FEATURES
Continuous Wave (CW) Light Source for DWDM system
Output Power: 16dBm
Available at L-band ITU-T Wavelengths between
1570.416 to 1608.329nm
Built-in TEC, Thermistor, Monitor PIN PD and Optical Isolator
Polarization maintaining (PANDA) fiber
APPLICATIONS
10 and 40 Gb/s long haul DWDM Transmission systems.
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
LiNbO3 modulators). The device comes in "butterfly" type, 14-pin package, and operates
between 0 to 70C.
