External Modulated CATV Optic Fiber Laser Transmitter EMTX1527

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 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 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.

8. 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.

9. SNMP management system.

10.The transmitter provides RJ45and RS232 standard interface for the connecting the computer and monitoring.
