The OP8216 is an 1U fiber optic channel interface output (TX) or input (RX) depending on selected configuration.

The board holds optical transceivers and converts logic signals into fiber optic signals (transmit channels), and fiber optic signals into digital logic signals (receive channels).  Hence it ensures optical digital input and 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 I/O card with isolation (DC mode), or for low-speed communication protocols.
