摘要: Microstructured optical fiber and method of making. Glass soot is deposited and then consolidated under conditions which are effective to trap a portion of the consolidation gases in the glass to thereby produce a non-periodic array of voids which may then be used to form a void containing cladding region in an optical fiber. Preferred void producing consolidation gases include nitrogen, argon, CO2, oxygen, chlorine, CF4, CO, SO2 and mixtures thereof.

摘要: A method of making a multimode optical fiber is disclosed. In one embodiment the method includes calculating a core radius that maximizes the bandwidth of the multimode optical fiber wherein the effect of draw tension is accounted for. The embodiments herein illustrate how core radius can be tuned so the time delay of the outermost guided mode group is reduced. The resultant core radius may be targeted for a value off-nominal from what would be expected for a particular commercial optical fiber type.
