Brief Introduction

The Vchung OSFP transceiver module is designed for use in 400 Gigabit Ethernet links over 2km single mode fiber with FEC. The module has 8 independent electrical input/output channels operating at 53.125Gbps per channel. The integrated GearBox in module converts the 8 channels of 53.125Gbps (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 106.25Gbps (PAM4) operation for an aggregate data rate of 400Gbp/s. The optical side of transceiver consists of 4 independent channels on CWDM4 1271/1291/1311/1331nm center wavelength. The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and compliant with OSFP MSA.

OSFP112-400G-FR4 400G OSFP FR4 Flat Top PAM4 1310nm Duplex LC 2km 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.
