NEW QUESTION # 33
Which of the following technologies is used by GPON system to allocate bandwidth to ONU?
- A. WDM
- B. T-CONT
- C. DBA
- D. Type B
Answer: C
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.

NEW QUESTION # 44
What is the minimum number of chassis to deploy an 8x200G (2x100GE) WDM system with DC908?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
The correct answer is1. TheOptiXtrans DC908is designed to support high-density configurations, allowing an
8x200G (2x100GE)WDM system to be deployed using justone chassis.
Here's a breakdown of how this is achieved:
* High Integration:The DC908 integrates multiple components, such as optical modules, amplifiers, and control units, into a single compact2U chassis. This eliminates the need for additional hardware or external devices.
* Scalability:The DC908 supports up to8 wavelengths per fiber pair, each operating at200G. This means that all 8x200G channels can be accommodated within a single device.
* Service Aggregation:Each 200G wavelength can carry multiple 100GE services, enablingefficient aggregation of traffic. For example, two 100GE services can be mapped onto a single 200G wavelength.
* Space Efficiency:By consolidating everything into one chassis, the DC908 minimizes rack space requirements, making it ideal for data centers and edge locations where space is limited.
Other options:
* 2, 3, or 4 chassis:These would only be necessary for extremely large-scale deployments or if additional redundancy were required. However, for an 8x200G system, a single chassis is sufficient.
This compact design highlights the DC908's efficiency and cost-effectiveness for modern optical networks.
