Features

1. OTE1500 1550nm External Modulation Optical Transmitter (Wavelength Adjustable) is mainly applied in WSM system, Optical Insertion, the upgrade and extension of modulation and networks. The range is ±1.6nm, to 64 steps, each 0.05nm.
2. Output from 3dBm ~ 10dBm, and single or dual out for the user’s choice.
3. Both the external modulator and laser are imported from the United States or Japan.
4. Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.
5. Perfect SBS suppress circuit and adjustable SBS in 13, 16, 18, suitable for different types of CATV net.
6. AGC and MGC control.
7. Internal double power which can be switched automatically.
8. Automatically shell temperature control.
9. 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.
10. SNMP management system.
11. The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
