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.
Key Features:
Plug-and-Play Ethernet Interface: Simplifies connectivity and integration.
High-Speed Data Transmission & Analysis: Ensures rapid and efficient processing.
RS-232 Serial Interface Configuration The serial interface is primarily utilized for IP address queries and low-rate data communication. The default baud rate is 460800 bps, which can be modified via software commands.

If we integrate your OTDR module into our own monitoring system via software, can you provide the complete API/SDK?
Yes, we are highly supportive of system integration, and we offer a much more flexible solution than a standard SDK. We can provide our underlying TCP/IP communication protocol along with the 16-bit Hexadecimal (Hex) control command codes. This means your developers can ignore any operating system dependencies or specific library constraints. Whether your monitoring system runs on Linux, Windows, or an embedded RTOS, your software can directly communicate with and control our OTDR hardware by sending standard network sockets. We will provide the protocol documentation detailing how to trigger a scan, set pulse widths, and retrieve the raw data stream.
