Description

June 2001

Offering multiple channel selections and SONET/SDH compat­ibility, the CW20P-Type CW DBR Laser Module is manufac­tured in a 24-pin metallic DIP with a polarization-maintaining
fiber (PMF) pigtail.

Features

■

Tunable up to twenty ITU-T 50 GHz channels

■

For use with lithium niobate modulators

■

Integrated Etalon stabilizer
—Replaces external wavelength lockers

■

1528.77 nm to 1610.0 nm wavelengths

■

Compact design

■

Remote programmability

■

Asynchronous serial interface for module communi­cation

■

High output power, up to 20 mW

■

Low profile, 24-pin package

The CW20P-type laser modules are designed for use
in transmission systems and high-speed data com­munication applications. The device supports
20 wavelengths. The module uses an RS-232 inter­face to adjust various module functions such as
wavelength. In addition, the interface provides acces­sibility to the alarm and monitor outputs.

The modules meet all present

gies

* GR-253-CORE requirements and the ITU-T

Telcordia Technolo-

G.957 and G.958 recommendations. The modules
are also suited for extended distance data and net­working applications when used in conjunction with a
lithium niobate modulator.

The CW20P uses a 1.5 µm distributed Bragg reflec­tor (DBR) laser with an integrated wavelength stabi­lizer. By integrating the wav elength stabilizer with the
DBR laser chip, the device offers a compact, cost­effective solution for low-dispersion transmission.
Devices are provided at wavelengths that are com­patible with the ITU-T wavelength standards at
200 GHz, 100 GHz, and 50 GHz. The package also
contains a thermoelectric cooler, thermistor, back­facet monitor, and optical isolator. The laser module
requires 5 V, –5.2 V, and 3.3 V.

Module Processing

The module can withstand normal wave soldering pro­cesses. The complete transmitter module is not her­metically sealed; therefore, it should not be immersed
in or sprayed with any cleaning solution or solvents.
The process cap and fiber pigtail jacket can deform at
temperatures greater than 85 °C. The transmitter pins
can be wave-soldered at a maximum temperature of
250 °C for 10 seconds.

Connector Options

The standard fiber-optic pigtail is an 8 µm core PMF
panda-type fiber. (914 µm) diameter, tight-buffered
outer jacket. The standard length is 39 in. ± 4 in.
(1 m ± 10 cm) and is terminated with an

ST

®

optical

connector.

Installation Considerations

Although the module has been designed with rugged­ness in mind, 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, the
use of canned air with an extension tube should
remove any debris. Other cleaning procedures are
identified in the
nical Note (TN95-010LWP).

1. Laser back-facet and bias alarm functions are customer-use
options that are not required for normal operations of the transmit­ter

and are normally used during manufacture and for diagnostics.
The output will optionally be either a logic signal or an analog volt­age. All alarm, select, and enable signals are active-high.

Absolute Maximum Ratings

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 operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
