EtherCAT segment length

I am designing a system with a fair number of basic input and output cards spread over a large area, so am foreseeing decentralized stations. From master to stations, medium length is around 150 meters, with longest one just over 200 meters. Can EtherCAT use repeaters/switches to extend segment length?

Perhaps optic fiber communication could be a simple solution instead of repeaters?

Ethercat: every slave is a repeater (switch).
