OTDR traces have several common characteristics. Most traces begin with an initial input pulse that is a result of a Fresnel reflection occurring at the connection to the OTDR. Following this pulse, the OTDR trace is a curve sloping downward and interrupted by gradual shifts. The OTDR produces a blind area because the OTDR's detector is temporarily "blinded" by the high intensity Fresnel reflection light (mainly caused by the air gap between the OTDR connections).

OTDR pulse width determines length of fiber that can be measured before OTDR traces become noise. OTDR: General Questions. Q: What do OTDRs test? A: OTDRs test the overall length, loss and optical return loss of fiber optic cables or networks. Additionally What Is OTDR Testing?

OTDR injects a series of optical pulses into the fiber under test. The Optical Time Domain Reflectometer (OTDR) is useful for testing the integrity of fiber optic cables.

And just as with your window, you can have too much Fresnel Reflection to the point you can hardly see anything beyond the window. The OTDR is exactly the same. What Is OTDR?

OTDR (Optical Time Domain Reflectometer) is widely used in all phases of a fiber system's life, from construction to maintenance to fault locating and restoration. However, even a trained and experienced OTDR operator may have difficulty interpreting a fiber trace at times. Another place this problem shows up is in splice closures. An OTDR may show a bad splice, but it can actually be a crack or stress point somewhere else in the splice closure.
