Which of the following paths has nothing to do with business?
- A . OCh
- B . OSC
- C . Client
- D . ODUk
In a wavelength division system, after a certain distance of transmission, the optical signal-to-noise ratio of the receiving end signal will be reduced to a certain extent. The main reason is ？
- A . The fiber attenuation is too large
- B . Use of demultiplexer
- C . Use of EDFA
- D . No new optical fiber is used
When the value of S1 byte is 0x02, it means ？
- A . G812 transfer office clock signal
- B . G812 local data clock signal
- C . Synchronization quality is agnostic
- D . G811 clock signal
Which of the following descriptions about pointer adjustment is correct ？
- A . When the rate of VC4 (frame rate) is higher than that of AU-4 (frame rate), it will be adjusted
- B . If the station detects that there is a low-level channel with a TU pointer adjustment event, it means that the station has a pointer adjustment
- C . AU and TU pointer adjustments are adjusted in units of 1 byte
- D . When the receiving end receives NDF inversion for 8 consecutive frames, the device generates an AU_LOP alarm (AU pointer is lost)
Regarding the description of replacing the main control board, which is wrong?
- A . The BD_STATUS and COMMUN_FAIL alarms will be reported when the main control board is removed and inserted. After the new board goes online, these alarms need to be cleared manually.
- B . If the software version carried on the replaced main control board is higher than the device version, you need to clear the main control library first, and then downgrade the main board software to the same version as the device.
- C . If the software version locked on the replaced main control board is lower than the device version, you need to upgrade the software on the main control board to the same version as the device
- D . When the main control board has 1+1 hot backup, under normal switching conditions, the replacement of the main control board will not affect the business.
The following statement about the alarm reversal function, which is wrong?
- A . For ports that have not opened services, alarm reversal is used to avoid related alarms
- B . By default, it is non-reverse mode. In this mode, the alarm of the device port cannot be reversed.
- C . In automatic recovery mode, regardless of whether the port currently has an alarm or not, the port device alarm can be reversed
- D . After the port device alarm is reversed, no alarm is reported when there is an actual alarm, and an alarm is reported when there is no actual alarm.
The key to NG WDM system fault location is to accurately locate the fault to a single station.
- A . TRUE
- B . FALSE
"Loopback method" includes the following four steps: 1. Loopback business channel sampling; 2. Draw a business path diagram; 3. Loopback section by section to locate the faulty site; 4. Preliminarily set as a single board problem. The correct order of the above four steps is?
- A . 1234
- B . 3124
- C . 2143
- D . 2134
The following description about the composition of the SOM system, which is wrong?
- A . The intelligent management software SOM is integrated on the U2000.
- B . The SOM system is composed of a hardware part and a software part.
- C . Spectral analysis type single board, optical amplification single board, used to obtain optical performance data, and conduct ongoing monitoring of optical signals without interrupting business.
- D . The software part completes real-time monitoring and real-time reporting of the optical performance of the network, and performs related adjustment operations.
The optical fiber quality detection light of the TNF1AST4 board shares the light source with the OSC channel. When the TNF1AST4 board is used for detection in the "advanced parameter mode" (), the OSC communication will be interrupted. At this time, only the fiber quality detection signal is sent, and the detection dynamic range is large.
- A . Online mode
- B . Typical model
- C . Normal mode
- D . Offline mode
