Brief Introduction
The Vchung VC-QSFPDD-800G-SR8 is an 8-Channel, Pluggable, Fiber-Optic QSFP-DD for 800Gbps SR8 Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 106.25Gbps per lane up to 50m using OM3 fiber and 100m using OM4 fiber. The optical interface uses MPO receptacles. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 76 contact edge type connector.

 | 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. |
