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 […]
How the new optical splitter doubles the access capability of the Combo port?
Combo port resource usage status With the development of fixed gigabit services, XG-PON is gradually taking a dominant position in broadband access networks. In order to share ODN with GPON, XG-PON usually uses Combo optical modules (commonly known as “Combo ports”). Whether users use GPON ONU or XG-PON ONU, they can directly connect to the optical splitter […]
Fiber Patch Cord Types and Functions
According to different fiber types and transmission modes, fiber patch cables can be divided into two categories: Single Mode Fiber Optic Patch Cables and Multimode Fiber Optic Patch Cables. Single mode fiber patch cables are mainly use OS1 and OS2 fibers, generally are G.652D fiber, G.657A1 fiber, G.657A2 fiber, G.657B3 fiber, please refer to article “7 types of optical […]
Fiber Optic Splitter
Fiber optic splitter is an optical passive device used to realize the splitting and combining of optical signals. Fiber Splitter distributes the light energy which transmitted in one fiber to two or more fibers in a set ratio, or combines the light energy which transmitted in multiple fibers into a single fiber. PLC splitter is […]
What is PON?
PON is the main technology used for fiber optic broadband access. It has been 15 years since China Telecom began large-scale commercial use in 2006, but the application of PON technology has not declined at all. It is not only the main technology for fiber optic broadband access, but also gradually penetrating into private networks, […]
How to Improve XG-PON Resource Utilization of Combo User Board
This article discusses three solutions to improve the XG-PON resource utilization of the Combo user board. The solutions can be implemented independently or in combination. The implementation of the plan may involve the cooperation of multiple departments such as marketing, decoration and maintenance, and construction. The feasibility still needs to be tested in practice. Meet […]
What is XGS-PON, GPON and XG-PON?
In late October 2021, China Mobile launched a centralized procurement bidding for the new PON equipment from 2022 to 2023, and announced the winning results at the end of November. The tender package of this tender is divided into Bid 1 and Bid 2. Bid 1 is XG-PON equipment and Bid 2 is XGS-PON equipment. […]
