Description
The
D2300-Type
Digital
Isolated
DFB
Laser
Module
contains
an
internally
cooled,
InGaAsP,
distributed-
feedback (DFB)
laser
designed
for
1
.3
pm
applications
.
The
laser
is
designed
to
be
used
in
OC-12/STM-4
(622
Mbits/s)
and
OC-48/STM-16
(2 .488
Gbits/s)
for
long-reach
and
extended-reach
applications
.
The
device
is
available
with
an
average
output
power
of
0
dBm
(3
dBm
peak),
which
meets
the
SONET/SDH
standard
.
Controlled
Feedback
The module
contains
an
internal optical isolator
that
suppresses
optical
feedback
in
laser-based,
fiber-optic
systems
.
Light
reflected
back
to
the
laser
is
attenuated
a
minimum
of
30
dB
.
Controlled
Temperature
An
integral
thermoelectric cooler
(TEC)
provides
stable
thermal
characteristics
.
The
TEC
allows
for
heating
and
cooling
of
the
laser
chip
to
maintain
a
temperature
of
25°C
for
case
temperatures
from
-40
°C
to
+75
°C
.
The
laser
temperature
is
monitored
by
the
internal ther-
mistor,
which
can
be
used
with
external
circuitry
to
con-
trol
the
laser
chip
temperature
.
Controlled
Power
An
internal,
InGaAs,
PIN
photodiode
functions
as
the
back-facet
monitor
.
The
photodiode
monitors
emission
from
the
rear
facet
of
the
laser
and,
when
used
in
con-
junction with control
circuitry,
can
control optical
power
launched
into
the
fiber
.
Normally,
this
configuration
is
used
in
a feedback
arrangement
to
maintain
the
aver-
age
laser
output
power
.
Standard
Package
The
laser
module
is
fabricated
in
a
14-pin,
hermetic,
metal/ceramic
butterfly
package
.
The
package
also
incorporates
a
bias
tee
that
separates
the
dc-bias
path
from
the
RF
input
.
The
RF
input
has
a
nominal
25
52,
impedance
.
The
laser
module
is
equipped
with
a
sin-
gle-mode
fiber
.
The
pigtail
has
an 8
pm
core
and
125
gm
cladding
with
a
900
gm
tight
buffer
coating
.
Optoelectronic
components
produced
by
Agere
Sys-
tems
Inc
.
are
qualified
to
rigorous
internal
standards
that
are
consistent
with
Telcordia
Technologies
TR-
NWT-000468
.
All
design
and
manufacturing
operations
are
ISO°9001
certified
.
The
module
is
fully
qualified
for
central
office
applications
.

ule
on
the
board
as
follows
:
1
.Place
the
bottom
flange
of
the
module
on a
flat
heat

.
The
surface
finish
of
the

should
be
bet-
ter
than
32
pin
.
(0
.8
pm),
and
the
surface
flatness
must
be
better
than
0
.001
in
.
(25
.4

.
Using
thermal
con-
ductive
grease
is
optional
;
however,
thermal
perfor-
mance
can be
improved
by up
to
5%
if
conductive
grease
is
applied
between
the
bottom
flange
and
the
heat
sink
.
