Optical Fibre 12G SFP module question

As you look head-on at the SFP module in the Optical Fibre 12G, which side is the transmitting laser? Left or right? I have seen conflicting diagrams online, but most show the left (head-on view) as TX.

The SFP should have little arrows (triangles) above the LC ports indicating the direction.

Thank you. Just took one out and they are there.

Someone also suggested to take a photo with a mobile phone, which I did, and you can actually see the red dot of the laser. Which is also handy to confirm that you actually have a working transmitting laser.
