Looking for a Fast LED

Hi, all

I am looking a fast LED for optical communication, the data rate is 50 Mbps.

So far, the fastest one I can see is SFH4501 with the rise/fall time of 10 ns.

So, my question is 1, can this LED be used for 50Mbps communication?
2, is there some faster LED exists?

LEDs are suitable primarily for local-area-network applications with bit rates of 10-100 Mbit/s and transmission distances of a few kilometers
HFBR-1116T Transmitter
HFBR-2116T Receiver
The HFBR-1116/-2116 series of
data links are high-performance,
cost-efficient, transmitter and
receiver modules for serial
optical data communication
applications specified at 155 MBd
for ATM UNI applications.

WOW, Thanks, The spped is Ok, however, do you know some near infrared LED which works on 850 nm around?
