A) FALSE
B) TRUE

2. The following about system OSNR commissioning errors are

A) The multiplexer is an M40V single board, "watching the receiving end, modulating the end", while ensuring that the optical power flatness meets the index requirements, the optical power flatness can be sacrificed to ensure the flatness of the OSNR (or BER)
B) One of the principles of the OSNR flatness commissioning of the MPI-R point system: After the pump power is determined, the OSNR flatness of the MPI-R point is detected by a spectrometer, if the OSNR flatness is not up to standard (OSNR flatness index ≤ 2dB) , You need to adjust M40V
C) APE automatically adjusts the optical power of each channel to ensure that the optical power of the receiving end is flat, thereby ensuring a flat OSNR
D) Adjust the single-wave flatness first, and then adjust the optical power of the main line

A) The maximum management capability of the SDH network element manager subsystem is 2500 equivalent network elements, so 1 SDH network element manager instance needs to be deployed; the maximum management capability of the router network element manager subsystem is 5000 equivalent network elements Yuan, so you need to deploy 1 instance of the router network element manager
B) Due to the purchase of SDH end-to-end and WDM end-to-end value-added features, it is necessary to install the SDH network management subsystem and OTN network management subsystem; as the Corba northbound interface is purchased, the Corba northbound subsystem needs to be installed
C) Since there are SDH, OTN and router series network elements, it is necessary to install SDH network element manager, OTN network element manager and router network element manager subsystem
D) If the OTN series network element is OSN 6800+OSN 8800T32 (without ASON, the ratio of the two is 1: 1), where OSN 6800 is the master subrack and OSN 8800 is the slave subrack.
