1550nm Direct Diode Modulation CATV Optic Transmitter
| Product Description
Direct modulation will lead to high laser chirp (Laser’s bias current is modulated by signal and the optical spectrum FM’s). Laser chip will interact with dispersion effect caused by standard single mode fiber (SMF-28), which will generate serious CSO distortion . This distortion will become more serious with the increase of transmission distance, bandwidth and channel number.
Today we can maintain acceptable signal quality while transmitting an analog and digital full channel signal with transmission distance≤15Km or transmitting digital load with transmission distance≤40Km.
