Claim 0:
1. An optronic transceiver module capable of implementing an optical bidirectional communication of the point to point type via at least one main optical fibre the optronic transceiver module comprising:
a first optical module for supervising an uplink signal received via the main optical fibre delivering a first supervision result;
a first optical module for switching the bidirectional communication via the main optical fibre to a bidirectional communication via a backup optical fibre, and vice versa, the first optical switching module being controlled by the first optical supervision module depending on the first supervision result delivered;
also comprising a second optical module for supervising an uplink signal received via the backup optical fibre delivering a second supervision result and controlling the first optical switching module; and
wherein the first, respectively the second, optical supervision module comprises:

a first, respectively second, sampling uplink optical coupler capable of splitting at least one uplink optical signal received via the main optical fibre, respectively the backup optical fibre, into two optical signal split according to a predetermined power ratio for the split optical signals, the first, respectively second, sampling uplink optical coupler delivering a first, respectively second, low-power signal and a first, respectively second, high-power signal; and
at least one first, respectively second, power measurement photodiode delivering a first, respectively second, power measurement associated with a first, respectively second, low-power signal.
