1.400g qsfp-dd coherent pluggable module

    The flexibility of pluggable interfaces has always been the main factor for the success of Ethernet optical transmission,and coherent optical modules have played an important role in modern long-distance optical fiber communication links.They usually focus on the highest performance and use customized optical devices and ASICs on large fixed modules.The 400g ER1 qsfp-dd coherent pluggable optical module provides client multiplexing and Interoperability Based on OIF and openzr+protocols.The transmission distance can reach 40km on the non amplified link and will be used for access,parks and 5g networks.

2.50g SFP 56 FR/LR series optical module

   When applied to 5g forward transmission,dual carrier is an important product direction in improving the overall network capacity.At the same time,dual carrier technology also highly conforms to the domestic development plan and meets the needs of operators for network construction.The forward transmission under dual carrier aggregation is mainly 2x25g.However,with the coordinated progress of technology and industry chain,the demand for single channel 50g optical modules is about to mature,and 50g SFP 56 FR/LR series optical modules for wireless network applications are launched.The 50g SFP 56 FR and 50g SFP 56 LR optical modules meet the IEEE 802.3cd standard.They are both packaged in SFP 56 and support users to flexibly select 2x25g NRZ and 1x50g pam4 electrical signal modulation.The optical signal is modulated by 50g pam4,which is applicable to industrial grade temperature(-40°C to+85°C)and supports transmission distances of 2 km and 10 km respectively.

3.12g SDI optical module

   With the increasing demands on video picture quality and transmission distance for live broadcast of remote teaching,telemedicine and sports events,the 12g SDI optical module can just meet the needs of high-definition video transmission.12g SDI is a scheme applied to 4K ultra clear video optical transmission.The difference from ordinary optical modules lies in the encoding mode of video data stream and telecommunication data.In addition,a"sick code test"of video standard needs to be achieved to complete the transmission and transmission of data signals,so as to ensure the clarity and stability of video.The main principle is that the 12g SDI can integrate four 3g-sdi signal lines into one to realize 4K audio and video transmission.
