The optical module is used to convert the 100G electrical signal in each QSFP28 port into a 100G incoherent optical signal and output it to the device.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] refer to Figure 1-5A communication service conversion device based on a 400G optical module includes a coherent optical conversion module, a main control module and an optical module. The coherent optical conversion module is used to receive a 400G optical signal and convert the 400G optical signal into four 100G electrical signals. The main control module is used to receive four 100G electrical signals and distribute the four 100G electrical signals to four QSFP28 ports. The optical module is used to convert the 100G electrical signal in each QSFP28 port into a 100G incoherent optical signal and output it to the device.

[0020] In this embodiment, by setting a coherent optical conversion module, a main control module and an optical module, the coherent optical conversion module converts the 400G optical signal into four 100G electrical signals, the main control module distributes the four 100G electrical signals to four QSFP28 ports, and the optical module converts the 100G electrical signal in each QSFP28 port into a 100G incoherent optical signal, which can stably transmit the signal to the corresponding device, thereby effectively solving the defect of the prior art that the signal is prone to instability and affects the conversion efficiency of communication services.

[0021] Preferably, the coherent optical conversion module includes a QSFP28-DD chip and its peripheral circuits.

[0022] Preferably, the main control module includes a gearbox chip and its peripheral circuits.

[0023] Preferably, the optical module includes a QSFP28 chip and its peripheral circuits.

[0024] Specifically, the 400G-QDD coherent optical module converts the 400G optical signal into four 100G electrical signals. Each 100G electrical signal has two signal lines. The 100G electrical signal of the traditional 100G_Q28 module has four signal lines, so it needs to be converted through the gearbox chip. The four 100G electrical signals are connected to the gearbox chip. The gearbox chip can multiplex the four 100G electrical signals into 100G electrical signals with four signal lines compatible with Q28 according to actual needs, and distribute them to four QSFP28 ports. The QSFP28 port converts the 100G electrical signal into a 100G incoherent optical signal through the QSFP28 chip and outputs it to the device.

[0026] Preferably, the monitoring module includes an MCU chip and its peripheral circuits.

[0027] In this embodiment, by setting up a monitoring module, the monitoring module can read and access relevant data of the coherent optical conversion module, the main control module and the optical module. By reading these data through the network management, the performance of the business communication can be monitored in real time, and corrections can be made in time, thereby further ensuring that the signal can be stably transmitted to the corresponding device.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
