profinet tru optical fiber

Juan de Via Posts: 28 Rating: (0)	I need help , advice . for a project using S7-1500 and 4 remore station with ET200 IO profinet comm. the distance between the stations 500 mtr. a total distance of 2 Km. right now exist a couple optic fiber (type:single mode) all the way, that is use for video true ethernet. is it possible to use the same fiber to profinet at the same time? if yes , I suppose that is needed to use some split device. can you tell me what type? also I understand that is needed to use an optical sender and receiver at each station. what will be appropriate for fiber type single mode? thank you for your help Juan de Via

Have a look at Siemens Scalance X100 unmanaged switches with media converter (from copper RJ45 to multimode or single mode fiber): http://w3.siemens.com/mcms/industrial-communication/en/ie/industrial-ethernet-switches-media-converters/Pages/scalance-x-100-unmanaged.aspx Note that most industrial switch manufacturers offer similar media conversion, so look at their catalogs also: Red Lion, Belden, NetGear, Moxa... We have never attempted to multiplex Video signals with Ethernet communications on a single F.O. cable, mainly because video requires so much bandwidth we always preferred using separate channels in our projects. And F.O. cable is cheap enough now to make this requirement unnecessary (signal splitters would probably cost as much as a new cable and introduces another point of failure in the system). But you can always look for special splitters and multiplexers...
