Global Voice plans to build metro networks in London, Berlin and Munich after raising €32m (£22.2m) in a bond scheme.
The plans include the commissioning of a next-generation long-haul network through Germany, and the expansion of additional data centre space in Amsterdam and other markets.
The network operator, which trades as euNetworks in Europe, issued the bonds to allow for the investment following increased customer demand.
"This enables us to accelerate investment in key markets where we have already seen strong advanced demand for our expanded service and infrastructure offerings," said Noel Meaney, chief executive at Global Voice.
Meaney added that the uptake of the bond validated the company's performance to date, and that the investments were supported by signed customer agreements in most circumstances.
The convertible bonds raised €32m before expenses, with a five-year maturity and three per cent annual interest rate.
Global Voice owns and operates a high-capacity fibre network in Europe, providing communication infrastructure and services.
The network combines 'long-haul' with 'last-mile' fibre, and Global Voice is used by Europe's largest corporate companies, carriers and service providers.
