Fig. 5-1 Main Operation Interface Diagram of VFL VFL provides two kinds of using status--“bright permanently”, “twinkling”. Clicking the button “bright permanently”, the VFL will enter turn-on status of permanent lightening; clicking the button “twinkling”, the VFL will enter turn-on status of 2Hz twinkling; clicking the button “OFF”, the VFL will turn off immediately.
6 Introduction to OTDR 6.1 Measuring Purpose of OTDR OTDR displays the power of the returned signal related to distance. The information can be used to confirm the transmission quality of a fiber optic link. 6.1.
Distance calculation formula of OTDR: Distance = (c/n) × (t/2) Among which: c= speed of light in vacuum (2.998 x 108 m/s) t = Time delay between transmitted pulse and received pulse n = refractivity of optical fiber during testing process (nominated by manufacturer) When displaying the whole trace, each point on the trace graph represents the average value of several sampling points. The value of each sampling point can be found by reducing or magnifying the trace. Fig. 6-1. OTDR Principle Diagram 6.
Fig.6-2 Reflection Event 6.3.4 Non-reflection Event Non-reflection event brings loss on the whole transmission link of optical fiber, but no light reflection. On the curve, non-reflection event is shown as drop of optical power, as shown in Fig.6-3. Fig.6-3 Non-reflection Event 6.3.5 Event Inspection OTDR sends optical pulse into the optical fiber that waited for inspection, then, begins to accept the returned optical signal immediately, and calculate the distance of “event” in the optical fiber.
