Brief Introduction
The Vchung 200G QSFP-DD AOC assemblies are designed to support 200G Ethernet and InfiniBand EDR, suitable for data center and HPC (High-Performance Computing) links up to 100m over multi-mode fiber with FEC. The 200G QSFP-DD AOC assemblies are compatible with IEEE 802.3bm 100GBASE-SR4 and support eight electrical interface lanes which operate in 25G NRZ encoding mode resulting in 200G (8x25G) data rate. The 2x100GBASE-SR4 AOC assemblies are used to connect multiple 200G signals from the server side (NICs) to the data center aggregation switch.

 | 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. |
