They are standard jumper wires but have the added benefit of having connector ends, so you can make any connection to a breadboard that you need to.

The wee prong of one end of each wire fit into a test point hole on the router, and the wee socket on the other end fit a prong on the FTDI. No need to solder as long as you kept enough tension on the wire to keep a good contact on the test point hole.
