The sea breeze is cool, the beer is fragrant, and as the Qingdao International Beer Festival is in full swing, the entire city of Qingdao is also immersed in the festive atmosphere. At the time when the city toasted to share joy, the 2018 Haier Whole House Water Purification Solution Interaction Conference was also held in Qingdao on July 27. At the meeting, Haier Water Purification put forward a new positioning centered on the integration of “experience, design, sales and serviceâ€, and announced the full-scale resource support and equity protection strategy for the whole house service providers to promote the whole house water purification. In the domestic market, it has been widely popularized and quickly established a benign ecology of mutual benefit and win-win between brands and dealers. Accurately grasp the pain points of users to create customized solutions As we all know, drinking water safety has always been the focus of attention. Dr. Martin Fox, a famous American water expert and nutritionist, once pointed out in "Healthy Water": "The volatile chemicals (such as residual chlorine) that the whole body is responsible for can be roughly divided into: 1/3 oral intake, 2 /3 Ingestion through the skin and respiratory tract during washing or bathing." The human body's multi-channel intake of harmful substances determines the purification of drinking water in the whole house. As the leading brand in the domestic water purification industry, Haier Water Purification has tailored the wisdom of the whole house to the user's pain points, showing the core advantages of health, wisdom and service specialization. According to the user's water habits and water quality, Haier Water Purification is a scientific and rational combination of complete water purification products, which can achieve full water purification of direct drinking, washing, bathing, cooking, washing vegetables and sanitation. In addition to ensuring the health and safety of drinking water, it can also effectively solve the life problems caused by heavy metals, residual chlorine and hard water, such as preventing the car from being scratched by sand in the water; effectively solving the scaling of wading equipment such as floor heating, washing machines and showerheads. Blocking problems and prolonging the service life; soft water can better care for the skin, resist dryness, and keep the clothes bright and soft for a long time. At the same time, based on personalized customization scenarios, Haier Water Purification also integrates IOT IoT, cloud platform and big data analysis to provide users with intelligent water quality monitoring, filter reminder and other intelligent experiences, and can actively contact according to big data feedback. Users, provide replacement filter, regular maintenance and other services. The “Net Water Gate Service Engineer Qualification Certification Standard†and “The Whole House Water Purification System Design, Equipment Installation and Maintenance Service Standardâ€, which was developed by Haier Water Purification, effectively standardized the service and operation standards of the whole process. Solved the worries of users using the whole house water purification. Four-in-one strategic upgrade focuses on user experience to create "4S service provider" At the meeting, Haier Water Purification put forward a new positioning of “Full House 4S Service Provider†for national service providers, and explained the differentiated brand strategy of Haier's whole house water purification from four aspects of experience, design, sales and service. In terms of experience, Haier Water Purification will further broaden the user channels and deepen the user's awareness of the whole house's clean water through the interactive experience of the scene; design, through professional team building and systematic personnel development, comprehensively enhance the team's professional design. Level; in sales, deep-seated interactions between the community and the user groups across the country, and joint cross-border alliances with well-known home improvement brands to enhance the comprehensive strength of the brand; service, promote the integration of sales and service, to be on call, press Approximately delivery, delivery synchronization, to provide users with the best service experience throughout the process. Multi-interest protection helps whole-house service providers detonate clean water market In order to help service providers to grasp the market opportunities of the whole house water purification and quickly seize market share, Haier Water Purification also announced a series of whole-house service provider resource support strategies at the conference site, on the one hand, unified brand authorization for service providers, and Building a unique retail area; on the other hand, providing rich resource support for service providers to help build stores quickly. It can be said that Haier Water Purification, a new service provider positioning strategy and a series of rights protection policies, has greatly reduced the pressure on service providers and channel expansion. The current water purification market has entered the era of the Nuggets driven by the consumption upgrade. Haier Water Purification has risen strongly in the industry with excellent quality, innovative technology and professional services. It not only optimizes the water purification experience based on user needs, but also cares about the service. The principle of business has paved the way for the whole house water purification products to penetrate the domestic water purification market in advance through various innovations such as interactive marketing and cross-border cooperation, which provided a strong driving force for the further development of the water purification market.

1. ONU with time slot drift
This kind of failure is usually caused by the aging of the laser and the drift of the time slot for the upstream data transmission of the ONU. It is also possible that an error occurs in the data of the bandwidth map sent by the downstream OLT, which causes an error in the transmission time slot of the ONU. This kind of faulty ONU is difficult to detect. Generally, the OLT needs to monitor the upstream data of the ONU in real time. Determine whether it sends data in the time slot allocated by the OLT. For this type of abnormally luminous ONU, because it mainly affects two adjacent ONUs, in addition to isolation, the protection bandwidth between time slots can also be increased to alleviate its impact on other ONUs.
2. Long light ONU
This failure is caused by the ONU's laser for a long time. As a result, the ONUs under the entire PON port cannot communicate normally. If the ONU emits strong light, the abnormal light emission of the ONU can be determined by testing the optical power at the optical splitter during troubleshooting. However, if it is a weakly emitting ONU, the judgment will be more difficult, and the abnormal light emission of the ONU cannot be measured at the optical splitter. Only through the intervention of the OLT and the use of specific detection algorithms can the abnormal ONU be judged. Usually, the business under the entire PON port will be affected, but because of its failure phenomenon has always existed, it has brought convenience to the troubleshooting to a certain extent.
3. Intermittent glow
The judgment of this kind of failure is the most difficult and irregular. It is also the biggest fault in the current network that accounts for the abnormally luminous 0NU. It is not only impossible to measure the abnormal light emission of the ONU at the beam splitter. In addition, it is necessary to observe and monitor faulty PON ports for a long time, which brings great challenges to network maintenance.
There are many fault phenomena in the network of abnormally luminous ONUs. There is no complete mechanism and process in the industry to solve this fault. Other operators have no controllable experience. In the operation of the actual network. The author summarized a set of procedures and experience for troubleshooting abnormal light-emitting ONUs. Can effectively solve most of the existing network failures.
cause of issue
1. Long light-emitting problem: The photoelectric converter is connected to the branch fiber by mistake, and the photoelectric converter emits light for a long time; the ONU optical module has an abnormal shutdown signal. Cause the ONU to emit light for a long time.
2. Coverage interference problem: For some reasons (such as insufficient extinction ratio), individual ONUs emit light in unlicensed time slots, which affects the normal services of other ONUs.
3. Overlapping interference problem: The inconsistency of the parameters of different ONU optical modules causes partial overlap of the upstream optical signals, which affects each other's services.
