Abstract
A fiber optic conversion method is provided that includes receiving a first electrical signal. A second electrical signal is received. The first and second electrical signals are compared. A float signal is generated when the first and second electrical signals comprise substantially a same electrical signal. A determination is made regarding whether optical signals are being received. A light signal is generated while optical signals are being received. A driver mode is entered in response to the float signal and the light signal being generated simultaneously. The driver mode is remained in while the light signal is being generated.
Claims21
A fiber optic conversion method, comprising:
- receiving a first electrical signal;
- receiving a second electrical signal;
- comparing the first and second electrical signals;
- generating a float signal when the first and second electrical signals comprise substantially a same electrical signal;
- determining whether optical signals are being received;
- generating a light signal while optical signals are being received;
- entering a driver mode in response to the float signal and the light signal being generated simultaneously;
- and
- remaining in the driver mode while the light signal is being generated.
A fiber optic converter, comprising:
- a bus connector operable to receive input signals from a bus and to transmit output signals to the bus;
- a driver coupled to the bus connector, the driver operable to provide output signals to the bus connector for transmission to the bus when the fiber optic converter is in a driver mode;
- a comparator/receiver coupled to the bus connector, the comparator/receiver operable to receive input signals from the bus through the bus connector when the fiber optic converter is in a receiver mode;
- a voltage adjustment circuit coupled to the bus connector, the voltage adjustment circuit operable to cause the input signals from the bus connector to float when signals are not being received over the bus at the bus connector;
- a mode selector coupled to the comparator/receiver, the comparator/receiver further operable to compare the input signals received from the bus connector and to provide a float signal to the mode selector when the comparator/receiver determines that the signals are floating;
- a light monitor coupled to the mode selector, the light monitor operable to determine whether or not the fiber optic converter is receiving optical signals and to provide a light signal to the mode selector when the light monitor determines that the fiber optic converter is receiving optical signals;
- and
- the mode selector operable to receive the float signal from the comparator/receiver and to receive the light signal from the light monitor and to place the fiber optic converter into either the driver mode or the receiver mode based on the presence of the float signal and the light signal.
A fiber optic conversion system, comprising:
- a computer-processable medium;
- and
- logic stored on the computer-processable medium, the logic operable to receive a first electrical signal, to receive a second electrical signal, to compare the first and second electrical signals, to generate a float signal when the first and second electrical signals comprise substantially a same electrical signal, to determine whether optical signals are being received, to generate a light signal while optical signals are being received, to enter a driver mode in response to the float signal and the light signal being generated simultaneously, and to remain in the driver mode while the light signal is being generated.
