The OP7824 is a digital I/O conditioning board designed to fit in the back slots of the OP7000 chassis.
The board holds 16 optical transceivers and converts 16 logic signals into fiber optic signals (transmit channels). Hence it ensures optical digital output isolation between the OPAL-RT simulator and the unit under test.
The transceivers are compatible with plastic optical fiber cables (650nm wavelength). Their frequency range is DC to 25 MHz, corresponding to a 50 Mbps baud rate, for distances up to 50 meters. The absolute minimum for transmission (Tx) high and low pulse width is 20ns.
This frequency range means the board can be used as a standard digital output card with isolation (DC mode), or for low-speed communication protocols.
Each channel implements the Tx part of the OP7820 channel circuit.
The OP7824 fiber optic module must be inserted in the back of the OP7000 simulator, making sure that the board is properly aligned using the guide tracks before pressing it into place.
The corresponding front slot may be empty or may hold an OP7353 monitoring board.
The front plate features 16 transmit (Tx, output) transceivers.
The plastic optical fiber cable must hold a VersaLink termination. One cable is required for each transceiver connection.
