2. Introduction
Ascentac OLM300 Series, Optical Loss Meter, combines optical light source (OLS),
optical power meter (OPM) and visual fault locator (VFL) in one handheld unit
which can conveniently perform optical power & link loss measurement and
troubleshooting of fiber-optic network. It is a perfect instrument for bi-directional
testing for both multi-mode and single-mode fibers.
Ascentac OLM300 Series characterizes remote wavelength-switching and
enables technicians to read remote measurement values. The fairly better
feature is to analyze cable status like macro-bending or low power and notify
technicians of the condition on screen.
Ascentac OLM300 Series can accommodate up to 1000 results and transfer data
to PC via USB connection. It is battery-operated by either dry batteries or
rechargeable batteries (4 AAA-size).

2.1 Feature
Auto-wavelength recognition and remote wavelength-switching
Automatically bidirectional loss test Readable remote measurement
values
Analysis of cable status e.g. Bending (Displayed on screen)
Document results and generate reports to PC via USB connection
Memory capacity of 1000 results
Auto shutdown & backlight sleep mode (Programmable)
(Extend the battery life)
