OWL OWLTrek II LC Multimode OTDR

An Optical Time Domain Reflectometer (OTDR) is a device that tests the integrity of a fiber cable and is used for the building, certifying, maintaining, and troubleshooting fiber optic systems. Hand-held OTDRs build a virtual image of the fiber optic cable to determine the condition and performance capability of the fiber cable. These tools can also test components along the cable path like connection points, bends, or splices to analyze the cable’s capability from start to finish.

Dynamic Range / Distance: OWLTrek II multimode OTDRs are capable of finding breaks in multimode optical fibers up to 12 miles to within +/- 6 feet. Additional splices and other loss producing events will limit end distance estimates. This is true for all OTDRs. However, passive multimode links are rarely longer than 1.25 miles long! At that short distance, OWLTrek II has break-finding capability of about +/- 1 meter! In fact, increased dynamic range is actually a disadvantage in almost all cases because of the increased OTDR cost (usually thousands of dollars more).

Optional Integrated Optical Power Meter (OPM): models are available that include an integrated optical power/loss meter.  Below are the specifications of the OPM port. With an unbeatable combination of a small pocket-sized form factor, a high-resolution color LCD display, and some of the lowest pricing in the industry, the OWLTrek II OTDR from OWL is the WISE choice for cost-conscious buyers who only need to perform basic troubleshooting or restoration tasks on multimode optical fiber networks. All this from an OTDR that really is pocket-sized and fair priced, yet having comparable features and specifications to other OTDRs in its class.

Affordability. In a time when it is becoming increasingly difficult to justify equipping an entire technical staff with high-end equipment, companies are even more cost-conscious than before. These companies outfit a majority of their installation/repair personnel with OWLTrek II OTDRs, and set aside a few high-end “expert” devices for high-priority jobs.

Automatic event location is an advanced feature normally found only in expensive, high-end OTDRs. The OWLTrek II OTDR now brings this feature to the entry-level OTDR market.

The OWLTrek II OTDR includes an event table showing the location, type, reflectance level, and loss of each event. Users can select an event to view, and automatically zoom in on the event on the OTDR display.


NEW! With the release of firmware version 2.17, users can now view events as a graphical representation of their fiber link!



OWLView software allows the user to download stored traces from the OWLTrek II OTDR to a PC.
