Brief Introduction

The Vchung 400GBASE-LR4  supports link lengths of up to 10km SMF with duplex LC connector. It is compatible to IEEE 802.3cu for 400GBASE-LR4-6km requirements but extends the reach to 10km, is compliant to100G Lambda MSA group 400G-LR4 requirements, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.FEC is performed on the host platform.

QSFP-DD-400G-LR4 400G QSFP-DD LR4 PAM4 CWDM4 10km LC 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.
