Very interesting product. Since you can transmit 40km, the same optical power is received at short lengths, do you use attenuator(s) at the receiver to protect it from high power ?

[@rleoNIU]

Can you use these with the One to many setup on a Gigabit switch with SFP outputs? If I have a standard 4k HDMI over CAT6 input to the Switch, can I use 4 of the CAT6 outputs and 2 SFP units to give 6 screens video? Say 3 of them at 150', one at 250' and two more at about 600'?

I'm confused though. If SFP+ maximum is 10G, but HDMI 2.0a is 18 Gbps, how can it be lossless?

Does this also work if I use a SFP to RJ45 transceiver/adapter?
