The 400G optical module PCB is a high-frequency, high-speed printed circuit board specifically engineered for next-generation optical transceivers operating at 400Gbps data rates. Manufactured using advanced low-loss materials such as RO5880 high-frequency microwave laminate, MEGTRON 6, or hybrid stacks combining IT968TC and S1000-2M, this 10-layer board delivers exceptional signal integrity with minimized insertion loss and stable dielectric properties at high frequencies. Featuring HDI technology with laser-drilled microvias (0.10mm), fine line/space geometries down to 0.075mm/0.075mm, and tight impedance control (100±7%Ω, 50±10%), the 400G optical module PCB supports PAM4 modulation schemes up to 50Gbps per lane. With partial hard gold plating up to 50μ″ for enhanced wear resistance on contact fingers and ENIG or immersion silver surface finishes, this board is the ideal substrate for QSFP-DD, OSFP, and CFP8 form factor optical transceivers deployed in hyperscale data centers, AI clusters, and 5G communication infrastructure.
