H31-311_V2.5 Exam Dumps - Huawei Transmission Questions and Answers

Which of the following bytes in the regenerator part overhead are associated with R-OOF and R-LOF? (Multiple Choices)

RSOH, MSOH, HPOH and LPOH implement the monitoring function in descending order of the monitoring fan country.

The refractive index n1 of the fiber core must be the Q of the cladding refractive Mo n2, which is a necessary condition for transmitting the optical signal in the optical fiber.

For alignment; Indicates the starting position of VC-n in the corresponding AU or TU frame. • This way: The receiver can correctly remove the corresponding VC from STM-N, and then The VC and C packages are separated into separate low-rate signals, such as PDH, which means that the low-rate path signal can be dropped directly from the STM-N signal.

The working mode of the port determines the flow control mode of the port.

When the operating mode is 100Mbit/s full duplex, one of the following flow control modes can be used

Which of the following ITLI-T recommendations define the OTN frame structure?

Both PDH and SDH have globally harmonized standards.

The segment overhead of STM-4 is () bytes/frame.

According to the formula "OTUk rate = 255/(239 - k) x STM-N frame rate", the OTU3 signal rate is 255/236 x STM-N frame rate.

Which of the following types of optical fibers has the zero-dispersion feature at 1310 nm?
