Key Features

INNO Instrument MINI 2: Optical time domain reflectometer

OTDR (Optical Time Domain Reflectometer)

OTDR mode is adopted to measure distance, loss, reflectivity, attenuation and accumulation loss on a fiber optic link.

INNO Instrument MINI 2: Smart optical link analyzer SOLA

SOLA (Smart Optical Link Analyzer)

SOLA is an application for the OTDR, designed to simplify the OTDR test process without the need to configure parameters or analysis while parsing multiple complex OTDR curves.

Inno Instrument MINI 2: VFL / Visual fault locator

VFL (Visual Fault Locator)

VFL can be used to find direct defect locations in dead zones of fiber testing or to calibrate the fiber core in multi-fiber cables.

Fiber microscope

Fiber end tester (peripheral required) is mainly used to test the cleanliness and flatness of the fiber end-face.

APC connector

To improve test efficiency and optimize the OTDR function, it is recommended to use the APC connector and plug it to the MINI 2 SM port, due to the low reflectance it causes. The reflection coefficient is the key parameter that will affect OTDR performance and particularly the dead zone (APC connector performance is better than UPC connector performance).
