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.
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.
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.
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.
