5.1 OTDR Functions
5.1.1 iOLA (Hawkeye)
iOLA is an OTDR-based application designed to simplify the testing process. It automatically configures parameters, analyzes, and interprets complex OTDR curves. It uses an advanced algorithm to dynamically define test parameters and determine appropriate curve acquisition times based on the measured network. Multiple pulse widths at various wavelengths can be correlated to locate and identify faults with high resolution.

5.1.2 Pass & Fail Analysis
The device can automatically perform Pass/Fail judgments for each event based on pre-specified thresholds. Measurement results are displayed clearly on the screen.

5.1.3 Multi-Trace Analysis
The QX65 allows viewing and comprehensive analysis of up to 4 traces simultaneously, providing more accurate results for complex fiber networks.

5.1.4 Splitter Test
The device supports testing of three-level splitters, up to a ratio of 1:128.
Figure 10: Splitter test capability illustration.
5.1.5 Bidirectional Testing
Bidirectional testing averages values obtained from opposite directions, providing more accurate quantification of losses and improving test integrity in long-distance applications.
Figure 11: Bidirectional testing interface.
5.1.6 Jumper Test
Perform short-distance testing to accurately detect fiber events and losses in jumper cables.

5.1.7 PDF Report Generation
The QX65 includes built-in post-processing software to quickly generate test reports in PDF format.

5.2 Built-in Modules
5.2.1 OPM (Optical Power Meter)
The OPM module is used to measure the absolute optical power or the relative loss of optical power through a section of fiber link.
5.2.2 SLS (Stabilized Light Source)
The SLS module outputs a stable continuous signal, which is used in combination with an OPM to measure optical loss in fiber optic systems.
5.2.3 VFL (Visual Fault Locator)
The VFL module provides luminous stability, a strong light source, and strong penetration. It offers two light source modes: steady on and flashing, for visual fault identification.
Figure 14: User interfaces for OPM, SLS, and VFL modules.
5.2.4 RJ45 Network Test Module
This module supports network sequencing, network ranging, and optional network hunting for CAT5 and CAT6 cables.
5.2.5 FIP (Fiber Connector Inspection Module)
The FIP module visualizes the surface of the fiber connector. When combined with an optional handle probe, it can automatically analyze scratches and dust, save surface images, judge results (Pass/Fail), and generate a PDF report.
