Metroweb (formerly Citytel), also known as Metroweb Milano, was a fiber-optic network operator based in Milan, Italy. It was a subsidiary of Metroweb Italia S.p.A.
Founded in 1997, Metroweb was known for its fiber-optic cabling. Historically, it wired Milan, allowing Fastweb's FTTH services and a wide range of dark fiber to operators and companies of all kinds.
Operators use a GPON network by renting Metrobit "monofiber", a single fiber of the single-mode type that allows full-duplex at gigabit speeds.
In 2017 it was merged into Enel Open Fiber.
