Major global manufacturers of 800G Optical Module PCB include Unimicron Technology, Shengyi Electronics, Shennan Circuits, Shenzhen Kinwong Electronic, Shenzhen Zecheng Electronics, Huizhou CEE Technology Inc., Victory Giant Technology (HuiZhou), Shenzhen Fastprint Circuit. An 800G optical module PCB carries high-speed electrical lanes between the module connector, DSP or retimer, drivers, TIAs and optical engine. In an OSFP implementation, 800G is commonly supported by eight high-speed electrical lanes. The board must preserve insertion loss, return loss, crosstalk. According to our (Global Info Research) latest study, the global 800G Optical Module PCB market size was valued at US$ 1185 million in 2024 and is forecast to a readjusted size of USD 1958 million by 2031 with a CAGR of 7. Unlike traditional binary (2-level) modulation, PAM4 uses four levels of signal amplitude to represent two bits of data per symbol. This guide explains the key PCB technologies, materials, manufacturing processes, and cost considerations for 400G and 800G optical modules in 2026. What Are 400G and 800G Optical Modules? 2.
