                                    The TEKTRONIX TFP2A FiberMaster Optical Time-Domain
Reflectometer (OTDR) is
an optical-fiber test instrument capable of measuring loss
characteristics and
displaying faults, splices, and other fiber events in
singlemode and multimode optical
FiberMaster applies pulses of light to the fiber under test
via the optical output
connector. As the pulses travel through the fiber, some
light is reflected back to the
instrument. These reflections are processed to display a
visual representation of the
fiber on FiberMaster’s cathode ray tube (CRT), where you can
make distance and
loss measurements on the fiber under test.
The CRT display is a time plot, read from left to right. The
trace starts with the
outgoing pulse, and the time difference is converted to
distance in the measurement
process. When you view a typical fiber display, events that
are further down the fiber
appear to the right (later in time). Loss is measured on the
CRT’s vertical scale.

Modular, Plug-In Laser Sources
The FiberMaster OTDR was designed using a modular approach
that allows you
to choose options that answer your specific test and
measurement applications.
You can upgrade your instrument configuration as your system
change. FiberMaster can accommodate 850-nanometer (nm)
multimode, 1300-
nm multimode, 1310-nm singlemode, and 1550-nm singlemode
laser sources in
one or two plug-in modules. The modules can contain either
two singlemode or
two multimode lasers, or any single laser, allowing the
instrument to be
configured with one to all four wavelengths.
Temperature-controlled laser light sources ensure stable
wavelength and optical
output for highly accurate measurements.
Accurate, High-Speed
Data Acquisition and Measurement
 The internal 32-bit microprocessor performs up to 16
million high-speed
averages per acquisition, maximizing the signal-to-noise
ratio, giving a clear
display of fiber events.
 FiberMaster measures a specific fiber feature, with
convenience. In addition, manual adjustments provide
extended flexibility in
interpreting the fiber data.
 An expand function allows you to magnify any portion or
feature on the displayed
fiber acquisition.
 FiberMaster’s high-density acquisition capability offers
extended expansion
capacity and highly accurate measurements.
 A masking function can be performed automatically, or you
can set manual
masks to reduce dead zones caused by large Fresnel
reflections, improving
measurement resolution.
Automatic and Manual Event Marking
The instrument’s event-marking function automatically
locates and measures
events on the fiber under test that have splice losses above
a user-specified
threshold, or you can also mark events manually.
An event table is compiled displaying the measurements for
each marked event.
You can edit and print out this table, plus enter notes and
mapping information
about each event.

Extended Memory and
Storage Capacity
FiberMaster offers both a current memory, containing the
current data
acquisition, and a reference memory, for previously acquired
fiber waveform
data. A dual-trace mode makes it possible to display the
contents of both current
and reference memory simultaneously, allowing you to compare
a current
optical-fiber acquisition to historical data.
Mass-storage devices (the standard floppy-disk drive and
optional internal RAM)
permit unlimited storage of waveform and settings data on
both removable and
internal media.
Hardcopy Options
You can choose the optional high-speed internal thermal
printer, or use
FiberMaster with either an IEEE 488 general-purpose
interface bus (GPIB)
external plotter or printer, or an RS232 external plotter or
printer. One press of a
button on the instrument’s front panel provides a 15-second
hard copy of the
displayed waveform and instrument settings on the internal
Remote Control Capability
The FiberMaster OTDR can be operated under the remote
control of an
instrument controller or a computer with a GPIB interface,
using an IEEE 488
general-purpose interface bus, or via the RS-232 serial
Additional Features
 An easy-to-use menu system simplifies setting instrument
 You can upload and download waveform and settings data
using the RS232
interface and XModem protocol.
 The 7-inch diagonal, high-resolution color or monochrome
CRT provides a
comprehensive on-screen readout of waveform and measurement
data, and
instrument settings.
