Zayo Group Holdings (NYSE: ZAYO) says it will construct a dark fiber ring in the Montreal metro area for a global cloud provider Zayo didn't further identify. The 60-km dark fiber ring will run along the South Shore section of the city, which Zayo says is an emerging technology and data center hub.

The ring will connect multiple data centers for the client. Zayo asserts it won the contract due to "its leading fiber network in Canada, deep experience in building high-performance fiber network, and flexibility in planning for the customer's continued growth."

Zayo also will use the additional fiber-optic network cabling to expand its footprint into several metro municipalities in the Montreal area. The company gained fiber-optic network infrastructure in the city as part of its acquisition of Allstream in 2015 (see "Zayo to buy Allstream for Canadian expansion").
