Context Before
A circulator cannot be used as copper cables are linear transmission lines, which means that the inbound and outbound signals will be summed at the receiver through superposition. The receiver at each end of the copper wire therefore needs a mechanism to separate the local TX from the local RX.
Evidence
The solution to this problem is the use of a hybrid at each end of the wire.
Context After
Without a hybrid, there will be self-interference at the local RX because both the local TX and local RX are being transmitted along the same wire:
