    摘要： An optical network transmitter comprises a fractional-bit module, an optical modulator coupled to the fractional-bit delay module and a band-limiting optical filter coupled to the optical modulator. A transmission system comprises a source configured to generate two complementary binary data streams, a fractional-bit delay module in communication with the source and configured to delay one of the complementary binary data streams, a modulation module in communication with the source and the fractional-bit delay module and configured to convert the undelayed complementary binary data streams and the delayed complementary binary data streams into a fractional-bit delayed optical duobinary signal, and a band-limiting node in communication with the modulation module and configured to filter and transmit the optical duobinary signal.

    摘要： This application provides an optical power commissioning method, a commissioning system, a control device, and a commissioning station. The commissioning system includes a control device and one or more commissioning stations. The method includes: The control device first identifies one or more to-be-commissioned services on which optical power commissioning needs to be performed; the control device sends, based on the to-be-commissioned service, commissioning information to the one or more commissioning stations on which the to-be-commissioned service passes through, where the commissioning information is used by the one or more commissioning stations to perform parallel optical power commissioning; and the one or more commissioning stations perform optical power commissioning based on the commissioning information. According to this application, a plurality of services and a plurality of commissioning stations can be commissioned concurrently. This improves commissioning efficiency, and is further applicable to more commissioning scenarios.
