A2300-Type Laser 2000
Description
The Laser 2000, A2300-Type Analog DFB Laser
Module contains a high-performance, Indium Gallium
Arsenide Phosphide, multiquantum-well, distributed-
feedback laser chip designed f or 1310 nm, single-mode
fiber-optic applications. The module is an industry-
standard, 14-pin butterfly-type, hermetic, metal/ceramic
package and houses the laser chip as well as an
integral thermoelectric cooling/heating device, a
thermistor, an integ r al optical isolator, and a laser back-
facet optical monitor. The module is equipped with a
900
µ
m
Hytrel
* jacketed, 8.8
µ
m core, single-mode
fiber; se veral standard fiber-optic connector options are
also available.
The integral thermoelectric cooler (TEC) provides
stable thermal characteristics for the laser chip, as well
as the optical isolator and back-facet monitor
photodiode. The TEC allows for heating and cooling of
these internal optical components and can maintain
their temperature at a constant 25
°
C over the entire
ambient operating temperature range of –20
°
C to
+65
°
C. The thermistor monitors the internal module
temperature and provides f eedback control f or the TEC .
This gives the A2300-type laser 2000 superior, stable
optical characteristics.
When used in a fiber-optic system, reflected light
entering the laser module is attenuated a minimum of
40 dB by the optical isolator. The internal PIN
photodiode monitors the optical power emitted from the
rear facet of the laser diode, and when used in
conjunction with e xterior module circuitry, it can monitor
and control the optical output power launched into the
fiber.
Lucent Technologies offers two different pinout types
and RF drive impedance. The first is the
Optoelectronics unit standard analog isolated laser
module (ILM) pinout, which has an input impedance of
75
Ω
. The 75
Ω
input impedance eliminates the need
for external matching circuits and is achieved using an
RF transformer internal to the package. This allows the
RF drive level into the laser to be typically 4 dB less
than if resistive matching were used. The second
pinout type has a resistive input impedance of 25
Ω
and matches the pinout of the optoelectronic industry’s
standard 2.5 Gbits/s package.
Lucent Technologies analog laser modules feature the
ability to have enhanced performance and value
through the addition of the Optoelectronics unit’s
exclusive predistortion board. The separate
predistortion board provides both CSO and CTB
correction enhancements to the laser module
performance, for 110 NTSC as well as 42 CENELEC
channels. While maintaining extremely low electrical
power dissipation and low insertion loss, the
predistortion board allows 1000 MHz of RF bandwidth.
Every A2300-type laser 2000 module is tested to meet
the customer’ s analog perf ormance specifications, ov er
the specified fiber link budget loss and test channel
plan. This measurement method ensures proper
system performance of the product. Lucent
Technologies Optoelectronics unit components and
products are qualified to the rigorous requirements of

Handling Precautions
Mounting Instructions for Laser Module
The minimum fiber bend radius is 1.25 in. To avoid
degradation in performance, mount the module on the
board as follows:
1. Place the bottom flange of the module on a flat heat
sink at least 0.5 in. x 1.180 in. (12.7 mm x 30 mm) in
size. The surface finish of the heat sink should be
better than 32
µ
in. (0.8
µ
m), and the surf ace flatness
must be better than 0.001 in. (25.4
µ
m). The use of
thermal conductive grease is optional; however,
thermal performance can be improved b y up to 5% if
conductive grease is applied between the bottom
flange and the heat sink.
2. Mount four #2-56 screws with Fillister heads
(M2-3 mm) (see Figure 4) at the four screw-hole
locations (see Outline Diagram, page 7). The Fillister
head diameter must not e xceed 0.140 in. (3.55 mm).
Do not apply more than 1 in.-lb. of torque to the
screws.
Note: Dimensions are in inches and (millimeters).

Power Sequencing
Adopt the f ollowing sequence f or turn-on as a matter of
good practice to avoid the possibility of damage to the
laser module from power supply switching transients.
1. All ground connections.
2. Most negative supply.
3. Most positive supply.
4. All remaining connections.
Reverse the above order for the proper turn-off
sequence.
Electrostatic Discharge
CAUTION:This device is susceptible to damage as
a result of electrostatic discharge. Take
proper precautions during both
handling and testing. Follow guidelines
such as JEDEC Publication No. 108-A
(Dec. 1988).
Lucent employs a human-body model (HBM) for ESD-
susceptibility testing and protection-design evaluation.
ESD voltage thresholds are dependent on the critical
parameters used to define the model. A standard HBM
(resistance = 1.5 k
Ω
, capacitance = 100 pF) is widely
used and, therefore, can be used for comparison
purposes. The HBM ESD threshold presented here
was obtained using these circuit parameters:
