CW22P891

Advance Data Sheet, Rev. 1 June 2001 CW20P-Type CW Tunable, Wavelength-Stabilized Laser Module Applications s s SONET/SDH extended-reach Long-haul, very dense, wave-division multiplexing (DWDM) High-speed data communication Flexible wavelength systems s s Description 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. Offering multiple channel selections and SONET/SDH compatibility, the CW20P-Type CW DBR Las...
