Transmission distance
#1: The transmission distance can be increased by using the mode conditioning
patch code. However, the maximum distance for transmission is 2 km, and that
distance depends on transmission loss. For 2 km transmission, the transmission
loss must be no more than 10 dB.

#1: Some kinds of multimode fiber optic might increase the BER (bit error rate)
when used with 1000BASE-LX. In this case, proper communication can be
established by using the mode-conditioning patch code.
