NO.29 Which of the following statements about basic LCAS functionality are correct? (Multiple choice).

NO.30 The difference between dispersion compensation fibers and ordinary optical fibers is that the dispersion compensation fibers have a negative dispersion coefficient at ().

NO.31 What are the basic features of the U2000? Multiple Choices

NO.32 When using a script to back up U2000 data, the backup speed is fast because the backup file is small.

NO.33 When configuring LMSP, there are two switching modes: single-ended switching and double-ended switching. Single-ended switching does not require the protection protocol to be enabled.

NO.34 output networks require higher costs than belt networks, but provide a more reliable management channel.

NO.35 Which of the following bytes can be used for ordenwire calls between two REG devices?

NO.36 Which of the following is the meaning of “L” in the optical module parameter “L-64.2”

NO.37 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.

NO.38 Which overhead below 112 is not ODUk overhead?

NO.39 In the OSN550, the CXL slot contains a function board that integrates a system control and communication (SCC) unit, a cross-connecting unit, and a clock unit Depending on the functionality and access features provided by the OSN550, there are several types of dashboards

NO.40 Which of the following alarm/event storage modes does U2000 support? (Multiple choice).

NO.41 After configuring PDH on a per-net element basis, the full trace cannot be searched. Which of the following is a possible cause? (Multiple choice)

NO.42 In the frame structure of the SDH signal, there are large overhead bytes for operation, management, and maintenance (OAM). Overhead bytes account for all bits () of the entire frame and greatly enhance the monitoring capabilities of the network.

NO.43 For osn3500, which of the following boards provides centralized backup capability for the +3.3V power supply of each board in the sub-shelf?

NO.44 Automatic Laser Shutdown (ALS): When no optical signal is received, the ALS function automatically turns off the corresponding optical module. This feature protects field maintenance personnel.

NO.45 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.46 Which of the following clock operating modes supports the ITU-T G.781 standard? (Multiple choice).

NO.47 When the sender detects that the b6-b8 of the K2 byte is 110, it means that the sender has reported an alarm ().
