I has a solution requirement that involve several tiers connection.  Are you able to test and confirm it can work and keep the signal integration (video quality) across all the layers? 

sources--->VE2812EUT--->VE811R--->1 meter HDMI cable--->VE883Tx--->Singlemode fiber--->VE883Rx--->VM0808HA/VM5808H Matrix switch--->VE883Tx--->Singlemode fiber--->VE883Rx--->monitor 

We test the connection diagram and the installation works. 

Although it works, I have the watch point to pay attention as below.

1. The HDMI cable used end to end in the installation needs to use high quality and no longer than 2M. 

2. The powering sequence for the entire installation has to follow from the source to the final display device as shown on the connection diagram attached.
