The PON-55 is a reliable passive optical network (PON) power meter designed for BPON, EPON, and GPON systems with APC connectors. It enables live testing with OLT equipment and is ideal for FTTx/PON service turn-up and maintenance. The device can simultaneously measure signal power for voice, data, and video connections across multiple wavelengths, including 1310nm upstream burst signals and 1490/1550nm downstream signals. It features LED indicators for quick status assessment, supports data transfer via USB (with storage for up to 1,000 measurements), and includes adapters for easy connection to various fiber connectors. The meter is fitted with a shatter-resistant sleeve for durability, and optional auto-off enhances battery life. Included accessories comprise adapters, a carrying case, instruction manual, mini USB cable, and batteries. Software is provided to set thresholds, transfer data, and calibrate wavelengths.
