Brief Introduction
The Vchung OSFP 2x400G LR4 transceiver modules are designed for 800G Gigabit Ethernet links over 10km of single-mode fiber. The module has 8 independent channels of electrical input/output, each operating at up to 106.25Gbps. This transceiver consists of two transmitter/receiver units, with each operating on a set of 4 wavelengths on the ITU G.694.2 CWDM grid near 1300nm. The module’s transmitter path contains a bidirectional PAM4 re-timer ASIC integrating an 8-channel modulator driver, 8 externally modulated lasers, and two optical multiplexers. On the receiver path, two optical demultiplexers are coupled to eight photodiodes and two 4-channel TIA arrays, as well as a PAM4 re-timer. The electrical interface of the module complies with the 800GAUI-8 interface defined by IEEE 802.3ck and complies with OSFP MSA.

 | 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. |
