Optical ring configuration

Several mini starcouplers can be cascaded in the ring configuration.
The transmitter channel 1 must be connected with the receiver channel1 in the next
mini starcoupler, and then back to the pc/modem. In this manner a ring configuration
is created, whereby one additional output per mini starcoupler to a protection device
is available
Attention! The data from the pc are mirrored back to the pc or modem.
