QUESTION 90
The NG WDM two-dimensional ROADM site can use the WSMD9 single board, and its signal flow is an optical signal that is connected to the main optical channel from the “IN” optical port. The RDU (ROADM Demix Unit) optical module broadcasts nine identical optical signals, which are output from the “DM1~DM8” and “ECPO” optical ports respectively. One of the signals is localized by the splitter board, and the other eight signals are dispatched to the other eight directions. Each wave of the main optical channel is connected from the “EXPI” optical port. The multiplexed or single-wave optical signal that needs to be inserted locally is input through the “AM1″~”AM8” optical port.

QUESTION 91
The following description of the operation of the device, the error is:

QUESTION 92
In WDM systems, when using less than () wavelength, it is ideal to use a dielectric thin film filter (TFF).

QUESTION 93
MPLS APS is a network protection mechanism. It implements service switching by using the MPLS OAM detection function.

QUESTION 94
A, C are the WDM OTM stations, and B is the relay station. When the transmission direction of the A to B stations is interrupted, the Wavelength side of the B-stack OTU relay board reports the R_LOS emergency alarm and runs the processing to the upstream A.
The station side OTU2_BDI secondary alarm. At the same time, the alarm continues to be transmitted to the downstream station of the B station. After the alarm is processed at the C site, the ODU2_PM_AIS minor alarm is reported on the WDM side of the C-site OTU, and the ODU2_PM_BDI secondary alarm is transmitted back to the upstream station A.

QUESTION 95
Which of the following is not a precaution after board replacement?

QUESTION 96
The optical and electronic shelves of the OSN 9800 are connected through the master-slave subrack cascading mode and connected through the GE 1/2 port on the CTu board.
