OTDR Basic for the measurement of single-mode (SM) 1310-1550 nm fibre optic links

Mini tester for fibre optic (OPM and VLF) and data cables

Optical power and data cable tester in a compact, sturdy, ergonomic and low power consumption format. It is used to verify the quality of connections in optical and data networks. It can measure the optical power (OPM) of multiple wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm and 1650nm. Additional features include a flashlight, Visual Fault Locator (VFL) and RJ45 UTP cable testing to verify the transmission of data signals.

This mini tester stands out for the integration of multiple functions in a small, easy-to-carry size. This makes it a really practical accessory for the installer, a versatile solution for several applications.
