The NetPeppers SpicyONE is a TIER 1 app-controlled singlemode fiber optic certifier that sets new standards in fiber optic measurement technology. Certify fiber optic cabling in accordance with ISO/IEC 11801/14763-3, DIN EN 50173-1, TIA-568.3 and IEEE 8802-3. As the world's first completely app-controlled certifier, it is operated via the free NP-Connect app on Android and iOS. The standard-compliant light source at 1310 and 1550 nm delivers stability of only +/- 0.02 dB per 15 min. Supports single, two and three jumper configurations, loopback and dual-ended measurements in simplex or duplex mode. Records attenuation, fiber length, propagation delay and polarity for each measurement and compares immediately against stored limit values. Built-in VFL for optical troubleshooting.
