Is it possible to share one port from the back of my router via a splitter?

No, Ethernet does not work this way. You cannot use a splitter of that sort to provide two Ethernet connections from one. The device you've linked there isn't really for Ethernet, even though it's using RJ45 -- it's intended for certain kinds of telephony devices. If you were to use that on an Ethernet network, the havoc created would be quite large. Duplicate packets, ARP/MAC confusion, packet loss, and quite possibly not even reliable link (has to do with the level of voltage needed to establish link; splitters often half this).

Your router should have multiple LAN ports on the back of it (I'm assuming at least 4); if those are all full and you need more, as @lancethepants said, you need a switch. A simple 4-port switch will do the trick (if too expensive, look for other brands, ex. D-Link, Linksys, etc.).
 
You can't use a regular splitter, but there are special ethernet splitter/combiners that you can use, like this one:

http://www.amazon.com/C2G-37049-Network-Splitter-Combiner/dp/B008GTIUKY

They use the normally unused extra pairs in the ethernet cable. Usually a switch will make more sense, though.

You should read the description of the product you are posting:
*Please Note: Use of this product requires two available Ethernet ports on a network switch. The pair of RJ-45 Combiner kit must be used together for each installation, one on each end of the cable run, for proper operation.

This wouldn't help the OP, there is no way to turn one switch port into two.
