#1: Use of mode-conditioning patch cords can extend the transmission distance. However,
the maximum distance for transmission is 2 km, which might result in transmission loss.
For the purpose of transmissions at a 2-km distance, it is required to reduce the
transmission loss to around 10 dB or less.
