How Fiber Delivers Enterprise-Class Connectivity for Businesses

By Joey Penick, Vice President of Marketing, Lumen

Back in the early days of broadband internet connectivity, all broadband just meant “fast”. Years later, broadband options have diversified. Today, fiber is gaining traction as it outpaces more traditional options in performance and reliability. Learn more in this article about how fiber can take medium-sized business connectivity to the next level.

Before fiber, there were two ‘last mile’ technologies that connected homes and offices to the internet, both sending their signals over copper cable. Digital subscriber line (DSL) technology uses existing telephone cables originally designed just for voice calls. The traditional alternative to DSL is cable internet, which uses the cable TV infrastructure. This is always an asymmetric technology, meaning that it downloads data slower than it uploads.

Fiber is a different story entirely, using tiny strands of glass to transmit data as light. Over the last few decades, fiber has been the communications medium of choice for sending data across vast distances along the internet’s core networks. You’ll find fiber cables under the world’s oceans, carrying data between continents. More recently, it has spread to the last mile, boosting communications to new levels for many former DSL and cable users.

What does fiber mean for small and mid-sized businesses? Here are some key benefits that businesses can expect when they opt for a connection that uses a radically different way to send and receive data.


Better Bandwidth

One of the biggest differences between fiber and copper is its bandwidth. Fiber offers both download and upload bandwidth of up to 1Gbps, while DSL has traditionally offered lower bandwidth. While there are some newer DSL technologies that offer higher rates equaling fiber, they’re designed only for very short distances between the customer and the service provider.

Fast Uploads

Copper users also often face a disparity in download and upload bandwidth. Many (but not all) types of DSL are asymmetric, allowing lots of data to download while capping the amount of data that can upload at one time. Cable connections are almost always asymmetric, with uploads topping out at around 50Mbps. Fiber connectivity on the other hand gives a business the same bandwidth when sending data from their network as when they’re downloading it.

Long-Distance Reliability

It isn’t just network congestion that affects speed and reliability. Copper signals often degrade over distances, affecting service speed, with DSL speeds determined largely by how far the customer site is from the local digital subscriber line access multiplexer (DSLAM). This forces carriers to introduce special equipment in an effort to sustain signal speed, reliability, and quality.

Resilience to Electrical Interference

Fiber’s physical makeup also gives it other reliability benefits. For one thing, its signals are more immune to local environmental conditions. Copper cable uses electricity to conduct data, making it susceptible to interference from power lines, lightning, strong motors, and other sources of strong electrical power. This interference can disrupt the data flow, introducing data communication errors and affecting speed. A critical application that relies on solid network communications could be badly affected by sustained interference such as an electrical storm. Because fiber transmits its data as pulses of light, it isn’t subject to the same interference.

Strong Support for Multimedia Applications

Fiber is an excellent choice for low-latency applications like voice over internet protocol (VoIP) telephony or videoconferencing. Its fast upload bandwidth and long-distance reliability increases bandwidth while keeping communication speeds high. If network congestion causes those packets to stutter, the phone call or video image might degrade, causing problems for people at either end of the connection. That’ll enrage a CEO who just spent thousands on an office videoconferencing system (or a branch manager wondering why her point of sale system is taking so long to process orders).

When it comes to performance and reliability, fiber offers nothing but advantages. And, because it began rolling out several years ago, it’s reaching a tipping point as it becomes more ubiquitous, meaning that more people are enjoying its advantages – leading prices to fall.

Fiber is the future. Expect to see its coverage grow, and for services to take full advantage of this technology.
