Context Before
This gives rise to the engineering problem of ensuring that a clean signal can be received at either end of the wire because two signals sent in opposite directions over the same copper wire will superpose to form a composite signal that is different from the intended transmitting signal.
Evidence
In optics, bidirectional interconnect can be achieved by integrating an optical circulator to a transceiver.
Context After
The circulator works by routing the inbound and outbound signal onto separate paths, ensuring no overlaps between both at the photodiode receiver. Bidirectional interconnect is, however, much trickier in the copper domain.
② Atomic Claim
在 optics 中，可以透過把 optical circulator 整合進 transceiver 來實作 bidirectional interconnect。
