Product Overview for Optical Line Protection:
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 larger 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 shortens the recovery time from hours to milliseconds.
Function of OLP:
- Optical line automatic switching protection
- Real-time power monitoring
- Support automatic switching of primary and secondary routes
Highlights of OLP:
- Support automatic switching of primary and secondary routes
- Support manual and automatic switching modes
- Low switching time: <30ms
- Low insertion loss: <5.5 dB
- Support automatic return to the Primary
- Support manual and automatic working mode settings
- Support for switching threshold settings
The optical line protection switch provides both manual and automatic switching modes. In manual mode, the system switches the optical path only based on the commands from the user.
In automatic mode, the system switches based on the detected power level and the preset threshold. Under automatic mode, the system can be set to revertive or non-revertive modes.
Under revertive mode, the system switches back to the working path automatically after the fault condition is cleared. Under non-revertive mode, the system does not switch back.
