QSFP-DD-800G-DR8  800GBASE-DR8 PAM4 1310nm 500m DOM MPO-16/APC SMF TransceiversOptical transceivers port(LC)

For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors).
Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals.
