Integrated fiber optic monitoring techniques for a wellsite are provided. A fiber optic cable is provided with a tubular housing having a channel and a plurality of slots, a plurality of optical fibers may be floatingly positionable in the channel for measuring at least one first wellsite parameter and a plurality of optical fibers fixedly may be positionable in each of the slots for measuring at least one second wellsite parameter. The tubular housing is positionable into a wellbore adjacent a tubing therein. Pairs of the fixed and floating optical fibers may be spliced together to perform Stimulated Brillouin measurements.
