질문 21
The frame structure of ODU4 is four times that of ODU1

질문 22
The optical amplifier unit compensates for line losses and extends the transmission distance. Connecting multiple optical amplifier units in cascaded mode allows for extended transmission distances without following the system.

질문 23
EPL services use bandwidth exclusively on the line, which is very safe. Dedicated line applications for VIP customers

질문 24
Only one TCM can be used at one site

질문 25
In WDM systems, it is ideal to use a dielectric thin film filter (TFF) when using less than () wavelengths.

질문 26
Single-fiber bidirectional WDM systems use only one optical fiber to transmit optical signals in both directions at the same time. Light signals in both directions should be arranged at different wavelengths.

질문 27
Which of the following statements about ODUk_PM_BDI is correct?

질문 28
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.

질문 29
Compared with dense wavelength division multiplexing (DWDM) systems, crude glass division multiplexing (CWDM) systems provide a certain amount of glass length and transmission distance within (kmkm), which greatly reduces system cost and has strong flexibility

질문 30
When the U2000 is synchronized, the same network metadata as the U2000 is not uploaded to the U2000, and the data that exists on the U200 but does not exist on the network element is deleted.

질문 31
The number of ODU2e signals multiplexed into the ODU3 signal is the same as the number of ODU2 signals multiplexed into the ODU3 signal

질문 32
Which of the following is the electrical layer cost of OTN? (Multiple choice).

질문 33
The dual fiber ring topology consisting of three network elements is arranged in counterclockwise order as the service between A, B and C A and C occupies the first VC-48 on the short path VC-12 time slots, B and C of the same service also occupy the 48th of the first VC-4 on the short path VC-12 time slots

질문 34
When the working PQ1 board is oversized, the device will perform and the TFS protection will be reversed. Which of the following statements about the switching process are correct? (Multiple choice).

질문 35
Which of the following statements about overhead bytes is incorrect?

질문 36
Which of the following is photolayer tracking? (Multiple Choices)

질문 37
Which of the following bridges are used to forward data based on the MAC address and VLAN ID carried in the data?

질문 38
OChr means the use of electrical monitoring technology.

질문 39
Which of the following is the steps to multiplex a low-speed service into a high-speed SDH service? (Multiple choice).

질문 40
In the Windows operating system, the log files of the U2000 program are stored in the () directory of the U2000 installation disk.

질문 41
When the bridge uses ivl learning mode, an entry in the MAC address table is created based on the source MAC address and source port of the teach frame. This entry applies to all VLANs

질문 42
Which of the following ITLI-T recommendations define the OTN frame structure?

질문 43
Some SNCP protection inversion conditions are default, such as AU-AIS and TU-AIS. Other conditions are optional, such as HP-TIM and HP-SLM. Optional conditions can be flexibly set according to the level of the costume.

질문 44
output networks require higher costs than belt networks, but provide a more reliable management channel.

질문 45
Linear MSP (LMSP) has two modes: 1+1 and 1:1. Additional services can only be configured for the protection channel in 1:1 mode of the LMSP.
