Zusammenfassung:An optical module and an optical line terminal device are disclosed. According to an example, the optical line terminal device comprises a system board and an optical module. The system board comprises an optical module control circuit comprising a main control chip and a drive circuit. The optical module comprises a circuit board provided with an electrical interface, an optical assembly and a memory unit, The memory unit is configured to store an operation parameter of the optical assembly. The electrical interface has a first pin to be connected with a drive end of the optical assembly and a second pin to be connected with a data transmission pin of the memory unit. In this way, main control chip is allowed to read the operation parameter of the optical assembly through the first pin and configure the drive circuit accordingly, while the drive circuit is allowed to drive the optical assembly through the second pin.
