Copper Vs Fiber Optic Cable – Which is best for networking?

When you design a network, the type of networking cables matters alot. There are two types of cabling: Copper & fiber optic cable. Each cable has its own distinct advantages depending on speed, distance, and budget requirements. How fast, reliably, and easily the network can grow will depend on the choice you make.

In fiber optic cables, data is transferred through light. On the other hand, in copper wire, electricity plays a role. This blog compares copper vs fiber optic cable. Also, it helps you to choose the best one for your network.

A Quick Overview of Cable Types

Copper lines and fiber optic wires are used by most networks. Each type is best for a different job.

Fiber Optic Cable

These cables have one or more thin glass strands equal to the thickness of a human hair. Through internal reflection, a light signal travels the fiber's length and transmits the information efficiently and quickly. In fiber optic lines, data is sent by light moving through these thin strands of glass or plastic. Coverings, cladding, and sometimes Kevlar are put around the core to make it stronger.

Available types of fiber optic cables:

• Single-mode fiber: In this type of fiber, signals travel long distances with little loss.  This cable type is suitable for large networks and phone calls.

• Multimode fiber: This fiber type is suitable for short-distance links in LANs and data centers. It costs less than single-mode, but there is more signal loss.

• Indoor fiber cable: This type of cable is safe to use inside buildings and has covers that won't catch fire.

Single-mode vs Multimode: 

The center of single-mode fiber is small and only sends light; data can be sent over long distances with little signal loss. It can join very quickly, which makes it great for public schools, long-distance links, and business networks. The bigger core of multimode fiber allows it to send more than one light signal at the same time. This makes it good for short distances like offices, data centers, and local area networks. In general, multimodal is less expensive, but messages weaken more when sent over long distances.

There are many advantages of Fiber Optical Cable:

·         Control high bandwidths (up to 400 Gbps or more)

·         Low signal loss over a large area

·         Electromagnetic interference (EMI) Resistance

·         Safe due to Difficulty in tapping

·         Ability to survive harsh circumstances

·         Ready for the coming 5G, IoT, and terabit networks

Fiber optic wire makes sure that the network can meet new digital needs as they grow.

Copper Cable

Copper wires use electrical signals to send data. Also, installing them is simpler and less expensive, especially for small networks.

Available kinds of Copper Cables:

• Cat5e: One gigabit per second over 100 meters

• Cat6: Over 55 meters, and up to 10 Gbps

• Cat6a: Better speed for 10 Gbps beyond 100 meters

• Cat7: Shielded, high-speed cable for demanding networks

• Shielded/Unshielded: messages don't get mixed up in noisy environments

These are the Advantages of Copper Cable:

·         It's easier to set up and handle

·         costs less to set up at first

·         works well for short distances and old systems

Copper works well in homes and small offices that don't need a lot of speed.

Future-Proofing, Upgrades & Trends

There are more changes than ever in the needs for networks today. More and more people are using 5G, IoT devices, cloud computing, and 400 Gbps to terabit networks. This makes it more important to have fast and stable networks. Companies need cables that can handle more data, faster speeds, and links that stay strong in smart settings these days.

Fiber optic technology is leading this transformation. New next-generation networks can grow with its help, and it gives them the speed, scalability and bandwidth they need. It is possible to send very fast data over long distances with single-mode fiber. On the other hand, multimode fiber works really well in places like data centers where speed is important over short distances. You can quickly improve or change fiber networks without having to repair the cables that are already in place, which makes them a good buy.

Copper is a cheap choice for home networks, small businesses, and other places where the distances between devices are short. It is easy to install and works effectively in places where high speeds are not necessary. Moreover, it also works well with old installed equipment. This suggests that adding all fiber may not be worth it.

Security & Environment-Specific Factors

When you choose between copper vs fiber optic cable, security and environmental conditions are important factors. There are different ways that each one works when chemicals, the surroundings, or both stress it.

Wires made of fiber optics are safer than other kinds. It works great for secret networks because it's hard to tap without getting caught. Electrical and magnetic fields (EMI) can't pass through fiber, so it doesn't pose as many fire or electricity risks. Because of how it's built, it can safely work outside, underwater, and in places with a lot of moisture.

But there are some problems with copper wire.  It's easy to tap if you don't protect it properly, and EMI can mess up the signal. Things can rust over time because of changes in temperature and moisture. This makes them less helpful.

Fiber is still the better choice for sensitive or large-scale systems that need to last a long time and be safe. Copper is safe for controlled indoor setups.

Making the Right Choice: Fiber Optic vs Copper Cables

Considerations of cost: 

Traditionally, copper cabling is considered as a default option because it is affordable. The cables themselves are less expensive than fiber, and the installation is usually simpler. Many networking technicians use copper cabling as the equipment required for copper cabling is common and inexpensive. 

However, the cost of ownership can be expensive. Copper installations usually need supporting infrastructure such as intermediate wiring closets, repeaters, and power supplies because of their distance limitations. Due to this, copper's cost increases in large installations or where distance is an issue. 

But Fiber Optic Cables have dropped in cost in a major way recently. Although still more costly to install initially than copper, fiber networks will cost cheaper in the long term. You don't require as many repeaters. Also, the installation will occupy less space, which means less real estate and maintenance expenses. 

In countries such as Pakistan, fiber optic cable is becoming more readily available, with ISPs and local providers spending large sums of money on fiber infrastructure. 

Speed and Bandwidth  

Bandwidth regulates how much data a cable can carry over a given period. Here's where fiber optics is an advantage. 

Fiber Optic Cables can handle large amounts of data. Single-mode fiber can have data rates of up to 400 Gbps or higher. Also, the theoretical research shows potential data in the Terabits per second range. Even multimode fiber supports up to 10 Gbps over hundreds of meters.

On the other hand, copper cables are more restricted. For instance: 

• Cat5e: 100 meters at 1 Gbps 

• Cat6: Only about 55 meters, but up to 10 Gbps 

• Cat6a and Cat7: greater safety at 10 Gbps over 100 meters 

The need for bandwidth is only increasing in settings that need high performance, like data centers or enterprise networks. Fiber's capabilities make it the clear winner here. 

Transmission Distance 

Transmission range plays a significant role in the argument between optic vs. copper cables. 

Long distances cause signal attenuation, or weakening, in copper cables. As a result, a typical Ethernet copper connection requires a signal booster or repeater after 100 meters. 

On the other hand, fiber optic connections can carry data over far longer distances without degrading: 

• Fiber with many modes: 10 Gbps up to 550 meters 

• Up to 40 kilometers of single-mode fiber (or more with amplifiers).  

For buildings, campuses, or even underwater transcontinental networks, fiber is the preferred solution.
