With the rapid development of data centers, cloud computing, and other technologies, the demand for Multi-Fiber Push-On (MPO) cables has also shown rapid growth. However, during on-site testing, traditional single-channel optical power meter verification tests are time-consuming, labor-intensive, and have low reliability. The MPO optical power meter is used for fiber optic network installation, project acceptance, and maintenance. It can test information such as insertion loss of MPO cables with a single click and integrates functions such as data storage, threshold analysis, and data export. The testing efficiency is more than 10 times higher than that of traditional instruments, making it suitable for on-site applications such as MPO equipment room testing, production line verification, and polarity judgment.
