Full C-band tuning (89 channels at  50 GHz spacing) 

High, flexibly adjustable output  power, from 9 to 13 dBm 

Low power dissipation, typically  < 2.2 W at 75°C 

High side-mode suppression ratio  > 40 dB

Dark tuning by reverse biasing the  integrated optical amplifier 

Compact, low-profile, hermetic  laser package with internal optical  isolator 

Integral wavelength locker,  allowing stabilization to within  ±2.5 GHz over life, compatible with  50 GHz ITU grid spacing 

Polarization maintaining fiber  pigtail
