Brief Introduction
The Vchung 200G QSFP-DD ER4 Optical Transceiver modules are designed for using in 200Gigabit Ethernet 40km links over SMF single-mode fiber. They are compliant withtheQSFP-DD MSA and with IEEE 802.3cn 200GBASE-ER4 specification. Digital diagnostics functionsareavailable via the I2C interface as specified by CMIS V4.0. These modules can convert 8channels of 25Gbps (NRZ) electrical input data to 4 channels of 50Gbps (PAM4) optical signal, andalsocan convert 4 channels of 50Gbps (PAM4) optical signal to 8 channels of 25Gbps(NRZ)electrical output data. And these modules incorporate Gigalight Technologies provencircuit andEML technology to provide reliable long life, high performance, and consistent service.

 | 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. |
