AI Technical Summary
⚠Technical Problem
In passive optical networks, how can lossless adjustment be achieved when the bandwidth of service data decreases to ensure the reliability of service data transmission?
⚗Method used
By reducing the bit rate of the data frame and decreasing the length of the transmission frame, the data frame is mapped onto the transmission frame with a reduced length, thus achieving lossless bandwidth reduction.
🎯Benefits of technology
This ensures the reliability and stability of business data transmission even when business data bandwidth is reduced.

Abstract
The present application provides a method for bandwidth reduction, and a device. The method comprises: after the bit rate of a data frame is reduced from a first bit rate to a second bit rate, reducing the length of a first transmission frame; and mapping the data frame at the second bit rate to the first transmission frame after the length reduction. When the bandwidth of service data needs to be reduced, the bit rate of a data frame is first reduced, then the length of a transmission frame is reduced, and the data frame after the bit rate reduction is mapped to the transmission frame after the length reduction, thereby ensuring the reliability of service data transmission.
