Apparatus and method for fiber optic link with built-in test
First Claim
1. An optical component, comprising:
- a signal source adapted to output a first combined optical signal having a first optical signal portion of a first frequency and a second optical signal portion of a second frequency, the first frequency being substantially greater than the second frequency; and
a controller operatively coupled to the signal source and being adapted to induce the signal source to output the first and second optical signal portions, the first optical signal portion being associated with a main communication function and the second optical signal portion being associated with a monitoring function.

Abstract
Apparatus and methods for fiber optic links having a built-in test are disclosed. In one embodiment, an optical component includes a signal source, and a controller operatively coupled to the signal source. The signal source is adapted to output a first combined optical signal having a first optical signal portion of a first frequency and a second optical signal portion of a second frequency. The first frequency is substantially greater than the second frequency. The controller is adapted to induce the signal source to output the first and second optical signal portions, the first optical signal portion being associated with a main communication function and the second optical signal portion being associated with a monitoring function.

24. A method of operating an optical system, comprising:
-
transmitting a combined optical signal from a single optical signal source, the combined optical signal having a first portion characterized by a first frequency and a second portion characterized by a second frequency, the first frequency being substantially greater than the second frequency; receiving the combined optical signal; separating the first and second portions; processing the first portion to derive a primary data signal; and processing the second portion to derive a health data signal. - View Dependent Claims (25, 26, 27, 28, 29, 30)
