    5.2.2 Single event analysis - Insertion loss and reflectance Due to the very high resolution and the short dead-zones the LOR-200/220 is capable of making in- sertion loss measurement on very short fiber samples. In this example session we show that even the insertion loss and the reflectance of the output connector of the instrument can be measured.

    5.2.4 Length measurements Due to the very high resolution, the LOR-200/220 enables precise length measurements on optical fibers. A semi-automatic software tool is supplied which simplifies this task. The positions of two user selected peaks are precisely localized by an automatic quadratic peak fitting algorithm and their distance is calculated automatically.

  • Page 28: Testing A Passive Optical Network (Pon)

    5.2.5 Testing a passive optical network (PON) There are several applications where this type of high-resolution and high-sensitivity photon- counting OTDR can outperform conventional OTDRs. All conditions, where a high spatial resolution measurement on low backscattered signals is required are typical fields of application. One exam- ple is a passive optical network (PON).
  • Page 29 Figure 24: PON OTDR trace 300 ns pulsewidth Fiber loss measurements and an insertion loss test of the first coupler have been done as described in sections 5.2.1 and 5.2.2. The resolution of this first measurement is insufficient to resolve the location of the optical network terminals simulated by the open fiber ends.

    5.2.6 Comparing traces This example session demonstrates the use of the LOR-200/220 for trace comparison. The meas- ured trace is compared with one or more previously stored traces to monitor changes in fiber loss- es or peak locations. The first example monitors the length of an optical fiber of 7.8 km length as the ambient tempera- ture varies.
