Description
The
1241/1243/1245-type
Laser
Transmitters are
designed
for
use
in
transmission
systems
and
high-
speed
data
communication
applications
.
Used
in
intraoffice
and
intermediate-reach
applications,
the
transmitters
are
configured
to
operate
at
SON
ET
rates
up
to
OC-12,
as
well
as
at
ITU-T
synchronous
digital
hierarchy
(SDH)
rates
up
to
STM-4
.
Specific
versions
are also
capable
of
operating
up
to
1062
.5
Mbits/s
.
The
transmitter
meets
all
present
Bellcore
GR-253-
CORE
requirements,
ANSI
T1
.117-1991
SONET
sin-
gle-mode,
and
the
ITU-T
G
.957
and
G
.958
recommen-
dations
.
(See
Table
5
to
select
transmitters
for
the
various
SONET/SDH
segments
.)
The
transmitter
requires
a
single
power
supply
(+5
V
or
-5
V)
and
operates over data
rates of
1
Mbits/s
to
622
Mbits/s
(NRZ)
.
Automatic
power
control
circuitry
provides
constant
optical
output
power
over the operat-
ing
case
temperature
range
.
The
automatic
power
con-
trol
circuitry
also
compensates
for
laser
aging
.
The
optical
wavelength
tolerance
at
25
°C
is
1310
nm
.
The
temperature
coefficient
of
wavelength
for
1
.3
pm
Fabry-
Perot
transmitters
(1241
Type)
is
approximately
0
.4
nm/°C
.
The

of
wavelength
for
1
.3
pm
and
1
.55
pm
distributed-feedback
(DFB)
transmitters
(1243/1245-Type)
is
approximately
0
.1
nm/°C
.
Transmitters
are
available
for
operation
over
several
dif-
ferent
temperature ranges
from
-40
°
C
to
+85
°
C
.
Man-
ufactured
in
a
20-pin
DIP,
the
transmitter
consists
of
a
hermetic,
InGaAs
laser
and
a
single
CMOS
driver
IC
.
The
low-power
consumption
circuit
provides
modula-
tion,
automatic
optical
output
power
control,
and
data
reference
.
The module
can be
driven
by
either
ac-
or
dc-coupled
data
in
single-ended
or
differential
configu-
ration
.
(See
Recommended
User
Interfaces
section
for
typical
connection
schemes
.)
The
laser
bias
and
back-
facet
monitor
currents
are
electrically
accessible
for
transmitter
performance
monitoring
.
The
transmitter
optical
output
may
be
disabled by
a
logic-level
input
.

Description

Operation
Figure

shows
a
simplified
schematic
of
the
transmit-
ter
;
pin
information
is
listed
in
Table
1
.
The
laser
within
the
transmitter
is
driven
by
a
single
CMOS
integrated
circuit,
which
provides
the
input
data
signal
reference
level
with
automatic,
temperature-compensated
laser
bias,
and
modulation-current
control
.
A
back-facet
pho-
todetector
diode
within
the
laser
module
provides
an
indication
of
the
laser's
average
optical
output
power
.
The
back-facet
diode
current
is
accessible as
a
voltage
proportional
to
photocurrent
through
pins
17 and
19
on
the
transmitter
.
The
back-facet
diode
also
forms
part
of
the
feedback
control
circuit,
which
helps
maintain con-
stant
output
power
.
The
laser
bias current
is
accessible
as a
dc-voltage by
measuring
the
voltage
developed
across
pins
2
and
4
of
the
transmitter
.
Dividing
this
voltage
by
10
52
will
yield
the
value
of
the
laser
bias
current
.
This
value
will
change
up
or
down
in
response
to
operating
tempera-
ture,
power
supply
voltage,
data
pattern,
and
laser
aging
characteristics
.

Schematic
Input
Data
Input
Data
Data
enters
the
transmitter
through
a
comparator
.
These
inputs
have
internal
pull-down
resistors
to
a
volt-
age
reference
that
is
1
.3
V
below
Vcc
.
This
configura-
tion
allows
the
transmitter
to
be
driven
from
either
a
single-ended
or
a
differential
input
signal
.
Since
the
input
is
a
comparator
instead
of
a
gate,
the
absolute
input
signal
levels
are
not
important
when
the
inputs
are driven
differentially
.
When
driven
single-ended,
however,
the
input
signal
voltage
should
be
centered
around
Vcc-
1
.3
V
to
eliminate
pulse-width
distortion
.
With
a
single-ended
input,
either
input
can
be
used and
the
unused
input
can be
left
as
an
open
circuit
due
to
the
internal
reference
shown
in
Figure
1
.
The
optical
output
signal
will
be
in
the
same
sense
as
the
input
data-an
input
logic
high
turns
the
laser
diode
on and
an
input
logic
low
turns
the
laser
diode
off
.
However,
if
the
negative
input
is
used
with
a
single-ended data
input
signal,
the
optical
signal
will
be
the
complement
of
the
data
input
signal
.
The
differental
inputs
of
the
1241
Gbit
versions
are
ter-
minat
ed
internally
with
100
52
between
the
DATA
and
DATA
inputs
.
Minimum
Data Rate
Because
the
modulation
and
bias
control
circuitry
are
influenced
by the
input
data
pattern,
the
standard
transmitter
cannot
be
used
in
burst-mode
type
applica-
tions
.
For
burst-mode
applications,
please

