How important is the mechanical reliability of fiber connectors?
From the article “How to judge the quality of fiber optic connectors”, we can know that the quality of fiber connector depends on insertion loss, return loss, plug-in and pull-out times, fiber end face 3D parameters, mechanical reliability, etc. According to statistical surveys, mechanical factors cause up to 68% of fiber link failures, far exceeding the impact of […]
What Is Fiber Optic Cable?
Optical fiber cable is a type of communication cable. It uses one or more optical fibers in a protective covering to transmit information. We can use optical fiber cables alone or in groups to meet specific performance requirements. Fiber cables are mainly composed of optical fibers (glass fibers as thin as hair), plastic protective sleeves, […]
What causes attenuation of the FTTH drop cable?
The main reasons for ONU weak light are two aspects: equipment reasons and excessive attenuation of ODN link. Because equipment issues are easy to detect and eliminate them from the network management system in time, so now ONU weak light is mainly caused by excessive attenuation. The ODN link is divided into 4 sections, including backbone, distribution, introduction, and household. Which section is most likely to cause excessive […]
ODN Optical Distribution Network Structure
ODN Optical cable lines from the business convergence point to the users are mainly divided into 4 sections: backbone, wiring/distribution, introduction, and home segment, as shown in Figure 1. These fiber optic cable lines are aggregated on a plane (communications pipe or communication pole) to form a complex network. […]
