CW20P-Type

CW Tunable, Wavelength-Stabilized Laser Module

Applications

■ SONET/SDH extended-reach

■ Long-haul, very dense, wave-division multiplexing

(DWDM)

■ High-speed data communication

■ Flexible wavelength systems

Description

The CW20P-type laser modules are designed for use

in transmission systems and high-speed data com-

munication applications. The device supports

20 wavelengths. The module uses an RS-232 inter-

face to adjust various module functions such as

wavelength. In addition, the interface provides acces-

sibility to the alarm and monitor outputs.

Offering multiple channel selections and SONET/SDH compat-

ibility, the CW20P-Type CW DBR Laser Module is manufac-

tured in a 24-pin metallic DIP with a polarization-maintaining

fiber (PMF) pigtail.

The modules meet all present Telcordia Technolo-

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

G.957 and G.958 recommendations. The modules

are also suited for extended distance data and net-

working applications when used in conjunction with a

lithium niobate modulator.

Features

■ Tunable up to twenty ITU-T 50 GHz channels

■ For use with lithium niobate modulators

■ Integrated Etalon stabilizer

—Replaces external wavelength lockers

The CW20P uses a 1.5 µm distributed Bragg reflec-

tor (DBR) laser with an integrated wavelength stabi-

lizer. By integrating the wavelength stabilizer with the

DBR laser chip, the device offers a compact, cost-

effective solution for low-dispersion transmission.

Devices are provided at wavelengths that are com-

patible with the ITU-T wavelength standards at

200 GHz, 100 GHz, and 50 GHz. The package also

contains a thermoelectric cooler, thermistor, back-

facet monitor, and optical isolator. The laser module

requires 5 V, –5.2 V, and 3.3 V.

■ 1528.77 nm to 1610.0 nm wavelengths

■ Compact design

■ Remote programmability

■ Asynchronous serial interface for module communi-

cation

■ High output power, up to 20 mW

■ Low profile, 24-pin package

■ Laser bias monitor alarm

■ Module enable/disable input
