The statement isFalse. While theOptiXtrans E9600andOSN 1800are part of Huawei's optical transmission portfolio, the1X908andE5800are not included under the OptiXtrans product line.
Here's a clarification:
* OptiXtrans E9600:A series of optical transmission devices designed for backbone, metro, and access networks.
* OSN 1800:A compact optical transport platform for enterprise and carrier-grade applications.
* 1X908:This is not a recognized product in Huawei's optical transmission portfolio.
* E5800:Refers to a different product line, typically associated with access networks rather than optical transmission.
The confusion may arise from overlapping product names, but the OptiXtrans series specifically focuses on optical transmission solutions.
NEW QUESTION # 22
OptiXtrans DC908 product is usually used in backbone long-distance networks.
- A. True
- B. False
Answer: B
Explanation:
TheOptiXtrans DC908is specifically designed fordata center interconnect (DCI)applications, not backbone long-distance networks. Its primary use cases include:
* Connecting geographically distributed data centers for cloud services, disaster recovery, and load balancing.
* Supporting short-reach, high-capacity links (e.g., metropolitan areas) rather than ultra-long-haul backbone networks.
For long-distance backbone networks, Huawei offers other products like theOptiXtrans E9600 seriesorOSN
9800 series, which are optimized for higher capacities and longer distances.
