The OTUk frame rate can be concluded based on OTU1, OTU2, and OTU3 frame rates. Which of the following is the correct formula for calculating the OTUk frame rate?
The formula to calculate the OTUk frame rate is: OTUk frame rate = 255 / (239 - k) × STM-N frame rate. Here, "k" represents the OTUk version index, and STM-N is the synchronous transport module rate. This formula derives from the OTN standard, adjusting the frame rate according to the version and allows synchronization with underlying SDH/SONET rates. HCIP-Transmission materials provide this formula for engineers to correctly understand and calculate transmission rates for different OTN layers.
