Manufacture of bend insensitive multimode optical fiber
A method of assembling a preform for a bend-insensitive multimode optical fiber (bimmf), includes providing a multimode core rod, a glass overclad tube, and a trench tube of down-doped quartz glass with a depressed refractive index sufficient to obtain a desired trench depth in a refractive index (ri) profile of a drawn fiber. The core rod is placed inside the trench tube, and the trench tube and the core rod are placed inside the overclad tube to define the preform.
