What is the maximum single-fiber capacity of OSN9800?
- A. 16T
- B. 24T
- C. 19.2T
- D. 48T
Answer: D
Explanation:
The correct answer is48T. TheHuawei OSN 9800series supports a maximum single-fiber capacity of48 Tbps
, making it one of the most advanced optical transport platforms available.
Key factors contributing to this high capacity include:
* WDM (Wavelength Division Multiplexing):Combines multiple wavelengths on a single fiber, each carrying data at speeds up to 400G or higher.
* OTN (Optical Transport Network):Provides efficient framing and multiplexing, enabling high- density traffic aggregation.
* Advanced Modulation Techniques:Uses techniques like QPSK (Quadrature Phase Shift Keying) and QAM (Quadrature Amplitude Modulation) to maximize spectral efficiency.
This level of capacity is critical for backbone and core networks, where large volumes of data need to be transmitted over long distances without bottlenecks.
NEW QUESTION # 22
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 # 23

NEW QUESTION # 26
What is the downstream bitrate of the GPON standard?
- A. 2.5 Gbps
- B. 2 Gbps
- C. 1 Gbps
- D. 10 Gbps
Answer: A
Explanation:
TheGPON (Gigabit Passive Optical Network)standard, defined by the ITU-T G.984 specification, supports asymmetric data rates for upstream and downstream traffic. Specifically:
* Downstream Bitrate:2.5 Gbps
* Upstream Bitrate:1.25 Gbps
The higher downstream bitrate reflects the typical usage pattern of internet services, where users consume more data (e.g., streaming videos) than they upload. GPON uses Time Division Multiplexing (TDM) to manage data transmission between the OLT and multiple ONUs.
For higher bandwidth requirements, advanced standards like XG-PON (10 Gbps downstream) or NG-PON2 (multi-wavelength support) are available.

NEW QUESTION # 27
Which of the following statements about MS-OTN are correct?
- A. MS-OTN is short for Multi-Service Optical Transport Network.
- B. MS-OTN supports ODUk cross-connections.
- C. MS-OTN supports SDH, PKT, and OTN services.
- D. OSN 1800V, 1800II E, and 1800I E all can support MS-OTN.
Answer: A,B,C
Explanation:
The correct answers areA, B, and C. Here's a detailed explanation of each statement:
* A. MS-OTN is short for Multi-Service Optical Transport Network:This is correct.MS-OTN integrates multiple technologies (e.g., OTN, SDH, Ethernet) into a single platform, enabling converged transport for diverse services.
* B. MS-OTN supports SDH, PKT, and OTN services:This is correct. MS-OTN supportsSDH (Synchronous Digital Hierarchy)for legacy services,PKT (Packet)for Ethernet-based traffic, and OTN (Optical Transport Network)for high-capacity transport.
* C. MS-OTN supports ODUk cross-connections:This is correct. MS-OTN leveragesODUk (Optical Channel Data Unit-k)cross-connections to efficiently switch and route traffic at the optical layer, ensuring high performance and scalability.
* D. OSN 1800V, 1800II E, and 1800I E all can support MS-OTN:This is incorrect. While theOSN
1800Vand1800II Esupport MS-OTN, the1800I Eis a simpler device designed for access networks and does not fully support MS-OTN capabilities.
