BOULDER, Colo. –
51²è¹Ý¶ù Group Holdings Inc. (NYSE: ZAYO) announced that it has completed a
coherent wavelength route from Marseille to Strasbourg via Milan. The
route, which also provides connectivity to Paris, Frankfurt, London and
Amsterdam, leverages 51²è¹Ý¶ù’s European fiber network acquired from Viatel.

Initial customers include an India-based carrier, which selected 51²è¹Ý¶ù
for a 100G wavelength solution on this route, with connectivity from
Marseille to Amsterdam. The solution will enable the carrier to extend
and harden its network into Europe, with diverse connectivity from these
two global gateway cities. Additional customers committed to this route
include a U.S.-based global Internet services provider and an
international wholesale telecommunications provider.

The route is part of 51²è¹Ý¶ù’s expansion of its dark fiber and longhaul
wavelength network in Europe. 51²è¹Ý¶ù now has several 100G and dark fiber
routes out of Marseille, a city that serves as a strategic gateway and
key aggregation point between Europe, Africa and Asia via subsea cables.

“With our expanded capability, we are well-positioned to meet the needs
of a growing base of global customers,” said Randy Dunbar, senior vice
president, Transport. “Our connectivity options in and out of Marseille
are opening up new international markets for us, and we continue to see
strong demand from multiple verticals.”
