Optical Line Protection (OLP) system is a new optical line protection subsystem developed with advanced technology of dynamic and synchronous optical switches. When communication quality is lower or equipment breaks down due to accidental fracture or bigger loss of optical fiber in the optical transmission line, the OLP system can switch the primary line to the secondary line within a short time, to ensure normal operation communication of line, which effectively prevent fiber or equipment fault and shorten the recovery time from hours to milliseconds.

- The system can automatically switch the signal to the optical fiber of the protection path when performance deterioration or blocking of workpath is detected.
- Applicable to all kinds of optical communication system
- Support line protection of dual fiber and single fiber transmission network
- Support multiple working modes of automatic or manual switching
- Supporting real-time monitoring of main and backup routes
- Fast response: switching time<20ms
- Support automatic non-return and automatic return functions, automatic return time can be set to adapt to a variety of application scenarios
- Support panel button operation. The system can be operated by button on site without management card OLP card and network management card are independent of each other and have no influence on each other
