Shijia Photons’DR4/DR8 optical fiber MPO components for 800G application use a FA front-end mounted magnetic isolator at the TX end, with a FA and 42 ° polished fan in and fan out waveguide coupling at the RX end to achieve MFD conversion, which can better match the coupling requirements of the 800G optical module optical engine. DR4/DR8 fiber optic MPO assemblies products have good optical performance and excellent long-term reliability, and are widely used in the production of 400G/800G optical modules. The products can also provide solutions for high-speed optical interconnection technology of CPO.
