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.

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).

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.
2. NUC = no user connection.

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.
