Brief Introduction
The Vchung OSFP 2x400G 2FR4 transceiver module is an 800Gb/s 2x400Gb/s Twin-port OSFP, 2xFR4 single mode, Multiplexed, 8-channel transceiver using two, 2-fiber, LC Duplex optical connectors each carrying 4-channels of 100G-PAM4. The dual Far Reach 8-channel (2xFR4) design uses 100G-PAM4 electrical and optical modulation based on the CWDM4 serial, multiplexed 1310nm wavelength grid. It is qualified for use in InfiniBand NDR end-to-end systems.
It is the ideal solution for supercomputing, seamlessly integrating into computing and storage infrastructure to ensure efficient high-performance interconnectivity. Used in Quantum-2 air-cooled switches.

 | Optical 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. |
