DESCRIPTION
The laser is for a high power (16dBm) CW operation, at selected L-band ITU-T
grid wavelengths. The module includes an optical isolator monitor photodiode, thermistor and a
thermo-electric cooler. This laser is designed for use with external modulation components (such as
LiNbO modulators). The device comes in “butterfly” type, 14-pin package, and operates
