QuestionQ2

Comprehensive AI Experiment

Which of these statements regarding the TNB1ELOM board is false?

  • A The ELOM board supports 10G pass-through capability and 20G service grooming capability.
  • B Functioning as an enhanced 8-port multi-rate wavelength conversion board, the ELOM board performs conversion between Any services and OTU2(e) services.
  • C The output optical signals on the WDM side are tunable within the C-band 80-wavelength range, and the channel spacing is 50 GHz.
  • D The board supports ODU0 non-convergence mode and ODU0 convergence mode.
Explanation

The board supports ODU0 non-convergence mode and ODU1 convergence mode. ODU0 convergence mode is not a supported operating mode; convergence at that level is specified as ODU1 convergence.

QuestionQ3

Huawei AI Computing Platform Atlas

The working and protection ports in a linear MSP group must reside on the same board.

  • A TRUE
  • B FALSE
Explanation

Working and protection ports for linear MSP do not have to be on the same board. Placing them on separate boards where possible improves protection against a board-level failure affecting both the working and protection paths.

QuestionQ4

AI Overview

Self-healing is a network’s ability to automatically restore its services within a short time after a fault, without manual intervention. Users are not aware of the network fault. A network with this capability is called a self-healing network.

  • A TRUE
  • B FALSE
Explanation

A self-healing network automatically recovers services after faults without requiring manual intervention, minimizing or eliminating users’ awareness of the disruption.

QuestionQ5

AI Overview

Which of the following fiber types has dispersion characteristics that meet this description? The dispersion at 1310 nm is 0, and the typical dispersion coefficient near 1550 nm is 17 ps/nm.km.

  • A G.653
  • B G.655
  • C G.654
  • D G.652
Explanation

ITU-T G.652 conventional single-mode fiber has a zero-dispersion wavelength around 1310 nm and a typical chromatic-dispersion coefficient of 17 ps/(nm·km) at 1550 nm.
