The one dipicted in TLC has twin (figure of eight) wires for the 12V DC output - far easier to strip and insert into the camera power connector, than trying to modify a coaxial cable.As we have both said, they are definitely visibly different - so, in that sense, what you have is clearly 'wrong'. However, whether the one depicted in the TLC piccie would any better suit your purpose (in terms of connectors), I have no idea.
That was the basis for my recommendation of it.
