Title:
O-BAND TUNABLE OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2022/142068
Kind Code:
A1
Abstract:
The present application discloses an O-band tunable optical module. The O-band tunable optical module comprises: a microprocessor circuit, a select switch and a transmitter optical subassembly (TOSA). The TOSA comprises a plurality of laser devices, and different laser devices respectively cover different wavelength ranges, the microprocessor circuit comprises a select signal port and a current signal port, and the select switch comprises a common port, a control port and a plurality of output ports. The select signal port is connected to the control port, the current signal port is connected to the common port, and the output ports are respectively connected to the corresponding laser devices. The microprocessor circuit is configured to control the common port of the select switch to be selectively connected to a corresponding output port, so as to connect the current signal port to a corresponding laser device; and the microprocessor circuit is configured to input a current signal to the corresponding laser device by means of the current signal port, so as to turn on the corresponding laser device.
