The 800G QSFP-DD transceiver is crucial for innovation and advancements in the data transmission industry, driving excitement and anticipation for its development trends.
800G QSFP-DD Wiki
The 800G optical transceiver is a high-speed optoelectronic conversion device used for achieving 800Gbps data transmission. It adopts small form-factor packaging types, such as QSFP-DD or OSFP, to transmit data signals through optical fibers. Common models of these optical modules include 2FR4, DR8, XDR8, 2LR4, and PLR8, which are suitable for application environments like high-performance computing, cloud computing, and data centers.
800G Transceiver Features
High-Speed Transmission
The QSFP-DD 800G transceiver utilizes coherent optical communication technology and DSP chips to achieve high-speed transmission. Coherent optical communication technology plays a vital role in encoding and decoding digital data into optical signals, allowing for the transmission of large amounts of data by adjusting the phase and amplitude of the light signal. The DSP chip is responsible for signal conditioning and encoding/decoding, optimizing the transmission quality. By combining advanced modulation formats, the 800G optical module achieves higher data rates to meet the demands of high bandwidth.
High-Order Modulation and Cellular Technology
The 800G QSFP-DD optical module supports a 16QAM modulation scheme with a modulation rate of 120GBaud, making it suitable for scenarios that require high-speed and high-capacity data transmission. And it uses multiple channels to transmit data in the 800G optical transmission system. Each channel can independently transmit data, thereby increasing the overall system capacity and throughput.
Multi-Channel Design
The 800G transceiver adopts an 8-channel design, with each channel having a transmission rate of 100Gbps or 200Gbps. The multi-channel design increases the transmission bandwidth and provides higher data throughput.
Dual-Density Design
The 800G optical transceiver supports a dual-density design, where one module can provide two different connection options. For example, by changing the internal arrangement of the module, it can achieve two 100Gbps channels or two 200Gbps channels.
