## Long description

The MikroTik QX43-S1 is an OTDR fiber tester for single-mode networks, offering a 43 dB dynamic range and test wavelengths of 1310 nm and 1550 nm. It is designed to locate faults, measure fiber length, quantify loss and detect reflective events, providing precise characterization of optical links for installation, maintenance and troubleshooting of long-haul and access fiber networks.
Advantages
The device provides a high dynamic range of 43 dB for improved event detection and dead zone performance. Dual-wavelength testing at 1310/1550 nm allows measurement across standard single-mode windows. Compact and purpose-built for field use, it supports accurate length and loss measurements and helps identify reflective and non-reflective faults in fiber links.
Suitable for
Installation and acceptance testing of single-mode fiber links
Maintenance and troubleshooting of long-haul and access networks
Verifying splice quality and connector reflections
Measuring fiber length and segment loss
Key specifications
Brand: MikroTik
Model / MPN: QX43-S1
Type: OTDR fiber tester (single-mode)
Dynamic range: 43 dB
Wavelengths: 1310 nm, 1550 nm
How to use
Connect the OTDR to the single-mode fiber under test using the appropriate connector adapter. Select the test wavelength (1310 nm or 1550 nm) and configure the test parameters if needed. Start the trace to measure fiber length, identify events and record losses. Analyze the trace output to locate faults, reflective events and quantify attenuation; repeat tests at both wavelengths for complete characterization.
Usage recommendations
Use the QX43-S1 with clean connectors and proper adapters; perform tests at both 1310 nm and 1550 nm for comprehensive assessment. When testing in the field, protect the device and fiber ends from contamination and mechanical stress to ensure accurate measurements.
