Directly Modulated 1550nm Optical Transmitter 10dBm with AGC

Product Description

Internally Modulated with AGC 1550nm Optical Transmitter

Description

ST1550 series Advanced type Internally Modulated CATV optical transmitter adopts low noise, narrow bandwidth, and continuous-wave laser as its light source. It uses high linearity LiNbO3 internal modulator to modulate the signal. It eliminates the Chirp Effect of 1550nm direct modulation laser. Due to adopting owned system optimized control technology & using top-grade key parts, the machine's technique performance index achieves the standard of same advanced products in the world totally.





Characteristic

1. Low chirp effect, high linearity DFB laser
2. Dual Module, therefore, drive, chirp compensation
3. Laser OMI AGC/MGC
4. Intuitional modulation status display
5. Dual power supply inside the backup. Full-automatically switch
6. Full-automatically control of casing temperature
