NEW QUESTION # 37
Which of the following technologies is used by GPON system to allocate bandwidth to ONU?
- A. Type B
- B. T-CONT
- C. WDM
- D. DBA
Answer: D
Explanation:
The correct answer isDBA (Dynamic Bandwidth Allocation). DBA is a critical technology in GPON systems that dynamically allocates upstream bandwidth to Optical Network Units (ONUs) based on their real- time traffic demands. This ensures efficient utilization of the available bandwidth and prevents congestion in the upstream direction.
* T-CONT (Traffic Container):While T-CONT is used to classify and manage different types of traffic (e.g., voice, video, data), it is not responsible for bandwidth allocation.
* WDM (Wavelength Division Multiplexing):WDM is a technology used in optical networks to transmit multiple signals over a single fiber using different wavelengths. It is unrelated to bandwidth allocation in GPON.
* Type B:Refers to a protection mechanism in GPON, not bandwidth allocation.
