Review: Invaluable Data/Video over fiber - Can't beat the price. They work great! Many different uses but I send RS485 Dsan Speaker Timer data over fiber from FOH without running and spending time terminating a Cat5 cable...or 2. The SFPs are directional so mark which is transmitter and receiver. Note- SDI Rx is Data Tx and visa-versa. They were probably meant for the Security PTZ community, but I use them in broadcast, sports and events industries.
Review: Works perfectly for my needs - We buy quite a few of these for our business. Good Product Name brand good price no complaints.

### ⭐ COMPLETE FAILURE
*by S***X on May 30, 2025*

Had the largest event we have ever done and needed an HDMI to Fiber Converter set. After doing my research I purchased these as they seemed like a good product. Could not get the signal through. The venues Fiber Optic Tech ran diagnostic's on their system. It was fine, so he ran a diagnostic on the signal we were providing and it too was fine. He then tested this equipment and the transmitter would not talk to the receiver. What an expensive piece of junk. You can bet it's going back!
