Brief Introduction

The Vchung 400Gb/s OSFP optical module. It provides increased port density and total system cost savings. The OSFP full-duplex optical module offers 4 independent transmit and receive channels, each capable of 106.25Gb/s operation for an aggregate data rate of 400Gb/s on 100 meters of OM3 multi-mode fiber. An optical fiber cable with an MTP/MPO-12 connector can be plugged into the OSFP SR4 module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for proper channel to channel alignment. Electrical connection is achieved through an OSFP MSA-compliant edge type connector. The central wavelengths of all the 4 parallel lanes are 850nm. It contains an optical MPO-12 connector for the optical interface and a 60-pin connector for the electrical interface. Host FEC is required to support up to 100m OM3 multi-mode fiber transmission. The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the OSFP Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.

OSFP112-400G-SR4 400G OSFP SR4 Flat Top PAM4 850nm 30m on OM3/50m on OM4 MTP/MPO-12 Multimode 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.
