FOTAS D-50 is a fiber optic distributed acoustic sensing system that
can be used easily in different situations. D-50 keeps your fences and
borders safe and sends early warnings of threats. It is one of the
proven early systems for security. FOTAS detects third-party
intervention, illegal crossing attempts, and unauthorized excavations
along a line spanning several kilometers to thousands of kilometers.
D-50 has two channels which makes this system cut-resilient.
| Fiber Optic Cable | Single-mode fiber optic cable |
| Detection Channels | Two fiber channels of simultaneous real-time independent intrusion detection per device |
| Detection Distance | 50 km |
| Sensing Technology | Coherent Optical Time Domain Reflectometer (COTDR) |
| Artificial Intelligence | Deep-learning-based intrusion detection algorithms optimize sensitivity and probability of detection. Locations can be changed with parameters to avoid nuisance alarms. Different algorithms exist for buried and fence applications. The system is hybridsince both are applicable |
| System Interface | Web 2.0 |
| Sensor Sections | Software configurable, independent sensor sections (detection zones) |
| Temperature Range | Sensing Cable: -40~70 °C / D-50 Device: 0~40 °C (AC environment) |
| Power Supply | 110 to 240 Vac, 47 to 63 Hz, auto ranging |
| Dimensions / Rack -Clearance / Weight | 49 cm (19”) x 50 cm x 8.9 cm(2U) |
| Laser Safety Class | Class 1 (IEC 60825-1, 21CFR1040.10), shutoff: key switch on front panel |
| Regulatory Certification | ISO9001 accredited design and manufacturing is CE certified (Electromagnetic compatibility Directive (EMC) 2014/30/EU (EN 55032:2015 Class A, EN IEC 61000-3-2:2019+A1:2019, EN 61000-3-3:2013+A1:2019, EN 55035:2017+A1:2020,EN 61000-4-2:2009, EN 61000-4-3:2020, EN 61000-4-4:2012, EN 61000-4-5:2014+A1:2017, EN 61000-4-6:2014, EN 61000-4-8:2010,EN 61000-4-11:2020), The low voltage directive (LVD) (2014/35/EU), (IEC 62368-1:2018, EN IEC 62368-1:2020 + A11:2020) |
