Brief Introduction
The Vchung QSFP56 200G transceiver module is designed for use in 200 Gigabit Ethernet links up to 100m over OM4 and 70m over OM3 multi-mode fiber. The module has 4 independent electrical input/output channels operating at 53.125Gbp/s per channel. This transceiver consists of a transmitter/receiver unit operating on 850nm wavelength. The transmitter path of the module incorporates a PAM4 re-timer ASIC integrated with a 4-channel modulators driver, 4 externally modulated lasers. On the receiver path, there are 4 photodiodes and one 4-channel linear TIA arrays, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 200GAUI-4 interface as defined by IEEE 802.3bs.

 | 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. |
