Data from comminication device 1 is received at the ODW-730 RS-485 port (as indi-

cated by the TD LED), data bits are retimed according to the preset rate and sent out

on the optical fibre TX1. The next ODW-730 unit receives data at optical fibre RX2 (as

indicated by the RD LED), and data is sent out on the RS-485 port. Data is also repeated

out on TX1 on to the next ODW-730 unit.

Data from some other communication device, for example device 3, is processed in the

same way and sent out on both optical fibres TX1 and TX2. Notice that the Ring Focal

point never repeats incoming data.
