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 70°C.
