Optical module and 5G communication network with 1588 time synchronization

The utility model relates to an optical module and a 5G communication network with 1588 time synchronization. The optical module comprises a receiver unit and an optical module unit. The receiver unit is provided with a signal input interface which is used for connecting an antenna; the receiver unit is connected with the optical module unit, and the receiver unit is used for recovering the time of a source satellite by using a satellite signal, generating a 1PPS pulse signal when the recovered time is a whole second, and sending the 1PPS pulse signal to the optical module unit; the receiver unit is connected with the optical module unit through the protocol conversion module, and the protocol conversion module is used for converting the current time second value of the receiver unit into a TOD protocol format signal and transmitting the TOD protocol format signal to the optical module unit when the recovery time of the receiver unit is a whole second; the signal output interface of the optical module unit is
