NO.14 Which of the following descriptions of the OTUk frame format is wrong?

NO.15 Which of the following different types of ESC are divided according to the principles of implementation?
(Multiple choice)

NO.16 Fiber amplifiers can be divided into rare earth ion doped fiber amplifiers (Rare Earth Ion Doped Fiber Amplifier) and nonlinear fiber amplifiers. The working principle of rare earth ion doped fiber amplifiers is stimulated radiation; while nonlinear fiber amplifiers use the nonlinear effect of optical fibers to amplify optical signals.

NO.17 Subnet division can reduce network traffic, improve network performance and simplify management.

NO.18 QinQ technology can be used when multiple users need to share the same VCTRUNK and use the same VLAN ID.

NO.19 K1 and K2 bytes can send APS switching signaling or indicate that the multiplexed segment signal is invalid.

NO.20 Which of the following is photolayer tracking? (Multiple Choices)

NO.21 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.22 A subnet can contain other subnets.

NO.23 What is the structure of STM-16?

NO.24 The SDH network does not change the structure and rate of the client-side signal.

NO.25 In the integrated DWDM system, the transmitting light source must strictly comply with the G.693 optical port specifications.

NO.26 Automatic Laser Shutdown (ALS): When no optical signal is received, the ALS function automatically shuts down the corresponding optical module. This function protects on-site maintenance personnel.

NO.27 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.28 Which of the following are the main advantages of SDH? (Multiple choice)

NO.29 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.30 In WDM network design, as long as enough EDFAs are cascaded to compensate for the optical power loss during transmission, the system can transmit over a long distance without limitation.

NO.31 Arrayed Guided Grating (AWG) multiplexer/demultiplexer has the following advantages: short wavelength spacing, large channels and flat passband. It is suitable for ultra-high-speed, large-capacity DWDM systems.

NO.32 The flexible pipe provided by MS-OTN equipment means that the service can be carried through ODUk or PW.

NO.33 TU-AIS is often encountered during network maintenance. Which of the following alerts can trigger a TU-AIS alert? (Multiple choice).

NO.34 The segment overhead of STM-4 is 9+9+4 lines/frame.

NO.35 FAS is the frame alignment overhead, with a length of 6 bytes, located in the 1st row and the 1st to 6th columns. The 1st to 3rd bytes are 3 OA1 bytes, each OA1 is always “1111 0110”, which is F6 in hexadecimal. The 4th to 6th bytes are 3 OA2 bytes, each OA2 is always “0010 1000”, which is 28 in hexadecimal.

NO.36 Configuring the EPLAN service as a ring is not recommended. If the EPLAN service is configured as a ring network, the STP protocol must be enabled on the network to prevent broadcast storms.
