Correctly performing OTDR tests is essential for the performance of the fibre network.
Understand the pros and cons of OTDR testing with these tips and suggestions:
1. Reflections occur at connector pairs, mechanical splices and fibre ends or breaks. Fusion splices and bends do not cause reflections.
2. New APC connectors with reflections of -77 dB or less may not be measurable by OTDRs.
3. Optical return loss (ORL) is the total reflected power, expressed in dB.
4. Bending detection requires testing at 1310 nm and 1550 nm. Bends can exceed 6 dB of loss and may appear as fibre ends. In single-wavelength acquisitions, bends cannot be identified by OTDRs.
5. Inspect before connecting – Always check patch cords and patch ports, including your OTDR. If you have a microscope, it is recommended that you use it.
6. Use a coupler to inspect patch cords and network ports.