rate
(pseudorandom

50%

cycle)
for

Functional
Overview
(continued)
Since
most
applications
operate
at
very
high
data
rates,
high-frequency
design
techniques
need
to
be
used
to
ensure
optimum
performance
from
the
trans-
mitter
and
interfacing
circuitry
.
Input
signal
paths
should
be
kept
as
short
and
as
straight
as
possible
;
dif-
ferential
signal
lines
should
be
equal
in
length,
and
controlled-impedance
stripline
or
microstrip
construc-
tion
should
always
be used
when
laying
out the
printed-
wiring
board
traces
for
the
data
lines
.
The
Recom-
mended
User
Interfaces
section
of
this
data
sheet
shows
several
methods
of
interfacing
to
the
transmitter
.
Power
Supplies
The
transmitter
is
configured
for
operation
from
either
a
single
+5
V
power
supply
or
a
single
-5
V
power
sup-
ply
.
For
positive
power
supply
operation,
connect
Vcc
to
the
+5
V
power
supply
and
connect
VEE
to
ground
or
circuit
common
.
For
operation
from
a -5
V
power
sup-
ply,
connect
Vcc
to
ground and connect
VEE
to
the
-5
V
power
supply
.
Whichever
option
is
chosen,
the
Vcc
or
VEE
connection
to
the
transmitter
should
be
well
filtered
to
prevent
power
supply
noise
from
interfering
with
transmitter
operation
.
Transmitter Specifications
Optical
Output
Power
During manufacture, the
optical
output
power
of
every
transmitter
is
tuned
to
the
typical
value
specified
in
the
data
sheet
for
that
particular
transmitter
code
.
The
tun-
ing
is
performed
at
room
ambient
and
a
power
supply
voltage
of 5
V
.
The
minimum
and
maximum
values
listed
in
the
data
sheet
for
each
code
group
reflect
the
worst-case
limits
that
the
transmitter
is
expected
to
operate
within
over
its
lifetime
and
over
the
allowed
power
supply
and
the
operating
temperature range
.
Every
transmitter
shipped
receives
a
final test,
which
includes
a
SON
ET
eye-mask
test at either
the
OC-3
(STM-1)
data
rate of
155
.52 Mbits/s,
the
OC-12
(STM4)
data
rate
of
622
.08
Mbits/s,
or
the
fibre
channel
FC-0
data
rate
of
1062
.5
Mbits/s
.
The

is
meant
to

Handling
Precautions
CAUTION
:
This
device
is
susceptible
to
damage
as
a
result
of
electrostatic
discharge(ESD)
.
Take
proper
precautions
during
both
handling
and
testing
.
Follow
guidelines
such
as
JEDEC
Publication
No
.
108-A
(Dec
.
1988)
.
Although
protection
circuitry
is
designed
into
the
device,
take
proper
precautions
to
avoid
exposure
to
ESD
.
Agere
employs
a
human-body
model
(HBM)
for
ESD-susceptibility
testing
and
protection-design
evalu-
ation
.
ESD
voltage
thresholds
are
dependent
on
the
critical
parameters used
to
define
the
model
.
A
stan-
dard
H
BM
(resistance
=
1
.5
k52,
capacitance
= 100 p
F)
is
widely
used
and,
therefore,
can be used
for
compari-
son purposes
.
The
HBM
ESD
withstand voltage
estab-
lished
for
the
1241-/1243
TypgTransmitter
is
±1000V
.
Transmitter
Processing
The
transmitter
can
withstand
normal
wave-soldering
processes
.
The
complete
transmitter
module
is
not
her-
metically
sealed
;
therefore,
it
should
not
be
immersed
in
or
sprayed
with
any
cleaning
solution
or
solvents
.
The
process
cap
and
fiber
pigtail
jacket
deformation
temperature
is
85
°C
.
Transmitter
pins
can
be
wave-
soldered
at
maximum
temperature
of
250
°C
for
10
seconds
.
Installation
Considerations
Although
the
transmitter
features
a
robust
design,
care
should
be
used
during
handling
.
The
optical
connector
should
be
kept
free
from
dust,
and
the
process
cap
should
be
kept
in
place
as
a
dust
cover
when
the
device
is
not
connected
to
a
cable
.
If
contamination
is
present
on
the
optical
connector,
canned
air
with
an
extension
tube
can be used
to
remove
any
debris
.
Other
cleaning
procedures
are
