The Optical Protection Switching Coupler (OPSC) is an optical switching device that maintains signal on both outputs in the event of failure of one of two lasers connected to its inputs.
The OPSC in normal operation mode allows the output from two laser modules to pass straight through. In the event of a laser failure, the OPSC automatically activates a switching optical coupler to maintain a reduced power signal on both fibres from a single laser module.
It contains an optical coupler that directs signal from each of two inputs to each of two outputs. When a switching action is initiated by automatic or manual operation, the signal of one input is equally divided between the two outputs.
The module accepts external analog control inputs with adjustable trigger points. There are manual override controls and alarm warning indicators. There are also options for internal optical power sensors on the inputs.
Comprehensive status monitoring of each module is available via the OCM Control Power Module and can be output to remote status monitoring systems. |
