Based on the optical time-domain reflectometer (OTDR), the advanced optical switch (OSW) and other plug-in modules developed on the telecom device platform of Accelink, OLM products are adaptable to the whole OSP series platforms, and support hot swap. The product forms include 1RU height OSP1200, 2RU height OSP2200 and 5RU height OSP5200. The optical time-domain reflection and AI big data processing technology are adopted to conduct the real-time status monitoring and fault positioning of optical cable network. Combined with the OScape comprehensive optical fiber quality analysis platform of Accelink, an optical fiber network product with the centralized monitoring system is constructed, integrating the functions of test, analysis, alarm, positioning, information management and business statement.
