TOS2000TOW series optical switch module is featured in short switching time (≤ 8ms) and low loss (≤ 1.5dB), which is mainly used in fiber ring network or redundant standby network. When the main line fails or is lower than the set threshold value, it will automatically switch to the standby line. When the main line returns to normal, it will automatically return to the main line. When device is in the mode of manual forced switching , it can switch to the main line or the standby line as you like.

　　In addition to the optical switching function, the device also have the RF detection function to check the signal quality. When the input optical power is ≥ 0dbm, and in the automatic operating mode, the RF detection function can be turned on. When the RF detection value is lower than the min required value, it can be judged that there is no RF signal in this line, and another line will be detected quickly, If the RF signal in another line is detected to be normal,  the optical switch will turn to another line.  If there is no RF signal detected in another line, the optical switch will not act. To avoid misjudgment, when the input optical power is lower than 0dBm, the device will turn off the RF detection function automatically .

1.It has the function of power-off protection. When the device itself fails or its power supply off, it will automatically remain on the current line before the failure to maintain the operating status of the network.

2.The Optical Switch is featured in short switching time, low loss, with automatic switching and forced manual switching function.

3.Large switching dynamic range

4. With RF detection function( optional).

5.The built-in microprocessor monitors all the operating status parameters of the module and transmits them to the platform through the bus. The platform can monitor and display its operating status through LCD screen. The intelligent function of the platform provides a good internal operating environment for the module, so that the excellence of the module can be brought into play, with high reliability and stability.
