Connectivity services

Datum Dark Fibre offers a layer one connection with the ability to completely control the network environment. Anything and everything that passes down the fibre is controlled by the operator, whose own network team light and manage the connection.

Datum Dedicated Fibre is a solution that provides the user with all the benefits of Dark Fibre, without needing a specialist networking team in place to manage it. Dedicated Fibre offers a layer one connection with the control you need, while outsourcing the management of that connection to technical experts.

Datum Wavelength enables you to lease a Wavelength in a managed fibre network giving you the security, capability, uncontested nature and speed of a single leased dark fibre, at a greatly reduced cost and infrastructure requirement.

Datum IP transit allows your traffic to take full advantage of our triple-node resilient Tier 1 carrier connections to access the public internet. Datum IP Transit service runs over Tier 1, IPv6 enabled, optical IP networks.


Datum Multiprotocol Label Switching (MPLS) is a scalable network management solution. Data packets are assigned labels and find the quickest route at the time. This allows us to create efficient, private end-to-end circuits across our network for our clients.

Datum multi-service leased line is more than a connection to the internet. Datum can link you directly with Public Cloud services, backup facilities, co-location, or any of our on-net partners’ hosted services, such as virtual desktop or VOIP, all with guaranteed quality of service.

Datum Wireless WAN solutions avoid the costly process of introducing cables into a building, as a work-around for difficult to reach locations, or as a cost effective backup.

Datum Office Connect enables you to store your data and systems centrally in a local data centre, giving you the security of cloud backup combined with the peace of mind and serviceability of being able to touch it.

Datum Cloud Connect provides client connects to our network at any POP or on-net data centre.
