You’ll have heard of Dark Fibre, but just who ‘owns’ Dark Fibre and is it something you should invest in?
Dark Fibre refers to unlit or ‘dark’ fibre optic cables that are leased from network service providers and carriers. Businesses use this Dark Fibre to create their own private optical network rather than leasing fixed bandwidth and enables businesses to control their own network.
One of the biggest downsides of Dark Fibre is the cost – not only to lease the fibre, but to attach the equipment and each end and for the in-house expertise required to run the network. However, despite that there are many advantages to Dark Fibre.
As Dark Fibre is unmanaged and privately leased, this mean the network can be configured in the way the business who has leased the fibre chooses, whether this is in a ring, point-to-point (P2P) or point-to-multipoint (P2MP). They also have the ability to then take advantage of technology such as Dense Wavelength Division Multiplexing (DWDM) to get the very most out of the fibre.
Dark Fibre is also a dedicated connection, the capacity is not shared with anyone else so businesses can sure of no contention, as well as enabling the ability to easily scale bandwidth up and down as needed. Dark Fibre is best suited to those businesses who require high-speed and high-capacity and can offer a future-proof option for businesses with the need to scale up or down as needed.
