Advance Data Sheet, Rev. 1 June 2001 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 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 ■ Laser bias monitor alarm ■ Module enable/disable input 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 Telcordia Technologies* GR-253-CORE requirements and the ITU-T 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 wavelength 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. * Telcordia Technologies is a trademark of Telcordia Technologies, Inc. CW20P-Type CW Tunable, Wavelength-Stabilized Laser Module Advance Data Sheet, Rev. 1 June 2001 Module Processing Pin Information 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. Table 1. Pin Descriptions 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 Cleaning Fiber-Optic Assemblies Technical Note (TN95-010LWP).

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. 2. NUC = no user connection. 2 Agere Systems Inc.
