OWLTrek Live Mode
OWLTrek Mini OTDR Series
Live Mode. Live mode is another advanced feature normally found in high-end OTDRs.  Live mode
continuously shoots OTDR traces every few seconds, allowing users to monitor changes in the optical fiber
in real-time.

In addition, when the OWLTrek is attached to a PC, OWLView software includes a Live Viewer mode that
takes the OTDR trace and expands it onto the PC display for easier viewing.

"A knowledgeable fiber optics technician will never use an OTDR without a launch and/or a receive cable!"

Pulse Suppressors, commonly called Launch Cables, are used to occupy OTDR "Dead Zones" which enable accurate loss
measurements on near-end and far-end connections of the fiber under test.  They basically allow the high power launch pulse a "settling
down" time prior to entering the fiber under test. Besides - you would not want to plug a bad connector into the top of your expensive
OTDR would you?  Some OTDR's contain an internal launch cable.  What would happen if you plugged a bad connector into the top of
your OTDR then.  Results - SAME PROBLEM!

This compact suppressor/launch box/launch cable comes with your choice of connectors.  Pigtails will exit the unit for easy connection
to both OTDR and fiber under test.  When running an OTDR trace on multimode fiber the launch/receive cable should be at least 250
meters long.  When running a trace on singlemode fiber the launch cable should be at about 1k in length."

There is a 7-10 day lead time on this item.  Be sure to specify what connectors you require on each end.  Standard connectors are, ST,
FC, LC, and SC.  Give me a call at: 512-785-9024 or email me at: bob@fiberopticstools.com and let me help you.

from the desk of Peter Morcombe
Pioneer of Fiber Optics and Master FOA Instructor
When it comes to buying fiber optic test equipment for use in local
networks and LANs I prefer simple to complex.  Paying tens of
thousands of dollars for “Mighty Wurlitzers” can be problematic if the
equipment has to be returned for factory servicing.

Simple fiber optic test equipment is now so inexpensive one can afford
to buy redundant units to ensure that testing capability is maintained at
all times.    
Thus I am inclined to recommend simple test equipment such as OWL (Optical
WavelengthLaboratories) rather than complex solutions offered by Anritsu or Fluke.  It is
simply a matter of adequate performance at an affordable price.  Read complete article
