Claim Text:
1. In an optical fiber having obstructions in which an obstruction length, a number of obstructions, and a regularity of the obstructions is known, a method comprising: exposing a first location of a core of an optical fiber to incoming actinic radiation, the incoming actinic radiation to inscribe the first location with a grating, the inscribed grating having a finite length; axially moving the optical fiber an incremental distance, the incremental distance being less than the finite length; changing a rotational orientation of the optical fiber with reference to a source of the incoming actinic radiation by a predefined angle of rotation, the predefined angle being a function of the obstruction length, the number of obstructions, and the regularity of the obstructions; and exposing a second location of the core with the incoming actinic radiation.
