Brief Introduction

The Vchung QSFP-DD 800G transceiver module is designed for use in 800 Gigabit Ethernet links over 100m OM4 and 60m OM3 fiber. The module has 8 independent electrical input/output channels operating at 106.25Gbps per channel. This transceiver consists of two transmitter/receiver units, with each operating on 850nm wavelengths. The transmitter path of the module incorporates a PAM4 re-timer ASIC with two 4-channel modulator drivers and 8 modulated lasers. On the receiver path, it consists of 8 photodiodes and two 4-channel TIAs, along with the PAM4 re-timer. The electrical interface of the module is compliant with the 800GAUI-8 interface as defined by IEEE 802.3ck,and compliant with QSFP-DD MSA.

QSFP-DD-800G-SR8 800G SR8 QSFP-DD 850nm 100m OM4 MMF MPO-16 TransceiversOptical 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.
