“PROFLEX” PCOO-3027GPI series optical changeover is designed to protect an optical fiber link. The latching optical relay retains it's state during the power outages.
Features
- manual changeover and changeback
- latching optical relay
- currently selected input indication
- GPI outputs to control a slave device
- local and remote control of switching (from GPI and/or "PROFLEX" protocol)
- 1270~1620nm supported wavelengths

Controls and management
PCOO-3027GPI local controls are on the frontal panel:
Buttons
- CHANGE - toggles the optical output between the MAIN and the STBY optical inputs
Indicators
- IN USE MAIN - lit when the MAIN input is provided to the optical output
- IN USE STBY - lit when the STBY input is provided to the optical output
