Multidrop via fibre optical network

The data is transferred via the fibre optic network to the serial ports of all units. If
ODW-622 is connected to two optical fibre links (mid unit) converted data will be trans-
mitted in both directions, via both CH 1 and CH 2. With only one optical fibre link (end
unit) converted data will be transmitted in one direction, via CH 1 only. Data received
from one ODW-622 optical fibre port will be repeated through the other optical fibre
port and it will also convert the frame to serial data.
