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.

I finally decide to give LINK-PP Ethernet port a try, since they are not as expensive as an original module. The result makes me very satisfied. They work well with very low insertion loss on our equipment, and the connection is also very firm.
