Description
The
E2500-Type
EM-I
LM
is
a
1
.5
pm
laser
with
an
integrated
electroabsorptive
modulator
packaged
in
an
industry-standard,
14-pin
butterfly
package
.
The
device
has
been
designed
to
be
used
in
2
.5
Gbits/s
extended-reach
applications
where
the
distances
between
regenerators
is in
the
range
of
150
km-
1000
km
.
To
boost
the
transmitter
power
high
enough
to
reach
the
receiver,
the device
typically
is
coupled
with
an
erbium-doped
fiber
amplifier
(EDFA)
such as
Agere
Systems
Inc
.'s
1724
EDFA
.
The
standard
product
is
specified
for
use up
to
360
km
(E2505
Series)
and600
km
(E2502
Series)
.
The
E2500
EM-ILM
can
replace
external
modulators
in
many
applications
.
The
nominal
input
impedance
for
the
modulator
is
50
52
.
By
integrating
the
modulator
with
the
laser
chip,
the
device
offers
a
compact,
cost-effective
solution
for
extended-reach
transmission
applications
.
It
can
also
be
specified
for
WDM
applications
where
wavelength
selection
is
required
.
Agere
is
providing
devices
compatible
with
the
ITU-T wavelength
standards
.

The
package
also
contains
a
thermoelectric
cooler,
thermistor,
back-facet
monitor,
and
an
optical isolator
.
This
device
exhibits
excellent
wavelength
stability,
supporting
operation
at
100
Gbits/s
channel
spacing,
assuming
an
end-of-life
condition
of <
±100
pm
over
20
years
for
wavelength
aging,
with
very
low
FIT
rates
.
Wavelength
stabilization
schemes
are not
required
in
DWDM
systems
of
this
type,
using
Agere's
E2500-
Type
EM-ILM
.
The E2500-Type
EM-ILM
is
qualified
for
DWDM
appli-
cations
to
Bellcore
