OTDRs

An Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fibre optic cables and systems. It can locate and measure connector and splice losses, measure length and detect network infrastructure issues. The OTDR is also commonly used to create a "picture" of fibre optic cable system when newly installed which can then be compared to later images to characterise modifications / degradation or trouble shoot and locate faults.
