Optical Switch With GSM

“Optical Switch with GSM has an extremely low noise, low insertion loss. It also adopt MCU intelligent control technology to make the performance better than others.

The major problem comes in CATV that we don’t able to know whether our line is cut or okay. So to resolve this problem we add GSM Module in Optical Switch. Benefit of GSM module is that whenever any Optical Input either its Input A or Input B cut, the User will get the message regarding it. And to make it more convenient we also add one more function, in which our customer will get the message when it will be restored.”
