1. A downhole completion system, comprising:
an upper completion stage comprising a stinger and a first communication line connector;
a lower completion stage comprising a receptacle and a second communication line connector, the stinger configured to engage the receptacle and the first communication line connector configured to couple to the second communication line connector; and
a debris prevention architecture configured to protect the first and/or second communication line connectors from debris,
wherein the debris prevention architecture comprises a flushing system configured to flush at least one of the first communication line connector and the second communication line connector with clean flushing fluid during both a mating operation of the first and second communication line connectors and a demating operation of the first and second communication line connectors; and
a first plunger;
a first plunger chamber, the first plunger configured to move relatively into and out of the first plunger chamber;
a second plunger;
a second plunger chamber, the second plunger configured to move relatively into and out of the second plunger chamber;
wherein during a mating operation of the first and second communication line connectors, movement of the first plunger relatively into the first plunger chamber releases a volume of fluid to flush the second communication line connector; and
wherein during a demating operation of the first and second communication line connectors, movement of the second plunger relatively into the second plunger chamber releases a volume of fluid to flush the second communication line connector.
