brand design
Optical Transceiver is a key device to realize the conversion of signal and optical signal. It is widely used in high-speed transmission scenarios such as data centers, 5G networks, and AI training clusters. Its main functions include:


1. Ultra-high speed transmission

The high-speed Optical Transceiver represented by 400G and 800G achieves data transmission capabilities of hundreds of Gbps per second, and bandwidth-intensive requirements such as AI large-scale model training, high-definition video streaming, and multi-node server interconnection.
 

2. Low power design

The advanced photoelectric conversion process consumes a large amount of power, which not only improves the energy efficiency ratio (PUE) of the data center, but also responds to the global trend of "green computing power" and saves operation and maintenance costs for enterprises.
 

3. High integration and miniaturization

The module integration is improved, the size is smaller, and the port density is higher. It is especially suitable for high-density deployment scenarios, such as ultra-large-scale GPU clusters and edge computing nodes.
 

4. High compatibility and reliability

It is seamlessly compatible with mainstream switches and network cards, adapts to the industrial temperature range of-40 °C to 85 °C, and ensures stable operation in complex environments.

Typical Application Scenarios of Optical Transceiver
1. AI Intelligent Computing Center
AI training models such as DeepSeek, GPT, etc. need to process EB-level data. 800GOptical Transceiver plays a key role in the Top of Rack (TOR) to Spine interconnection, ensuring low-latency, high-bandwidth data synchronization between GPU nodes. Allrunopti is actively developing the next-generation 1.6 TOptical Transceiver to lay out ahead of the future AI computing power layout.

2. Hyperscale data centers
High-density deployments centered on the Leaf-Spine architecture require Optical Transceiver to support short (< 500m) and long (> 10km) transmissions. Allrunopti has launched a variety of modules based on QSFP-DD and OSFP packages, taking into account various scenarios and transmission stability.

3. 5G-A and edge computing
5G-A/6G networks require millisecond-level delay guarantee, and edge data centers require miniaturization and wide temperature adaptation. Allrunopti offers a variety of 400GZR + and 800GDR8 Optical Transceivers to help operators build high network infrastructure.

4. Highly reliable application of finance and scientific research
Scenarios such as securities and supercomputing centers have extremely high requirements for delay and reliability. Allrunopti products have passed industry standard tests and can be widely used in key areas such as quantum computing and financial transactions.

With its strong R&D and system integration capabilities, Allrunopti has deeply deployed in the field of high-speed optical communications. The company anchors the core track of 400G/800G Optical Transceiver and optical switches, focusing on key markets such as AI computing power centers, edge nodes, and digital transformation with government and enterprises, aiming to build a high-quality provider of intelligent optical network solutions that is leading in China and in line with international standards.

 
Optical Transceiver

At present, Allrunopti has joined hands with partners to invest in the research and development of 1.6 T Optical Transceiver, seize the core channel of the next-generation intelligent computing center, and plan future key directions: large-scale application of silicon photonics and CPO: module power consumption, improving transmission density; Research and development of intelligent operation and maintenance system: realize the automatic scheduling and monitoring of the whole process of the intelligent computing center; Distributed computing power network construction: Provide flexible and highly reliable optical communication support for diverse scenarios.

According to Cignal AI data, the global high-speed Optical Transceiver market will exceed US $9 billion in 2024, and will expand in 2025. China's "East Counting and West Counting" project and the "Green Data Center" policy have been implemented, opening up a 100 billion-level market for local optical communication companies. Allrunopti, as the innovative force of the new generation of Optical Transceiver and switching equipment, is becoming an important force behind China's computing power network. On the journey towards the 1.6 T, 3.2 T and even 6.4 T ultra-high-speed era, Allrunopti is willing to work with industry partners to build a reliable and intelligent digital future.
