OTDR 980TEK

Isolating faults on live PON networks without interrupting active subscribers requires robust out-of-band optical filtering. We deployed the 980TEK-A24 (1625 nm) and 980TEK-B24 (1650 nm) units across our maintenance teams, allowing non-disruptive testing on live lines carrying 1310/1490/1550/1577 nm signals at power levels under 0 to 5 dBm. Technicians appreciate the modern Android-based multi-touch UI, which makes navigating settings and zooming into events on spans up to 100 km fast and responsive. The integrated Event Map feature automatically identifies splices, connectors, and macrobends without requiring manual backscatter curve interpretation, significantly speeding up field troubleshooting.

Equipping field crews with separate optical power meters, light sources, visual fault locators, and Ethernet cable testers increases tool bag weight and field delay. The 980TEK OTDR combines 9 functions into a single 0.85 kg compact chassis, integrating an OTDR, Event Map, OPM, OLS, VFL, RJ45 sequence/tracker modules, LED work light, and wireless Bluetooth connectivity. Technicians can complete fiber and copper drop validation at subscriber premises and wirelessly export test reports via the phone application on-site. The turnkey package includes a carrying case, TF card, OTDRviewer PC software, USB cord, power adapter, and calibration certificate right out of the box.

Scaling test equipment across subcontracted installer teams requires finding an optimal balance between dynamic range performance, field durability, and budget. At a reference price of $290, the 980TEK delivers 26/24 dB dynamic range (on the dual-wavelength 980TEK-D26 model) along with FirstFiber’s 100% free Light Customization service for 20-unit MOQ orders. We customized our order with localized boot screens, corporate logo placement, custom model numbers, and language menu options. Dispatched via DHL Air Express within 3 to 7 days, this unit represents an outstanding procurement choice for B2B fleet standardization.
