Description

The Direct Modulated Isolated DFB Laser Module
contains an internally cooled, InGaAs, MQW, distrib­uted-feedback (DFB) laser designed for 1.5 µm appli­cations. The f ollowing three d irect-modulation D WDM
product families have been established to meet vari­ous OC-48/STM-16 system applications:

■

D2526-type: designed to be used in OC-48/
STM-16 (2.488 Gbits/s) for extended reach, dense
WDM applications (1800 ps/nm). The wavelength
of the laser can be temperature-tuned for precise
wavelength selection by adjusting the temperature
of the internal thermoelectric cooler.

■

D2555-type: high-perf ormance device designe d for
very low dispersion; used in fi ber sp ans exceeding
170 km (3000 ps/nm).

■

D2570-type: high-power, direct-modulated laser
eliminates the need for optic al amplifier s in DWDM
many applications.

Description

(continued)

Controlled Feedback

The module contains an internal optical isolator that
suppresses optical fee dbac k in l aser-based, fi ber-opt ic
systems. Light reflected back to the laser is attenuated
a minimum of 30 dB.

Controlled Temperature

An integral thermoelectric cooler (TEC) provides stab le
thermal characteristics. The TEC allows for heating
and cooling of the laser chip to mai ntain a te mper ature
of 25 °C for case temperatures from –40 °C to +70 °C .
The laser temperature is monitored by the internal
thermistor, which can be used wi th external circuitry to
control the laser chip temperature.

Controlled Power

An internal, InGaAs, PIN photodiode functions as the
back-f a ce t moni tor. The photodiode monitors emission
from the rear facet of the laser and, when used in con­junction with control circuitry, can control optical power
launched into the fiber. Normally, this configuration is
used in a feedback arr angement to maintain consistent
laser output power.

Standard Package

The laser module is fabricated in a 14-pin, hermetic,
metal/ceramic butterfly package that incorporates a
bias tee, which separates the dc-bias path from the RF
input. The RF input has a nominal 25 Ω impedance.

The laser module is equipped with

SMF-28

The fiber has a 900 µm tight buffer jacket. Var ious con­nectors and pigtail lengths are available.

Absolute Maximum Rat ings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso­lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the performance characteristics of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Handling Precautions

Power Sequencing

To avoid the possibility of damage to the laser module
from power supply switching transients, follow this turn­on sequence:

1. All ground connections

2. Most negative supply

3. Most positive supply

4. All remaining connections
Reverse the 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).

Mounting Instructions

The minimum fiber bend radius is 1.23 in (31.25 mm).
To avoid degradation in performance, mount the mod-

ule 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 µin. (0.8 µm), and the surf ace flatness
must be better than 0.001 in. (25.4 µm). Using ther­mal conductive grease is optional ; how ever, thermal
performance can be improved by up to 5% if con­ductive grease is app lied betwe en the bottom flange
and the heat sink.

2. Mount four #2-56 screws with Fillister heads
(M2-3 mm) at the four screw hole locations (see
Outline Diagram). The Fillister head diameter must
not exceed 0.140 in. (3.55 mm). Do not apply more
than 1 in./lb. of torque to the screws.

Agere Systems 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 k¾, 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:
