Dear Friendwith the increasing requirements for bandwidth, port density and system energy consumption, 400G transceivers become more and more popular, But the regular QSFP-DD 400G can only reach 500M~ 40KM.If any longer distance, the cost will be very high. here we would like to recommend this 400G QSFP-DD ZR and ZR+ which can solve the 400G long distance transmission:400G Open ZR+ QSFP-DD DCO modules based on DP-16QAM supporting extended C-band, polarization diversity coherent detection and advanced electronic link equalization. Chromatic dispersion compensation can be applied to the receive side of the demodulator. This module is managed utilizing the Two Wire Interface that is specified in the Common Management Interface Specification (CMIS)If you are interested in this module, please feel free to contact us.Best Regards Sales ManagerShenzhen Sky Optics Technology Co., LTD
