Brief Introduction
The Vchung 200G QSFP28-DD Copper Twinax Cable is a portfolio of passive Direct Attach Copper (DAC) cables as high-speed, cost-effective alternatives to fiber optics in 200G Ethernet applications. The 200G QSFP-DD DAC cable contains 16 high-speed copper pairs, each operating at data rates of up to 25Gb/s. Each QSFP-DD port comprises an EEPROM providing product information, which can be read by the host system.

 | 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. |
