Which parameter in the datasheet of the LED defines the turn on time and turn off time?
What kind of LEDs are used for high speed switching applications? Thank you

Normally that will be rise time or fall time. If not listed, presume the LED to be poor at data transmission.

I use laser LEDs to transmit data at high speed but my version of high speed is only about 600 Mbps whereas a lot of laser LEDs can go well into the Gbps. The best standard LED I reviewed was good for about 100 Mbps. It was an Osram SFH4750 (infra red).
