EMTX1500 series external modulated optical transmitter accords with current international industry technique. The whole unit light source adopts narrow bandwidth, low noise, continuous wave DFB laser, which is propitious to reduce the influence of dispersion. The whole unit signal modulation adopts CATV special LiNbO3 external modulator of American company.
Features
1) Output from 3dBm ~ 10dBm, and single or dual out for the user’s choice.
2) Both the external modulator and laser are imported from the United States or Japan.
3) Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR when the CNR is in high standard.
4) Perfect SBS suppress circuit and adjustable SBS in 13, 16, 18, suitable for different types of CATV net.
5) AGC and MGC control.
6) Internal double power which can be switched automatically.
7) Automatically shell temperature control.
