NO.59 Which of the following is the multiplexing method of SDH?

NO.60 The OTN signal has a fixed pad period, the same frame period as the SDH signal.

NO.61 STM-64 has an () AU pointer.

NO.62 When the J1 byte does not match, an alarm () is reported and the service may be interrupted.

NO.63 Which of the following statements about the clock source are incorrect?

NO.64 The1310nm and 1550nm transmission windows are low loss windows. In DWDM systems, only the 1560m transfer window is used. Which of the following is the main cause?

NO.65 For (on-premises) HA solutions where active and standby servers are deployed in the same location, which of the following platforms can be deployed? (Multiple choice).

NO.66 The index is used to folio and delineate the starting position of VC-n in the corresponding AU or TU frame so that the receiving end can correctly remove the corresponding VC from the STM-N The VC and C packages are then separated into separate low-rate signals, such as PDH That is; Low-rate branch signals can be discarded directly from the STM-N signal

NO.71 In the SDH optical synchronous transmission system, which of the following bytes is used to transmit the quality and weight and usage information of the clock source?

NO.72 The receiver performs a BIP-8 check on unscrambled STM-16 frames. If the BIP8 check result XOR*∶, the value of the B1 byte contained in the next STM16 ring is 10001100, which indicates STM-16 There is a () bit error block in the axis.

NO.73 Which of the following are device-level protection schemes for SDH products? (Multiple choice).

NO.74 Which factors determine the optical signal-to-noise ratio (OSNR) of the receiving end to a certain extent After the signal transmission in the WOM system is transmitted over a certain distance, the “oSNR” of the receiving end of the optical signal-to-noise ratio is reduced to a certain extent.
