The agreement, signed Tuesday, June 17, aims to develop a resilient, high-capacity national backbone network to strengthen the country's digital transformation. Zimbabwe is advancing its fiber optic infrastructure through a new partnership between PowerTel Communications—a subsidiary of the national electricity company—and Paratus Zimbabwe. Its ability to provide high-speed internet without cables or towers made it very attractive, especially in rural areas where internet access has always been poor. The state of Zimbabwe's internet and mobile networks industry report for Q4 2024 is finally out! We get to see what the numbers and what the impact Starlink has been on Zimbabwe so far.

Insertion loss (often abbreviated as IL) mainly measures light lost between two fixed points in an optical fiber. In fiber optic communication, insertion loss and return loss are two important metrics for evaluating the quality of termination between some fiber optic devices, such as fiber connectors, fiber optic cables, pigtails and so on. Return Loss (also called Back Reflection) – The reflection of signal power, usually.
