Developed by FirstFiber Technologies, the Modular Kernel OTDR integrates core functional components including optical interfaces and data processing units. It exposes an external Ethernet interface to facilitate seamless secondary development, alongside a serial port designed for basic control operations such as status monitoring and module parameter configuration.
Featuring a compact, cost-effective, convenient, and highly efficient design, this module is engineered to precisely pinpoint real-time fault conditions across the entire optical fiber link. It is widely applicable to fiber deployment, routine maintenance, field operations, and failure analysis.
Operating Principle
The module operates by connecting to a host computer (PC or embedded system) via Ethernet. The host computer manages the entire workflow simply by issuing measurement commands to the OTDR module and receiving the returned data.
Secondary Development & Integration
Supporting user-defined secondary development, this module enables users to rapidly prototype their own professional OTDR instruments or optical fiber online monitoring systems. By only requiring the development of the human-machine interface (HUI/GUI), users can significantly shorten the OTDR R&D cycle. Additionally, the module can be effortlessly embedded into other optical communication equipment or systems to provide integrated OTDR functionality.
