Optical Transmitter feature:
1. Optical Transmitter adopt DFB laser, narrow Spectrum, good linear and high output power.
2. Optical Transmitter adopts RF power digital automatic process technology, auto-adjust RF driving power according to the input RF signal level and channel number(15~84) to make the C/CSO, C/CTB and C/N in the best condition,
3. Advanced multi-frequency point pre-distortion technology with GaAs devices optimize C/CTB and C/CSO value.
4. Optical Transmitter adopt Ortel, AOI laser.
