NEW QUESTION # 28
Which of the following fiber types complies with the description that the dispersion at 1310 nm is 0 and the typical dispersion coefficient around 1550 nm is 17 ps/nm.km?
- A. G.655
- B. G.652
- C. G.653
- D. G.654
Answer: B
Explanation:
The fiber type described, having zero dispersion at 1310 nm and a typical dispersion coefficient of about 17 ps/(nm km) at 1550 nm, corresponds to ITU-T G.652 standard fiber, commonly called standard single-mode fiber (SSMF). G.652 fibers are widely used in optical networks due to their low attenuation and favorable dispersion characteristics around 1310 nm, where chromatic dispersion is minimal (essentially zero). This makes them suitable for legacy systems and many current applications. In contrast, G.654 is optimized for low loss and dispersion in the 1550 nm window; G.655 fibers have non-zero dispersion-shifted characteristics; G.653 fibers have zero dispersion around 1550 nm, which differs from the question's description. HCIP-Transmission standards specify G.652 as the standard fiber matching these parameters.

Which of the following are data dumping types on the NMS?
- A. Periodic dumping
- B. Manual dumping
- C. Overflow dumping
- D. Automatic dumping
Answer: A,B,C
Explanation:
Data dumping on Network Management Systems (NMS) can occur in several types: (A) Periodic dumping, where data is saved at set intervals for monitoring and analysis; (C) Overflow dumping, triggered when buffer capacity is exceeded; and (D) Manual dumping, initiated by user commands. (B) Automatic dumping is not a standard term here or is often encompassed within periodic or overflow dumping mechanisms. HCIP- Transmission references these types as part of NMS data handling and fault diagnosis strategies, enabling efficient network performance management and troubleshooting.
