400G-FR4 / 400G-LR4: These transceivers use duplex LC connectors. The FR4 and LR4 transceivers use WDM (wavelength division multiplexing) to allow the use of two fibers instead of eight.

400G FR4 LR4

400G-DR4 / 400G-XDR4 / 400G-PLR4: These transceivers use a MPO-12 connector since the DR4 standard splits the 400Gbps signal into four parallel 100Gbps channels.

400G DR4

400G-BIDI (400G-SRBD): Bi-directional transceivers typically use LC connectors as they work by simultaneously transmitting and receiving data over one fiber.

400G BIDI

400G-SR8: This transceiver uses MPO-16 connectors, as the SR8 standard splits the 400Gbps signal into eight parallel 50Gbps channels.

400G SR8

400G-2FR4: This transceiver would typically use duplex LC connectors. It’s a two-lane 400GBASE-FR4 variant that uses two wavelengths on a single fiber, enabling duplex LC operation.
