HCIP 2.3

Which of the following terms has the meaning that "the wavelength carrying local services can be transmitted to any direction"?

• Directioned

• Directionless

• Colored

• Colorless

During coherent system commissioning, the optical power of each wavelength is obtained by an OPM8 board or an optical spectrum analyzer. The optical power difference for all wavelengths needs to be adjusted to the ( ) range at an equalization site.

• -1 dB

• +-2 dB

• +-3 dB

• +-4 dB

In a 40-wavelength system, a DAP board (TN15OAC106) is used, the total input optical power ranges from -16 dBm to 4 dBm, and the typical gain is 16 dB. What is the nominal single-wavelength output optical power?

• 0 dBm

• 1 dBm

• 4 dBm

• 5 dBm

Which of the following boards does not provide any MON port for online optical signal detection?

• OAU1

• WSMD4

• TTA

• FIU

Which of the following statements about optical line protection is false?

• OLP board switching is related only to the receive optical power.

• Optical line protection implements dual-ended switching. Therefore, inconsistency between the receive and transmit routes will never occur if a single fiber is broken.

• Optical line protection protects line fibers between adjacent sites using the dual fed and selective receiving function of OLP boards.

• When an OLP board is used to configure optical line protection, the RI1/TO1 port on the OLP board must be working and the RI2/TO2 port must be protection.

Which of the following are common test instruments in a transmission system?

• Optical power meter

• SDH tester

• SmartBits tester

• Optical spectrum analyzer

Which of the following statements about switching conditions and configurations in the PW FPS scenario are true?

• The switching condition depends on the OAM status of the working or protection path.

• The switching condition depends on the status of the APS protocol.

• PW FPS must be configured symmetrically (configured at both ends).

• PW FPS can be configured asymmetrically (configured at one end but not configured at the other end).

Which of the following are FEC types?

• FEC

• HFEC

• AFEC

• SDFEC

In an NG WDM system, there are many factors that affect the transmission distance. Which of the following affect the transmission distance of service signals?

• Optical line loss

• Optical line dispersion

• Non-linear effect of optical fibers

• Using the optical supervisory channel (OSC)

Inter-board cross-connections refer to the cross-connections configured between different boards. On the NMS, inter-board cross-connections can be configured between what boards?

• OTU and OTU

• TU and LU

• TU and TU

• LU and LU
