Brief Introduction
The Vchung 800G QSFP-DD DAC is a high-speed, cost-effective alternative to fiber optics in 800G Ethernet applications. It contains 16 high-speed copper pairs, each operating at data rates of up to 100Gb/s. This cable is compliant with IEEE 802.3ck Ethernet standard and QSFP-DD MSA Compliant (Multi-Source Agreement).
With these features, they provide power-efficient connectivity for short-distance interconnects and enable higher port bandwidth, density and configurability in the data centers.

 | 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. |
