Abstract
Certain embodiments of the invention may include optimized trench-assisted ultra large area (ULA) optical fibers. According to an example embodiment of the invention, a trench-assisted optical fiber, optimized for microbend frontier (MBF) performance is provided. The optical fiber includes a core region having a longitudinal axis, a shelf region surrounding said core region, a cladding region surrounding said shelf region, said core and shelf and cladding regions configured to support and guide the propagation of signal light in a fundamental transverse mode in said core and shelf regions in the direction of said axis. The optical fiber further includes a core effective area (Aeff) of between 135 μm2 and about 170 μm2; a relative effective index difference (Neff) of greater than about 0.08%; a loss at 1550 nm of less than 0.180 dB/km; and a microbend frontier (MBF) distance of less than about 90%.
