800G Multimode Optical Transceiver-Your Choice for High-Speed Interconnection in AI & Data Centers

As the AI era advances, the demand for computing power has sharply increased. Data centers also have growing needs for bandwidth, capacity, and lower latency, driving the development of faster network speed, and prompting a surge in demand for 800G high-speed optical transceivers.


There are over 1.3 billion fixed broadband users worldwide, with over 50% of users already using FTTH. PON is an important system for providing high-speed internet, and its technology greatly reduces the cost of network construction and maintenance compared to traditional networks, with its usage continuing to rise. At this year’s FTTH exhibition, ATOP also showcased PON series products, including GPON OLT, XGS PON OLT, XG COMBO PON OLT, XGS COMBO PON OLT, GPON ONU, and XGS PON ONU etc. As an important component of broadband access network architecture, they play a crucial role in providing users with high-speed data and video services, providing on-demand network construction advantages based on specific network requirements, helping customers reduce network construction and maintenance costs, and building green networks that are energy-efficient and reduce emissions. The following diagram can give you a quick understanding of the application of ATOPu2019s PON modules in broadband access network architecture.

ATOP 800G OSFP/QSFP-DD SR8, complies with the IEEE 802.3ck-defined 800GAUI-8 standard. It adopts OSFP/QSFP-DD packaging and is specifically designed for use on multimode optical fibers for 800 Gigabit Ethernet links. The product features 8 independent electrical signal input/output channels, each operating at a speed of 106.25 Gbps, with a maximum supported transmission distance of 100 meters. It is applicable to AI, data centers and 800G Ethernet, with typical application power consumption as low as 13W. The DSP adopts 7nm process with mature chip flow and reliable performance.
