The NetPeppers SpicyONE QUAD is a TIER 1 app-controlled quad-wavelength fiber optic certifier covering both singlemode and multimode fiber in a single kit. Certify fiber optic cabling in accordance with ISO/IEC 11801/14763-3, DIN EN 50173-1, TIA-568.3 and IEEE 8802-3. Completely app-controlled via the free NP-Connect app on Android and iOS. Includes Encircled Flux (EF)-compliant light sources at 850/1300 nm (MM) and 1310/1550 nm (SM), all with 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 per measurement and compares immediately against stored limit values. Built-in VFL for optical troubleshooting.
