1. An open cable interface comprising:
a first optical path configured to connect to a terrestrial cable of an optical network to a submarine cable, wherein the first optical path is configured to provide first communication signals from the optical network to the submarine cable; and
a second optical path configured to connect the submarine cable to the terrestrial cable of the optical network, wherein the second optical path is configured to provide second communication signals from the submarine cable to the optical network, wherein the first and second communication signals are within a first frequency band; and
a first filter positioned on the first optical path and configured to:
pass the first communication signals; and
filter out secondary signals from the terrestrial cable such that the secondary signals are prevented from reaching the submarine cable, wherein the secondary signals are within a second frequency band that does not overlap with the first frequency band.
