Abstract
A method of transmitting data over a fiber-optic channel, where the data comprises multi-valued bits each having at least three possible values. The method comprises establishing a respective optical characteristic corresponding to each of the possible values. For each multi-valued bit of the data, a pulse is transmitted having the optical characteristic corresponding to the value of the multi-valued bit.
Claims11
A method of transmitting data over a fibre-optic channel, said data comprising multi-valued bits each having one of at least three possible values, said method comprising:
- a) establishing a respective optical characteristic corresponding to each of said possible values;
- b) for each multi-valued bit of said data, transmitting a pulse having the optical characteristic corresponding to the value of said multi-valued bit.
An optical encoder for transmitting data over a fibre-optic channel, said data comprising multi-valued bits each having at least three possible values, said optical encoder comprising:
- a) a control;
- b) a laser driver operated by said control, and providing a mode corresponding to each of said possible values;
- c) at least one laser connected to said laser driver;
- and
- d) an optical multiplexer connected to each of said laser driver;
- said control being configured to receive said data, process each multi-valued bit thereof, and operate said laser driver in the mode corresponding to each multi-valued bit of the data and thereby transmit said data.
