Abstract: With the surge in internet traffic driving the upgrade of optical fiber communication infrastructure, high-speed optical communication devices are ushering in a new wave of rapid growth. As the largest single market and industrial chain for optical communication globally, China not only boasts strong capabilities in optical device modules but also sees the rapid rise of optical communication chips, especially the domestic high-end 25G chips, which have garnered significant demand in the market. In response to the explosive market demand, Zhejiang Guangte Technology Co., Ltd., a Chinese developer and manufacturer of photonic integrated chips, officially announced that its 25G PIN and 4x25G PIN Array have been recognized by customers, achieving small-batch shipments and possessing the capability for mass supply. Dr. Ye (founder of Zhejiang Guangte) told Xunshi that after years of research and development accumulation, Zhejiang Guangte is ready to supply domestic high-end optical chips to the market at the node of exploding demand for high-speed optical devices, in conjunction with the deployment of 5G commercial systems and the construction of data centers.

ICCSZ News: With the surge in internet traffic driving the upgrade of optical fiber communication infrastructure, high-speed optical communication devices are experiencing a new wave of rapid growth. As the largest single market and industrial chain for optical communication globally, China not only boasts strong capabilities in optical device modules but also sees the rapid rise of optical communication chips, especially with domestic high-end 25G chips enjoying significant demand in the market.

In response to the explosive market demand, Zhejiang Guangte Technology Co., Ltd., a developer and manufacturer of photonic integrated chips in China, officially announced that its 25G PIN and 4x25G PIN Array have been recognized by customers, achieved small-scale shipments, and possess the capability for large-scale supply. Dr. Ye (founder of Zhejiang Guangte) told Xunshi that after years of research and development accumulation, Zhejiang Guangte is ready to supply domestic high-end optical chips to the market at the node of explosive demand for high-speed optical devices, in conjunction with the deployment of 5G commercial systems and the construction of data centers.

According to Xunshi, the DC internal connection between 5G fronthaul and data center servers-TOR switches will require tens of millions of 25G high-speed optical modules. Zhejiang Guangte's 25G PIN PD directly meets the requirements of 25G high-speed optical modules, enabling high-speed transmission at the network front end.

Meanwhile, in the fields of backhaul and data center interconnection in 5G, there is a demand for high-end 100G/200G/400G optical modules, which will adopt a four-channel chip integration array approach, with a single-channel 25Gbps rate as the foundation. Guangte Technology's 25G PIN and 4X25G PIN have the advantages of high responsivity, low capacitance, and low dark current, making this series of products extremely suitable for high-bandwidth, high-sensitivity optical receiving devices.

Currently, 25G chips will be heavily utilized in data center 100G/200G/400G optical modules, 5G fronthaul 25G, and mid-to-backhaul 100G/200G/400G optical modules. The access network is also accelerating the upgrade to 10G PON. The rise of the high-end optical module market will drive sustained demand for 10G/25G chips. This time, Zhejiang Guangte's 25G PIN and 4X25G PIN Array are ready for mass production, meeting the growing demand in the high-end market head-on and entering a larger growth cycle.
