The plants are being built as extensions on already existing factories located in Slatina, Romania, and Presov, Slovakia and will be opened in the coming months, the company said in a statement.

Both plants will be the biggest in Europe for their category once they reach full capacity at the beginning of 2017.

The Slatina factory started its manufacturing activity in 1973 with production of energy cables before introducing the first module for the production of optical fiber cables for backbone and access networks in 2009.

After important investments in 2013-2014, the total yearly production capacity for optical cables grew to almost 4,500,000 fkm. With Prysmian’s new investment of EUR22 million, the factory’s production capacity is estimated to reach 8,000,000 fkm, the company said.

Prysmian fiber optic cable factory was built in 2013 in Slatina, in a EUR15 million investment.

Globally, Prysmian has 88 factories and around 19,000 employees in 50 countries.
