Supplier of POET in China
The closest supplier of POET in China is Sanan Optoelectronics. In 2021, the two parties jointly established Xiamen SPX to bond San'an's InP chip to the optical intermediate layer and then sell it to domestic optical module suppliers. In 2023, SPX announced the receipt of purchase orders. Our team has ordered additional precision chip bonders, testers and additional equipment, which will expand production capacity. SPX uses semiconductor bonding machine. In 2024, POET acquired the equity of San'an, saying that the acquisition would enable POET to control SPX and expand its wafer-level assembly business outside China. At the same time, POET negotiated with several manufacturers in Malaysia and finally signed a contract with NationGates. In 2025, San'an Optoelectronics said that Quanzhou Guangtong has launched 70/100mWHPDFB products with silicon light technology. 100GDML products are under development. Quanzhou Guangtong's withdrawal from the SPX joint venture system is based on the consideration of geopolitical factors. At present, Quanzhou Guangtong's laser light sources and detector products have been matured, and the business cooperation with POET is still being carried out normally.
