PID (Photonics Integrated Device) is an optoelectronic integrated device, PID single board can realize multi-wavelength integration, 40Km without optical amplifier, 80Km without dispersion compensation ()

• A.  TRUE
• B.  FALSE

Regarding the OSNR test of the OTN system, which of the following statements is correct? () (multiple choice)

• A.  When using OSA to test OSNR, because the noise in the signal band cannot be directly tested, the out-of-band noise interpolation method is adopted to calculate the noise in the band
• B.  OptiX OSN8800/6800 equipment MCA online test 100G wavelength OSNR also uses the shutdown method
• C.  The 40G and 100G wavelengths overlap due to the signal spectrum, and the OSNR value tested by the traditional OSA test method is low
• D.  After the wavelength signal passes through a filter device such as D40, the noise power between channels will be reduced, so the OSNR value of the traditional OSA test is higher
• E.  The integral method test OSNR is also called the turn-off method, and the channel business will be interrupted during the test. And in the case of a small number of waves, the OSNR value measured by the integral method has a certain deviation from the true value
• F.  The out-of-band noise interpolation method refers to inserting the noise of the instrument to replace the actual noise of the system

SOM is an intelligent optical layer management solution, which is only used for single-wave optical power and OSNR detection of coherent 40G and 100G systems

• A.  TRUE
• B.  FALSE

A certain network is configured with SOM. When performing path performance analysis, the OSNR value of the downstream optical amplifier of the OCh path is higher than that of the upstream optical amplifier. What is the error of the following analysis ()?

• A.  The calculation of the OSNR value of the first part of the OMS section where the OCH path is located is completed, and the calculation of the latter part has not been started. At this time, the performance analysis is started, and the new calculated value of the front part is reduced due to external reasons. This phenomenon will occur
• B.  The network management must issue the SOM routing configuration to the OMS segment on the path in order from the front to the back. It takes about a few seconds to issue the SOM routing configuration for each OMS segment, and it takes a few seconds to configure the SOM routing existence time between each OMS segment. difference
• C.  After the initial configuration of the SOM route is issued, the performance analysis is started immediately. If the SOM route is configured first in the OMS section at this time, the OSNR calculation is started first, and there is no basis for the previous OSNR calculation value, this phenomenon will occur
• D.  Click "Analyze" on the "Path Performance Analysis" interface to restart the performance analysis to solve the problem

The following steps add pointers

• A.  TUG3 to VC4 process
• B.  TUG2 to TUG3 process
• C.  VC-3 to TU-3 process
• D.  C-12 to VC-12 process
