1. An apparatus for managing an optical subsea communications system, comprising:
a plurality of fiber interface modules (FIM), wherein a given FIM comprises:
a receive part, comprising a line monitoring equipment (LME) RX line, line terminating equipment (LTE) RX line, command response equipment (CRE) RX line, a LME RX port, connected to the LME RX line, a LTE RX port, connected to the LTE RX line, and a CRE RX port, connected to the CRE RX line; and
a transmit part, the transmit part comprising a LME TX line, LTE TX line, and CRE TX line, a LME TX port, connected to the LME TX line, a LTE TX port, connected to the LTE TX line, and a CRE TX port, connected to the CRE TX line,
wherein the transmit part further comprises two normally closed switches, wherein a first switch of the two normally closed switches is coupled on a first side to the LME TX port, and is coupled on a second side to a first side of a second switch of the two normally closed switches,
and wherein the second switch of the two normally closed switches is coupled on a second side to the LTE TX port.
