A Brief History of Optical Networks and How 100G is Changing the Game – The Next Generation in Data Center Technology

Introduction: What is an Optical Network?

A 100G optical network is a network that operates on the 100 gigabit Ethernet standard. It is often used to connect data centers, which are at the heart of today’s internet.

In order to understand what a 100G optical network is and how it works, we first need to understand its predecessors. The first networks were made up of copper cables and had bandwidth speeds of 10 megabytes per second (Mbps). This was followed by networks made from coaxial cables that could transmit data at 50 Mbps. Then in the 1990s, fiber optic networks came into use, which were capable of transmitting data at speeds up to 1 gigabit per second (Gbps).

The 100G optical network is the next evolution of the internet. It will allow for faster data transmission, higher bandwidth, and more efficient use of bandwidth. The need for a 100G network is driven by the increase in internet traffic and data centers. The internet traffic has increased from 1 exabyte per month in 2010 to 3 exabytes per month in 2016. And there are about 250 million people using the internet on a daily basis.

How Does a Data Center Use an Optic Network vs. Copper Cable?

A data center can use both copper cable and fiber optic cable. In the past, copper cables were used because they were much cheaper than fiber optic cables. Fiber optic cables are more expensive because they are made of glass, but they have many benefits over copper cables.

Copper is an older technology and it has a lot of limitations, such as slower speeds, less bandwidth, and the inability to use for long distances. Fiber optic cable is a newer technology that has a lot of benefits over copper cable. It’s faster and has more bandwidth than copper cable. It also doesn’t have the same limitation as copper cable when it comes to distance because you can use fiber optic cables at much greater lengths than you could with copper wire.

A copper cable is made up of metal wires that are insulated by plastic or rubber and wrapped in insulation material, such as polyethylene or PVC. It is used for transmitting electrical signals from one place to another. Copper cables have higher bandwidths than optic networks and lower latency rates, but they can only be used for short distances before the signal degrades.

What are the Advantages & Disadvantages of Using a Transparent Optical Network in a Data Centre?

The advantages of using a transparent optical network in a data center are numerous. The most obvious one is the speed that it provides. Optical networks are capable of providing speeds up to 100 gigabits per second, whereas traditional copper networks can only provide speeds up to 10 gigabits per second. This means that an organization can have more than 10 times the bandwidth available to them with a transparent optical network.

Another advantage is that these networks are more secure than traditional copper networks, as they cannot be tapped into and monitored by unauthorized personnel. They also have lower latency rates and the ability to use different wavelengths for different applications, which makes them perfect for high-speed data transfers and video streaming applications.


When it comes to data centers, there are a few key components that need to be considered. First and foremost, there is the server. The server is where all of the data processing happens and where all of the information lives. Optical modules are also important, choosing a suitable optical module can make the transmission link more stable and reduce the loss in optical transmission. A 100GBASE-SR4 optical module allows data centers to building 100Gbps Ethernet.
