	'''The optical ethernet card has to be configured identical to the card installed in the Pegasus/Cheetah System (see (5) below).''' This requires an optical ethernet card that matches the specifications of the card installed in the Neuralynx computer. Unfortunately, the exact optical ethernet card that is installed in many Neuralynx computers is no longer manufactured. Some alternate options have been tested with varying results - we recommend the '''Intel X710-DA2''' optical ethernet card to effectively stream data from the Neuralynx amplifier to the BCI2000 computer. This needs to be compatible with your motherboard. Also, a FiberChannel compatible optical transceiver is required to match the card's SFP ~~output~~ to the fiber cable.
