External Modulated Optical Transmitter EMTX1500
1550nm External Modulated Optical Transmitter EMTX1500
Description :
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 output ports for user’s choice.
2. External modulator and laser are imported from the United States or Japan.
3. Perfect pre-distortion circuit ensures the best CTB and CSO when 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. Internal double power which can be switched automatically.
6.Internal microprocessor software has the function of laser monitoring, parameter display, fault warning, net management and so on. Once the working parameter of the laser goes out of the fixed value of the software, the machine will warn.
7.The transmitter provides RJ45and RS232 standard interface for connecting computer and monitoring.
8. SNMP management system.
9. AGC and MGC control.
