What do I need to replace a fiber optic modem (converting the fiber cable to a normal ethernet cable?)

Are any of you guys familiar with fiber optic internet? That's what I'm using, but I'm looking to replace the modem my ISP gave me.

Well, I kinda already have done that. You see, the stock modem was kinda crappy, but I discovered that there was a little removable panel on the modem where the fiber optic cable connects to it. There, I discovered there was a little ethernet cable linking this part to the rest of the modem. I disconnected this cable from the modem, plugged in my own modem router and BAM! I was able to use my fiber internet with my own modem.

This does the job, but keeping the old modem around just to convert the fiber cable to an ethernet cable is kinda bulky, so I'd like to replace it with something more compact. There's clearly some gizmo inside the modem that does this conversion, so I think that's what I need to buy.

I found this thing on Amazon (http://amzn.asia/gMcwKWa) and I think this might be what I need? There seems to be three different types though, so I'm not sure which one I would need.

The MC220L uses a connector that looks nothing like the connector my fiber cable uses, so I think that's right out. There remaining two both have the same looking connector, which I think supports SC connectors, which appears to be the kind of connector I have, based on shape and that SC was created by NTT who is my line provider.

This leaves me with a choice of multi mode or single mode. As I understand it, multi mode is only used for short distances, so being that my cable is for internet, I would guess that mine is single mode cable, right? So I think the MC210CS is the model I need?

So the final question is, which port would I plug my fiber cable into? I think "RX" is for receiving, so it would be this port, right?

It is surprising you could make that work most the fiber boxes are much more complex because they can carry cable tv also.

Unfortunately there is no way to really know for sure. There are actually many different optical frequencies rather than just single and multi mode. The fiber itself maybe single mode but you can connect lots of different optics to it.

Many of these systems are very proprietary and you can not generally even buy the optics. For example FIOS use a single fiber (not a pair just 1 stand of fiber). It receives signal on 2 different frequencies lasers and transmits on a third. So on the same physical media they are using 3 different optics and sending and receiving at the same time all on a single piece of glass.
