Ultra-long-distance compatible OTDR-based optical fiber communication link status monitoring device. Utilizing its features, it can also be applied to various sensing applications with abnormal event detection functionality!
ADTRAN's optical communication path monitor ALM (Advanced Link Monitor), formerly known as ADVA Optical Networking, can be introduced to existing operational optical fiber communication lines, enabling constant monitoring of their status and health with unprecedented ease, significantly reducing recovery time from line faults. If every time there is a communication line or network issue it requires field deployment to determine whether it is a communication equipment failure or a line fault, that is not ideal. With the introduction of ALM, real-time constant status monitoring can be achieved without increasing maintenance personnel or equipment, allowing for immediate fault determination regardless of the service or application type of the optical fiber communication path, leading to effective fault and failure recovery operations and reduced work time. Line faults can be quickly pinpointed and logged. Leveraging these features, it is also possible to apply the technology to various sensing applications such as intrusion detection and monitoring for critical facilities, flood detection for indoor and outdoor equipment, and temperature detection, for which dedicated sensor assembly parts are available. We also offer measurement software modules and data analysis services tailored to customer needs.

basic information
The measurement distance of ALM is up to 160 km. It can be applied to extensive optical communication lines from access to core, monitoring 16 to 64 lines of optical fiber per unit, using independent monitoring optical signals (wavelength: 1650 nm) that do not interfere with the service communication signal wavelength or traffic. It performs near real-time measurements using the OTDR method, allowing for tracing of optical fiber loss profile information due to faults and identification of the fault occurrence point (with a maximum resolution of 1 sampling per minute and a fault detection accuracy of 10 m). It is an all-in-one unit with a compact housing, embedded OS (Linux), and control software, achieving low power consumption (<10W) and a wide operating temperature range (-5°C to +55°C). The entire process is managed via SNMP, and by linking with FSP Network Manager and GIS (Geographic Information System) servers, it graphically and intuitively identifies the location of line faults.
