copper cables, which makes maneuvering them much easier. With copper cable being much more bulky, it is often difficult to make changes in your current network without drastic changes. If you are installing a new fiber network or just replacing lines, they can be easily placed in existing areas where runs are made.

Less Corrosive

However, these advantages don’t come without some cost. Due to their sophisticated nature, they are more fragile than copper wires and more expensive to install. But this also comes with an advantage—cable damage and failure is detected early and immediately. The benefit is that fiber optic cable does not corrode and is not as sensitive to water and chemical damage, meaning that correctly installed, they last for a long time. (continue reading…)
