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

Publication number: 20130243949Abstract: Described is a modular method of making an optical fiber comprising a core and a cladding configured to support and guide a fundamental transverse mode, the cladding including (i) an outer cladding having an index nout less than the index n1 of the core, (ii) an inner cladding having an index n2<nout, (iii) a pedestal having an index n4?nout, (iv) an inner trench disposed between the inner cladding and the pedestal, the inner trench having an index n3<<n4, and (iv) an outer trench disposed between the pedestal and the outer cladding, the outer trench having an index n5<n4 and relatively close to nout. To suppress unwanted HOMs the pedestal is configured to resonantly couple at least one unwanted transverse mode of the core (other than the fundamental mode) to at least one transverse mode of the pedestal.Type: ApplicationFiled: May 14, 2013Publication date: September 19, 2013Applicant: OFS FITEL, LLCInventors: John Michael Fini, Robert Lee Lingle, JR., Yi Sun
