Applications
- Testing and troubleshooting of LAN, telco, CATV and FTTx networks
Corning Cable Systems OptiVisor 400 Optical Time Domain Reflectometer (OTDR)
provides testing flexibility by offering a rugged platform with
field-interchangeable multimode and single-mode modules. All OTDR modules can be
used as CW light source and are available with an optional visual fault locator
(VFL) installed. An optional power meter is available on the OptiVisor 400 OTDR
mainframe. The standard unit provides internal memory for storage of up to 700
traces using Microsoft Windows CE technology, eliminating the need for a hard
drive. If extra storage capacity is needed, there is a 1.44 MB floppy drive on
the mainframe along with a PCMCIA port.
The OptiVisor 400 OTDR product line offers a wide variety of multimode and
single-mode modules including a tri-wavelength single-mode module perfect for
FTTx testing. Modules can be easily switched out in the field, without the use
of tools, in just a matter of seconds.
The OTDR features a 7.7-inch high-quality color LCD touch screen that is
resistant to most common chemicals used in the field. The screen is large enough
to view both the trace and the event table, thereby eliminating the need to
toggle back and forth between the two.
With three testing modes, the OptiVisor 400 OTDR offers something for every
installer. Auto Mode allows the user to select the parameters automatically,
making it perfect for basic OTDR applications or the occasional user. Advanced
Mode offers more setup and measurement capabilities for the experienced OTDR
user. Template Trace Mode allows the user to create a template for comparison
with other traces, ideal for quick testing of multiple fibers.
