Patent number: 8768129Abstract: 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 figure-of-merit (FOM) 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 ?m2 and about 170 ?m2; and an index profile having a figure of merit (FOM) frontier distance less than about 0.7 dB.Type: GrantFiled: September 21, 2011Date of Patent: July 1, 2014Assignee: OFS Fitel, LLCInventors: David Wayne Peckham, Robert Lee Lingle

Patent number: 5905838Abstract: Simultaneous dense WDM operation in both the 1310 nm and 1550 nm transparency windows of silica-based optical fiber, is enabled by a fiber design providing for nulled dispersion within a critically positioned wavelength range. Design provides for values of dispersion in both windows sufficiently low for desired per-channel bit rate, and, at the same time, sufficiently high to maintain effects of non-linear dispersion within tolerable limits for WDM operation. Fiber fabrication and system design are described.Type: GrantFiled: February 18, 1998Date of Patent: May 18, 1999Assignee: Lucent Technologies Inc.Inventors: Arthur F.
