We need to run fiber to multiple floors and hook in to an ethernet device on each floor.

Would we daisy chain the fiber to each floor and put one fiber converter on each floor or would I need other parts to make this work?

I've seen something similar but they used a fiber converter AND a fiber switch? (fiber with 8 ethernet ports) on each floor, which seems to be unnessesary.

I take it you are referring to a copper interface when you say ethernet, as ethernet is designed for both copper and fiber (and hell can be encapsulated over many other media as well, but i digress).

If your setup looks something like this:

[switch with copper interface]======================[other switch with copper interface]

and the cabling is fiber, then yep, you'll need media convertors on both ends. Also make sure that the plug on both ends is compatible with the connector on the media convertor as well (SC, ST, etc)

yes I mean copper on one end. And this would be for MANY floors in a large building. We have a device that uses an rj-45 ehternet connection and we'll be using several of these devices that need to communicate with each other. If I run fiber to each floor would I just daisychain it between floors?

Is there going to be a device on each floor? if so, does it have more than one port? What sort of device is it? In order to simply daisy chain the devices, they'd need to have more than one ethernet interface, and have the capability to bridge between the two, but it's not a good idea to make the end device functionally be part of the infrastructure.

Ideally the devices should plug into a switch, and the switches should be connected by fiber at each floor.
