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.
Highlight:
Support automatic switching of primary and secondary routes
Support manual and automatic switching modes
Low switching time <30ms
Low insertion loss: <5.5dB
Support automatic return to the Primary
Support manual, automatic working mode settings
Support for switching threshold settings
Fuction:
Optical line automatic switching protection
Real-time power monitoring
Support automatic switching of primary and secondary routes
Optical Line Protection switch provides both Manual and Automatic switching mode. In Manual mode, the system switches optical path only based on the commands from user.
In the Automatic mode, the system switches based on the power level detected and the preset threshold. Under automatic mode, the system can be set to be 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. The OLP models fit HT6000 Series CH04, CH08, CH20 Chassis.
