The HT6800-OTDR is a high-performance Optical Time Domain Reflectometer monitoring card for the HT6800 DCI DWDM Optical Transmission System. Providing 24/7 automatic fiber monitoring across 8 ports with up to 130 km detection range and ≥36 dB dynamic range, it delivers real-time fault detection, location, and alarm reporting. Supports online monitoring and GIS-based test result display. Occupies 1 slot.
OTDR dynamic range exceeding 36 dB enables detection of weak reflections over long fiber spans, supporting cable monitoring up to 130 km.
Supports 8 or 12-direction fiber optic polling monitoring via 8 independent LC ports (O1–O8), enabling multi-span network coverage in a single slot.
Provides continuous real-time fiber monitoring with automatic fault detection, alarm reporting, and location accuracy of ≤20 m without interrupting traffic.
Supports operating wavelengths of 1510 nm and 1625 nm (±10 nm), covering both standard and out-of-band OTDR measurement requirements.
Supports displaying test line results on GIS mapping interface and saving test results for historical analysis, enabling visual network asset management.
Loss detection accuracy ±0.5 dB, distance accuracy ≤20 m, event blind spot ≤10 m, and attenuation blind spot ≤20 m for precise fault location.
