You’ve probably already heard that fiber optic internet is faster than traditional cable but did you know it is also less susceptible to outages, interruptions, and security breaches? Below, we take a closer look at the factors that differentiate fiber and cable internet, and what these differences mean for your business productivity, customer satisfaction, and bottom line.

The Basics
A fiber optic cable is a network cable that contains small strands of glass inside an insulated casing.  The fiber optic cables transmit information using pulses of light, making it more advanced that traditional cable.

Most cable internet companies now utilize coaxial (coax) cable, a type of cable made of a copper core with a metal shield, to carry communication signals.  Data is sent via electricity over coaxial cables, which is fast but just can’t match the speed of light.

As noted above, data transmitted by light is inherently faster than data transmitted by electricity.  For example, the most advanced cable internet currently on the market uses DOCSIS 3.1, a new technology that allows coax cable to achieve speeds of 10 GB upload and download.  In comparison, in 2014, researchers reached speeds of 32 terabytes (TB) per second over a one kilometer stretch of fiber.  “That is roughly the total sum of all traffic flowing across the internet at peak times!” [1]

Fiber also has the characteristic of being symmetrical, meaning it offers the same download and upload speeds.  This can be crucial for business that require frequent file transfers or data backup.  Speed and symmetry on a copper cable connection depends on the length of the copper line, number of users on net, type of applications, amount of data traffic and technology used. Although it can feature high download speeds, the upload speeds in reality tend to be far lower.

And while both fiber and copper will experience a loss of signal strength in long cable runs, in distances over 100 meters, fiber will lose only 3% of its signal while copper will experience a 94% loss of signal.  That’s a big difference.

Fiber internet is a highly sustainable, next generation technology with the capacity to meet the high bandwidth demands of an ever increasing number of connected devices.  Delivered over a dedicated line, fiber provides consistent throughput even during high-traffic periods of the day.  It also has the characteristic of being symmetrical, meaning it offers the same download and upload speeds.  This can be crucial for businesses that require frequent file transfers or data backup.  Furthermore, multiple users can download or upload, share files and stream simultaneously without affecting overall speed.

Cable internet bandwidth is limited to the size of the physical cable and is shared among several users within a region. This causes a reduction in availability during peak usage periods, which often coincide with traditional work hours.

Fiber is dielectric, which means that no electrical current flows through it.  This makes it resistant to fire and electromagnetic interference (EMI) from lightning, adjacent power lines, and radio signals.[2] Physically, fiber is also more durable.  It can withstand around 100-200 pounds of pressure so it is less likely to be damaged during routine operations or falling debris.  We have seen fiber optic lines still holding with trees laying atop them from a storm, while the cable lines lay broken on the ground.

Unfortunately, because copper cables operate through electrical signals, they can be prone to the effects of EMI listed above and run a higher risk of fire.  They are more susceptible to environmental conditions, including temperature fluctuations, inclement weather, and moisture, all of which can diminish the quality of a connection.  Physically, copper is also a relatively delicate technology.  It can typically “sustain about 25 pounds of pressure without being damaged, which means it can be compromised with relative ease during routine operations in a company’s telecommunications space.”[3]

We live in an era where Internet security is a very real concern.  There’s not a month that goes by where you don’t hear about a cyber security breach on the news.  Thankfully, fiber optic Internet is often touted as a cost-effective way of instantly increasing your Internet security. “Intercepting copper cable can be performed by connecting taps to a line to pick up the electronic signals.  Putting a tap on a fiber-optic internet cable to intercept data transmissions is incredibly difficult. It’s also easy to quickly identify compromised cables, which visibly emit light from transmissions.”[4]
