Page 6: Before You Begin
SECTION 1: INTRODUCTION BEFORE YOU BEGIN All personnel testing optical fibers should be adequately trained in the field of fiber optics before using any fiber optic test equipment. If the user is not completely familiar with testing fiber optics, they should seek competent training. Such training can be acquired from a variety of sources, such as local hands-on training classes or online courses. -
Page 7: Description
SECTION 1: INTRODUCTION DESCRIPTION Upholding OWL’s commitment to high-quality, yet affordable, fiber optic test equipment, the OWLTrek II OTDR enables fiber optic professionals to quickly and easily troubleshoot and locate optical faults in singlemode fibers. The OWLTrek II is truly a hand-held unit, being one of the smallest OTDRs on the market today – easily able to fit into a shirt pocket –... -
Page 8: Precautions
SECTION 1: INTRODUCTION PRECAUTIONS Eye Safety NEVER look into the connector port of any fiber optic test or transmission equipment, patch cable, fiber link, or other installed fiber. Always assume that active laser equipment is attached to optical fibers, and is powered on. Do not run a test on the OTDR unless it is connected to the fiber under test, or the dustcap is firmly in place. -

Page 17: Fiber Length Measurement/Link Loss
SECTION 3: TRACE ANALYSIS FIBER LENGTH MEASUREMENT/LINK LOSS By placing the cursors at the beginning and ending points of the fiber trace, the Fiber # AUTO distance between the cursors will show a close approximation of the total length of the optical fiber link, as well as a close approximation of the total fiber link loss. -
Page 18: Reflectance Measurement
SECTION 3: TRACE ANALYSIS REFLECTANCE MEASUREMENT The reflectance of a specific event can be determined by placing the cursors on Fiber # AUTO either side of an event. The OTDR will show the reflectance in dB of the highest reflective event between the cursors. CURSOR PLACEMENT Proper cursor placement is important when determining the reflectance of a reflective event. -
Page 19: Detector Saturation
SECTION 3: TRACE ANALYSIS SATURATION INVERSION Some highly reflective events are so reflective that they “over-drive” the OTDR Fiber # AUTO circuitry, and cause the OTDR graph to appear as if the trace completely drops out. This issue is called “saturation inversion”, and only appears when overly- reflective light causes the internal OTDR circuitry to become saturated. -

Battery Replacement. The OWLTrek II contains an internal Lithium Polymer battery. If the battery requires service, the device must be sent in to OWL. Unauthorized attempts to service the battery will void the product warranty. Cleaning. For accurate readings, the optical connector port on the OWLTrek II and the connector on the patch cable should be cleaned prior to attaching them to each other.
