Brief Introduction
The Vchung 800GBASE-2LR4+ QSFP-DD transceiver supports link lengths of up to 10 km over single-mode fiber (SMF) via dual LC connectors. It complies with IEEE 802.3ck, QSFP-DD MSA, and CMIS Rev 5.0 standards. The transceiver features built-in digital diagnostics monitoring (DDM) for real-time access to operating parameters. It is ideal for 800G Ethernet, Breakout 2x 400G LR4, and data center applications.

 | 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. |
