14 months Warranty

Our warranty is above industry standards, up to 14 months. This is based on our confidence in the quality of our products and we want to give our customers more protection

Both the external modulator and laser are imported from the United States or Japan.

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, 18,suitable for different types of CATV net.

AGC control.

Internal double power which can be changed automatically.

Automatically shell temperature control.

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.
