Dark Fibre Explained

Posted by: Amira Bird

September 15, 2023

If you’re looking for a high-speed, dedicated, and secure internet connection for your business, then you’ve probably heard of dark fibre. But what exactly is dark fibre, and how does it work?

In this blog post, we’ll explain everything you need to know about dark fibre, including: 

  • what it is, 
  • how it works, 
  • the benefits of using it, and 
  • how dark fibre can help businesses. 

 

What is Dark Fibre? 

Dark fibre is unused fibre optic cable that is not yet connected to any network. It is often available for lease to businesses and organisations that need high-speed, dedicated internet. 

Dark fibre is a valuable asset for businesses that need to transmit large amounts of data quickly and securely. It can also be used to create private networks that are not accessible to the public internet.

What is dark fibre?

 

Benefits of Using Dark Fibre 

There are many benefits to using dark fibre including: 

High-speed connectivity 

Dark fibre can provide speeds of up to 100 Gbps, which is much faster than traditional copper-based internet connections. 

Dedicated bandwidth 

Dark fibre provides dedicated bandwidth, which means that you will not have to share your connection with other users. This can be important for businesses that need to transmit large amounts of data or that require a high level of reliability. 

Security 

Dark fibre is a more secure option than traditional internet connections. Because it is not connected to the public internet, it is less susceptible to hacking and other security threats. 

Scalability 

Dark fibre is scalable, which means that you can easily increase your bandwidth as your needs grow.

 

 

Drawbacks of Using Dark Fibre 

If you are considering using dark fibre, you should weigh the benefits and drawbacks carefully. While there are a few drawbacks for dark fibre networks, engaging with an ICT company for your dark fibre means that you can mitigate most of these. 

Cost 

Dark fibre can be expensive to lease. 

Complexity 

Dark fibre can be complex to install and manage. 

Availability 

Dark fibre may not be available in all areas. 

 

How Does Dark Fibre Work? 

Dark fibre works by using the same technology as traditional fibre optic cable, but it is not connected to any network. This means that the data that travels over dark fibre is not shared with anyone else. 

Dark fibre is typically leased in pairs, one for each direction of transmission. The two fibres are connected at each end by a device called an optical coupler. The optical coupler allows the data to be transferred from one fibre to the other. 

Dark fibre can be used to create a variety of networks, including point-to-point networks, mesh networks, and ring networks. Point-to-point networks connect two points, such as two buildings or two data centres. Mesh networks connect multiple points, such as a city or a region. Ring networks provide redundancy, so that if one link in the ring fails, the data can still be transmitted. 

Dark fibre is a valuable asset for businesses that need high-speed, dedicated internet connectivity. It is also a good choice for businesses that need to create a secure network. 

 

How Dark Fibre Can Help Businesses 

Dark fibre is a valuable asset for businesses that need high-speed, dedicated internet connectivity. It can also be used to create private networks and to support a variety of other applications. If you are looking for a secure and reliable way to connect your business, then dark fibre may be a good option for you. 

While we have already covered some more general benefits of dark fibre, here are some additional benefits that dark fibre can offer for businesses. 

Reduced latency 

Dark fibre can provide lower latency than traditional internet connections. This is important for businesses that need to transmit real-time data, such as financial trading data or video conferencing. 

Improved uptime 

Dark fibre is less susceptible to outages than traditional internet connections. This is because dark fibre is not connected to the public internet, which is more vulnerable to disruptions. 

Greater flexibility 

Dark fibre gives businesses more flexibility in how they use their network. Businesses can use dark fibre to create custom networks that meet their specific needs. 

Why Dark Fibre is the ultimate internet solution
