Abstract
A branching unit () for an optical telecommunication link (), the unit comprising a first (), a second () and a third terminal () for termination of conductors of respective branch cables in use, a fourth terminal () for connection to a sea earth () in use, and a circuit () comprising a plurality of relays comprising at least a first, a second and a third relay associated to respectively the first, second and third terminal, the circuit being structured for connecting together two terminals out of the first, second and third terminal and for connecting the remaining terminal to the fourth terminal, depending on a sequence of power feeding at the first, second and third terminals, in use, wherein the circuit () comprises a sea earth circuit () terminated at one end to the fourth terminal and a bidirectional triode thyristor () placed along the sea earth circuit, a driving circuit () being provided for driving the bidirectional triode thyristor so as to trigger the bidirectional triode thyristor in a conduction state only upon complete switch-over of one relay of the group consisting in the first, second and third relay.
