The impact of ONU weak light on network speed
ONU is what we commonly call “optical modem”. ONU weak light refers to the phenomenon that the optical power received by ONU is less than the ONU receiving sensitivity. The receiving sensitivity of ONU refers to the minimum optical power that ONU can receive when it is working normally. Usually, the receiving sensitivity index of […]
Causes and Countermeasures of ONU Weak Light
At present, the phenomenon of ONU ONT low light is very common. Nationally, ONU low light accounts for 30%, that is, out of 100 users, the ONUs of 30 users have low light. We summarized the low light situation in a certain province, as shown in the figure below. Although after 2 years of debugging […]
Survey of WiFi Network Speed in 39 Home Broadband Users
Currently, the contracted bandwidth of most home broadband users exceeds 100M. Although the contracted bandwidth of users is not low, their experience of internet speed is average. Due to the fact that most of the business of home broadband users is accessed through WiFi, the speed of indoor WiFi has become an important factor affecting […]
What are the main quality issues of home broadband?
As of the end of 2020, the penetration rate of household broadband in my country has reached 96%, and the market has become saturated. The competition focus of operators has shifted from user growth to quality improvement. Initially, operators were only responsible for broadband access (to optical modems ONU/ONT). With the development of services such […]
What are the common reasons that affect the quality of home broadband services?
Although about 60% of home broadband service quality problems occur in home networks (see the article “What are the main quality issues of home broadband?”, users thought all problems are caused by the operator’s network quality. So what is real? From the perspective of end-to-end connection, the operator’s home broadband network is mainly composed of broadband fiber access network, […]
Common GPON network problems and solutions
Common GPON network problems are mainly divided into several categories, including optical path failure, equipment hardware failure, ONU management abnormality, service performance problems and network protection failure. The following are specific analysis and treatment methods: Optical path failure (highest proportion) 1. Loss of optical signal (LOS/LOSi) Phenomenon: Trunk fiber break (LOS): OLT cannot receive optical signal, and […]
What is GPON?
GPON stands for Gigabit passive optical network, which is the latest generation of broadband passive optical integrated access standard based on ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. It is regarded by most operators as an ideal technology for realizing broadband and integrated transformation […]
