OPTION
2， FEC switch
0：Turn off FEC
1：Turn on FEC（default）
-------------------------------------------------
1, 0 transmission power (approximation)
00： 20dBm(default)
01： 17dBm
10： 14dBm
11： 11dBm
l
After turn off FEC, the actual data transmission
rate increases while anti-interference ability
decreases. Also the transmission distance is
relatively short.
l
Both communication parties must keep on the
same pages about turn-on or turn-off FEC.
--------------------------------------------------------
l
The external power must make sure the ability
of current output more than 200mA and
ensure the power supply ripple within 100mV.
l
Low power transmission is not recommended
due to its low power supply efficiency.
