1. Summary
TPT85001550 series external modulation CATV 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.
2. Characteristic:
High index: Original system optimized control technology, offers excellent CNR, CTB, CSO & SBS index.
Flexibility: Original SBS critical value 13, 16, 18 adjustable at spot, it can fit for different network.
Reliability: Imbedded double power supplies, switch automatically. Machine case temperature control automatically(ATC)
High quality: Intuitionistic Optic Modulation Intensity(OMI)display.
