Brief Introduction
The Vchung QSFP-DD 400G Digital Coherent Optical (DCO) 0dBm Open ZR+ transceiver is a 400 Gbit/s multirate pluggable module for 100/200/300/400GBASE Ethernet optical data communication. The transceiver operates with dual polarization quadrature amplitude modulation (DP-16QAM) and oFEC to achieve up to 120 km reach without the requirement of EDFA (Erbium-Doped Fiber Amplifier ) or DCM (Dispersion Compensation Module).
The module is fully compliant with QSFP-DD related MSA standards and CMIS. Digital Diagnostic functions are available through an I2C interface.

 | 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. |
