The OFP-4010, available from IRT Electronics , is a magnetic latching 4 port changeover optical switcher using a high performance optical relay and optical level detectors. It is suitable for switching optical signals being run over single mode optical cable.
Features of the OFP-4010 changeover optical switcher include:
- Automatic switching when optical level falls below a settable preset limit
- External momentary Set/Reset control
- No path change on power fail
- Local or remote control
- Front panel LED status indicators
- Optional plug in SNMP monitoring and switching module
Optical detectors measure the optical power level and automatically switch the optical relay when signal strength falls below a dip switch selectable power level threshold set from 5dBm to 30dBm in 5dBm steps. Local switching is possible using front panel push button switches. Remote switching is possible using external normally open or normally closed alarms.
The OFP-4010 changeover optical switcher is ideally suited to applications where a simple choice between two inputs or outputs is required and may be easily driven by detector circuits for automatic path selection. Remote indication of tally and alarms are provided for integration into central alarm and monitoring systems.
An optional SNMP (Simple Network Management Protocol) plug-in module is available for remote monitoring and control when used in conjunction with IRT’s frame fitted with SNMP capability. The OFP-4010 changeover optical switcher is designed to fit IRT’s standard Eurocard frames and may be used alongside any other of IRT’s optical fibre Eurocards.
