A Quasi-Single Mode Optical Fiber for Long-Haul Transmission in Severe Bending Environments
Abstract
We investigated the feasibility of a quasi-single mode optical fiber for low bending losses in long-haul transmission at 1550 nm. The advantage of a quasi-single mode fiber is that for comparable bending losses the relative index difference, delta, can be smaller than the delta in a single-mode fiber. We demonstrated that a quasi-single mode fiber with delta = 0.72% and single-mode cutoff wavelength, lambda sub c, equal to 1630 nm exhibits bending losses as low as the losses in a single-mode fiber with delta = 0.93% and lambda sub c = 1259 nm. Modal noise and modal dispersion effects in the quasi-single mode fiber also were tested and found to be minimal. This paper describes the matched-clad, quasi-single mode fiber and presents the test results.
