MILAN, March 25 (Reuters) - Italy's Prysmian

has agreed to buy U.S. connectivity solutions manufacturer

Channell Commercial Corp for up to $1.15 billion, the world's

largest cable maker said on Tuesday, on the eve of its investor

day.

Prysmian said the deal marked its first acquisition in a

sector that complements its business of digital solution cables,

which includes supporting the expansion of data centres and the

roll-out of 5G technology in the United States and Europe.

The deal's price tag of $950 million could be increased by

up to another $200 million based on Channell achieving certain

financial results this year, Prysmian said.
