UVOT-ET1550H is a standard external 1550nm Optical Transmitter which adopts low-noise and original DFB laser. With Its perfect pre-distortion circuit to ensure the best CTB and CSO value when the CNR is in high standard. And with hot-plugable power supply.


*  Adopt original USA or Japan brand Laser and modulator 

* Perfect pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard.

*  Perfect SBS suppress circuit and adjustable SBS in 13,16, 19 which suitable for different types of CATV networkl  AGC and MGC control.

*  Internal double power which can be changed automatically.

* Automatically shell temperature control.

*  SNMP management system.

*  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.

*  The transmitter provides RJ45 and RS232 standard interface for the connecting the computer and monitoring.
