The extra charge is in installation fee, but yeah, for 800 USD the cost of 25Gbps transmitter is negligible over letting go of a client needing more than 10Gbps

The extra charge is in installation fee, but yeah, for 800 USD the cost of 25Gbps transmitter is negligible over letting go of a client needing more than 10Gbps, and ready to pay for it. Note, it's not a PON, but real symmetric, point-to-point connection. I once had 250mbps over 1000BaseLX, and it was way more expensive than 500mbps GePON coming after it.
