The
TOP
Optica!
LED
Source
The
Tektronix
TOPI
30
Dual-Wavelength
(850/1300nm)
Optical
LED
Source
is
a
small,
rugged
handheld
instrument
for
use
in
installing
and
testing
attenuation
of
both
singlemode
and
multimode
fiber
optic
links,
including
telephony,
datacom,
CATV,
FDD
I
and
LAN
applications.
The
instrument
provides
two
calibrated
outputs
at
850nm
and
1300nm
to
speed
up
transmission
loss
measurements.
Providing
both
CW
and
MODulated
outputs,
the
user
can
internally
set
the
modulation
frequency
to
match
the
frequency
signatures
(270/1000/2000Hz)
required
by
fiber
identifiers
and
signal
tracers.
The
palm-sized
TOPI30
provides
the
flexibility
in
a
single
unit
to
interface
to
all
industry
standard
fiber-optic
connectors
with
high
throughput,
repeatability
and
stability.
This
optical
interface
of
this
instrument
features
the
precision
snap-on
connector
(SOC)
interface.
A
wide
range
of
push-pull
SOC
adapters
are
available
covering
all
popular
industry-standard
fiber-optic
connectors
(including
FC,
ST,
SC,
SMA,
E2000,
DIAMOND,
etc.).
The
TOP
series
LED
source
is
powered
by
two
common
AA
alkaline
batteries
which
provide
over
20
hours
of
portable
life.

high-performance
fiber
optic
test
set
in
its
class.
Overview
1.1.2
The
TOP
Optical
Laser
Sources
The
Tektronix
TOP
Series
comprise
a
range
of
palm-sized,
single
and
dual
wavelength
laser
sources
supporting
the
1310nm
and
1550nm
windows.
This
series
was
developed
in
response
to
requests
from
the
fiber
optic
industry
for
small,
rugged
light
sources
for
use
in
installing,
maintaining
and
researching
singlemode
SONET/SDH,
CATV,
ATM
and
other
types
of
fiber
optic
links.
The
TOPI
40
(1310nm)
and
TOPI
50
(1550nm)
were
developed
for
applications
requiring
only
a
single
wavelength
source.
Where
loss
measurements
at
both
windows
are
required,
the
TOPI60
also
offers
the
added
convenience
of
a
single
output
port.
The
optical
interface
of
the
TOP
series
optical
laser
sources
is
the
high
performance,
universal
connector
interface
(UCI).
The
UCI
interface
is
ideally
suited
to
the
unique
requirements
of
optical
instrumentation
whether
in
the
most-demanding
outside
plant
(OSP)
or
lab
environment.
First,
being
truly
universal,
the
UCI
interface
is
complemented
by
a
full
range
of
UCI
screw-on/screw-off
connector
adapters
supporting
a
broad
range
of
industry-standard
PC
connector
types
(FC,
SC,
ST,
D4,
DIN,
E2000
and
more).
Second,
where
cleaning
connectors
is
an
especially
important
and
routine
step
in
the
optical
fiber
world
,
the
UCI
interface
offers
direct
access
for
routine
cleaning.
Third,
the
durable
tungsten
carbide
ferrule
outperforms
and
outlasts
traditional
ceramic
ferrule
connectors.
In
addition
to
the
overall
advantages
of
the
UCI
interface,
the
output
signal
performance
is
characterized
by
two
useful
features.
One,
the
absolute
output
power
is
calibrated
which
can
speed
up
transmission-loss
measurements.
The
user
can
always
be
assured
that
the
output
level
will
be
consistent
every
time
the
unit
is
powered
on.
Furthermore,
this
reproducibility
is
matched
by
the
multiwavelength
reference
storage
of
the
TOP200
optical
power
meter
(see
section
3.4
-
TOP200
and
section
4.6
-
Dual
Wavelength
Testing).
Two,
using
the
user-selectable
CW
or
MODuiated
function,
the
user
can
also
internally
set
the
MOD
frequency
to
match
the
frequency
signatures
(270/1000/2000Hz)
required
by
fiber
identifiers
and
other
types
of
optical
signal
tracers.
Together
with
the
Tektronix
TOP200
optical
power
meter,
the
fiber
optic
technician
possesses
the
smallest
and
high
performance
test
set
in
its
class.

1.1.3
The
TOP200
Optical
Power
Meter
The
paim-sized
Tektronix
TOP
200
optical
power
meter
covers
an
extensive
range
of
optical
fiber
applications.
It
is
engineered
for
field
and
lab
personnel
requiring
a
high-
performance,
cost-effective,
compact
and
rugged
optical
power
meter.
This
power
meter
family
incorporates
the
precision
and
repeatability
of
the
snap-on
connector
interface
(SOC)
which
interfaces
to
all
industry
standard
fiber
optic
connectors
via
a
complete
line
of
simple,
push-on/pull-off
SOC
adapters.
The
novel
design
of
these
power
meters
combines
a
state-of-the-art
signal
processor
and
microcomputer
electronics
to
provide
superb
performance
as
well
as
simple
and
elegant
operation.
Only
three
controls
are
used:
ON/OFF,
dBm/dB
and
X
(wavelength).
The
TOP200
optical
power
meter
incorporates
a
state-of-the
art
InGaAs
photodiode
for
optimum
IR
wavelength
performance.
InGaAs
detectors
provide
wide
dynamic
range
and
improved
temperature
stability
as
compared
to
the
Ge
detectors.
The
TOP200
also
features
non-voiatiie
memory
together
with
an
internal
CAL
function
allowing
the
user
the
option
to
recalibrate
the
instrument
in
his/her
own
lab.
The
power
meters
are
powered
by
two
common
AA
batteries
which
provide
over
100
hours
of
operating
life.
The
custom
LCD
provides
simultaneous
display
of
both
wavelength
and
dBm/dB
units
as
well
as
battery
status.
Together
with
the
Tektronix
TOP
series
sources,
the
fiber
optic
technician
possesses
the
smallest
and
highest-performance
fiber
optic
test
set
in
its
class.

The
TOP
Fiber-Optic
Visual
Fault
Finder
The
Tektronix
TOP300
answers
the
request
from
the
industry
for
a
small,
rugged
and
truly
versatile
visual
fault
finder
(VFF)
for
use
in
the
installation,
maintenance
and
troubleshooting
of
fiber
optic
systems.
This
palm-sized
visual
fault
finder
features
both
CW
and
MOD
(blinking)
output
modes.
The
blinking
mode
is
used
for
finding
faults
and
breaks
in
any
fiber.
The
blinking
light
enhances
viewing
contrast,
light
loss
can
easily
be
detected
by
the
human
eye.
Steady
CW
light
output
may
be
used
for
measuring
fiber
loss
in
the
visible
630nm
wavelength
region.
The
VFF
may
also
serve
as
a
substitute
for
HeNe
gas
laser
applications.
The
TOP300
employs
a
hermetically
sealed
laser
diode
coupled
to
the
fiber
interface.
Two
AA
alkaline
batteries
power
the
unit
for
a
minimum
of
20
hours.
Like
the
TOPI40/150/160
optical
laser
sources,
the
TOP300
also
features
the
precision
universal
connector
interface
(UCI)
which
interfaces
to
all
standard
fiber
optic
connectors
via
a
complete
line
of
simple,
screw-on/screw-off
UCI
adapters.
