Attention: Abnormal OSC Communication of the OptiX OSN 1800

The networking is as follows: Station A and station B are configured with the LWX2 and the DMD2S. Each SCC is configured with one 1551-nm optical module to implement the OSC communication. The configuration of the two stations is the same. The NE version is 5.67.1.22. After Huawei optical power commissioning is complete, the ECC between station A and station B fails.  1.       The optical power is incorrect. 2.       The optical module is faulty. 3.       The SCC software is defective The SCC software has a bug. When the PHY chip used by the OSC optical port on the SCC works in BASE-EFX mode, special requirements are raised for the optical module. That is, the chip can be linked only when the amplitude of the electrical input signals of the optical module is higher than 800 mV. The amplitude of the electrical input signals of the currently used optical module is about 800 mV. Therefore, the OSC communication may fail.

The LWX2 does not support the ESC. Station A and station B use the optical module on the SCC to implement the OSC communication. Check the receive optical power of the RM1/TM1 optical port on the SCC. The check result shows that the receive optical power is normal. There is no abnormal alarm. Run :cm-get-eccroute. The remote NE cannot be queried. Run :cm-get-bdinfo to query the DCC state. The query result shows that the DCC state is rx-f. Reset the SCC. The fault persists.

Install OptiX OSN 1800 A and OptiX OSN 1800 B in the same equipment room. Interconnect the RM1s/TM1s of the two OptiX OSN 1800s with the added fixed optical attenuators through fibers. Run :cm-get-eccroute. The remote NE still cannot be queried. The DCC state is still rx-f.

The confirmation result by the related experts shows that the SCC software has a bug. When the PHY chip used by the OSC optical port on the SCC works in BASE-EFX mode, special requirements are raised for the optical module. That is, the chip can be linked only when the amplitude of the electrical input signals of the optical module is higher than 800 mV. The amplitude of the electrical input signals of the currently used optical module is about 800 mV. Therefore, the OSC communication may fail.

Software mitigation is performed in the latest version (5.67.01.24). The problem is solved. After the NE software is upgraded to this version, the OSC communication is normal on Huawei WDMOSN 1800.

Interbrand top-100, Huawei becomes the first Chinese brand on the list

Interbrand released the 15th annual Best Global Brands on Oct. 9, and a Chinese company broke into the list for the first time throughout history.

Huawei, a Chinese telecommunications and transmssion network equipment manufacturer and the world's third largest smartphone provider was listed No. 94 and is one of five new entrants on the Best Global Brands ranking this year. Maybe Huawei is more of a household name in Asia than in Western markets, but it has got its popularity and reputation globally with its rapid growth and long-term investments and earned its place in this year' Best Global Brands ranking.

Focused on innovation and aggressive globalization, Huawei strategically utilizes its resources in accordance with market demand. Huawei is quickly becoming one of the world’s largest optical trasport equipment manufacturers with 65% of its revenue coming from outside of China. 

Proved its strategy is prosperous, this transnational networking and telecommunications company is rapidly becoming the market leader in Latin America and Central Asia, and a major player in Canada. With the new marketing approach--getting closer to more customers which is to support its ambitions, the brand has recently launched a more consumer-friendly face. Its work that cooperated with telecom operators around the world is being leveraged as a way to show how much impact Huawei has on the world they live in. with these customers in mind, Huawei plans to eliminate 80% of the low-cost Mobile device this year. The goal is to develop products to meet consumer demand, instead of meet the minimum costs and operational specifications. Huawei's star product line—Ascend is clearly shows that the company is trying to change their image in the Huawei optix market, transform low-cost alternatives into a more advanced one. With smart phone sales volume go up since the first quarter of 2014, and the current 20% global market share is in the best brands place, Huawei is at its full speed and making its mark to the world.
