800G OSFP SR8 Optical Transceiver Module is a very important network communication component that can transmit data from one network node to another. Here is the detailed knowledge about this optical transceiver module, including its introduction, technical principles, features, application scenarios and advantages.
800G OSFP SR8 Optical Transceiver Module Introduction
The 800G OSFP SR8 optical transceiver module is a hot-swappable fiber optic transceiver module designed for data center 800G SR8 Ethernet links. This module adopts the latest 100G PAM4 and VCSEL technology, which can realize 800G data interconnection within 100m. The availability of this module allows data centers to achieve more efficient and reliable data transmission when performing high-speed data transmission.
Technology Principle
100G PAM4 Technology
100G PAM4 technology is a modulation technology that transmits data in the form of pulses. Compared with traditional binary signals, PAM4 signals have a higher bandwidth utilization, so higher data transmission rates can be achieved. In the 800G OSFP SR8 optical transceiver module, PAM4 technology is used to realize 800G high-speed data transmission.
VCSEL Technology
VCSEL, or vertical cavity surface emitting laser, is a laser fabricated on a semiconductor chip with the emission direction perpendicular to the surface of the semiconductor chip.VCSEL has the advantages of low power consumption, low cost, and high reliability, so it is widely used in the communication field. In the 800G OSFP SR8 optical transceiver module, VCSEL is used as a transmitting light source to transmit data to the destination via optical fiber.
Characteristics
High Reliability
The 800G OSFP SR8 optical transceiver module has high reliability and can work stably for a long time in a high-density environment.
Hot-swappable
The module adopts a hot-swappable design, which is convenient for users to replace and maintain without interrupting the network connection.
Low Energy Consumption
Due to the use of highly efficient VCSEL technology, the module has low energy consumption, which helps data centers achieve energy saving and emission reduction.
High-speed data transmission
The module can realize 800G high-speed data interconnection within 100m, which improves the data transmission efficiency of the data center.
Application Scenarios
Data Center
Data center is the main application scenario of 800G OSFP SR8 optical transceiver module. The module can realize fast data transmission between servers and switches within the data center.
Communication Network
In communication networks, the module can be used as a fiber optic transmission channel to achieve high-speed data transmission between different nodes.
AI Supercomputing
AI is based on parallel computing, and the core processor is mainly GPU, but in addition to GPU performance, the communication factor can be a shortcoming that restricts supercomputing, and as long as there is a network blockage in one of the links, data delay will occur. Therefore, the AI server for the underlying data transmission rate and latency requirements are very demanding, requiring high speed optical modules to match, so the AI server has a great demand for 800G optical modules.
Summary
The 800G OSFP SR8 optical transceiver module is a high-speed, reliable, energy-efficient pluggable optical transceiver module suitable for data centers, communication networks, AI supercomputing and other scenarios. Its appearance makes data centers more efficient and reliable in high-speed data transmission, while reducing energy consumption, bringing important contributions to the development of modern communication technology.
