Testing a splitter or other passive fiber optic devices like switches is little different from testing a patchcord or cable plant using the two industry standard tests, OFSTP-14 for double-ended loss ...

Testing the attenuation of the 18-splitter - Budowa Silesia Photonics [PDF]
Wavelength-division multiplexers can be tricky to test because they require sources at a precise wavelenth and spectral width, but otherwise the test procedures are similar to other passive
U Band 1625-1675 nm ial causes an increase in attenuation. These ions result from the presence of water that enters the cable material through either a chemical reaction in the manufacturing pro ess
To accurately assess signal loss and verify that splitter installations are performing within expected parameters, you can test power levels using specialised fibre optic test equipment.
When testing optical splitters, several common issues can arise that may affect the accuracy of your results. Understanding these issues and knowing how to troubleshoot them is
Testing spectral attenuation is done per TIA/EIA-455-61 or IEC 61300-3-7 with broadband sources like LEDs and a spectrum analyzer on the receiving end of the fiber.
It outlines the basics of passive optical network infrastructure, describes the most common attenuation mechanisms in optical fibers and the testing methodology for measuring optical splitter performance.
Any attenuation which differs substantially from this amount indicates a problem with the cable, such as a poor connector, physical damage such as a sharp crimp or bend, or moisture in the cable.
Loss testing, as a necessary testing item of optical splitters, can be done by using an optical power meter and light source. This tutorial illustrated the details of using an optical power
Attenuation testing is required in both directions using appropriate wavelengths for splitters and WDM mux/demux. For this testing, a TS, OPM, and reference cables are used, similar to when testing
This testing document lists the equipment and techniques necessary to meet those installation obligations. Any questions or issues regarding this testing standard should be addressed to UTOPIA
