Abstract
Fiber optic data networks have a first network device that has a first optical transmitter that is configured to transmit an optical signal having a first wavelength. A fiber optic communications channel provides a data connection between the first network device and a second network device. The network further includes a second optical transmitter that is configured to transmit an optical signal having a second wavelength that is different from the first wavelength. A coupling device is provided that is configured to inject the signal having the second wavelength that is output by the second optical transmitter onto the fiber optic communications channel. These fiber optic data networks may carry control data in real time on the same optical fibers that are used to carry the normal network traffic.
