Experience complete bandwidth and protocol flexibility - limited only by the type of equipment you connect at each end - with Dark Fibre. This unlit fibre is a Layer 1 physical network service operated between 2 end points and built on a passive network. This means you can:
  • Rapidly and cost-effectively upgrade without any additional carrier costs as your business requirements and technology evolves
  • Run 1Gbps Ethernet, 10Gbps Ethernet, FibreChannel (SAN) or multiple DWDM wavelengths across the service by connecting
  • the corresponding hardware at each end
  • Get access to the improved reliability and significantly lower latency that is available with dedicated glass when compared to traditional managed carrier services.


Almost unlimited bandwidth

Can carry virtually unlimited bandwidth, limited only by the
equipment installed on each end of the service.

ISO 9001 Certified

TPG operates an ISO 9001:2008 certified management system that assures the quality of installation, management
and maintenance.


Very secure data transfers because the fibre is not shared
with other customers.

Complete control of your WAN

Complete bandwidth and network protocol flexibility - upgrade
by changing your hardware and upstream configuration.
