It was supposed to work before but because of the issue I faced, I made an assumption. I was wrong, but later tests I ran made me re-evaluate. Actually, your Optical Transceiver Module allows me to support alternatives that were not available previously. I do not know why it was not working initially. But I'm all to happy to have it all working now.
