2. Introduction
Ascentac OPM110 Series, Optical Power Meter, is widely with 7 wavelength
selections, including 85onm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm & 1650nm.
The dynamic range from +26 to -50 dBm or +6 to -70 dBm provides high accuracy for
optical power measurement in fiber-optic networks. It can be used for absolute and
relative optical power measurement.
Ascentac OPM110 Series has built-in visual fault locator (VFL) and features excellent
mobility owing to its mini-size and light weight. It can be powered by dry batteries. Its
low power consumption and auto shutdown function allow extended operation in
the field.
The high resolution OLED display makes measured values read easily. The interface
with clearly labeled and intuitive key pad is easy for use. What‘s even better is that
Ascentac OPM110 Series is fairly budget-friendly.
