China product 1550nm/1310 FTTH CATV Optical Transmitter with AGC
ST1550 series Advanced type Externally Modulated CATV optical transmitter adopts low noise, narrow bandwidth, and continuous wave laser as its light source. It uses high linearity LiNbO3 external modulator to modulate 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.
