Embodiment approach

[0030] As used herein, the term "about" means that amounts, dimensions, formulations, parameters and other variables and characteristics are not and need not be exact, but may be approximate and / or larger or smaller as desired, reflecting tolerance Differences, conversion factors, rounding and measurement errors, etc., and other factors known to those skilled in the art. When a value is described as being about or approximately equal to a number, the value is within ±10% of that number. For example, a value of about 10 refers to a value between 9 and 11, inclusive. When the term "about" is used to describe a value or endpoint of a range, it is to be understood that the disclosure includes the specific value or endpoint to which reference is made. Whether or not "about" is stated in this specification as an endpoint of a value or range, such value or endpoint of a range is intended to include both embodiments: one modified with "about" and one not modified by "about". It will...

[0253] The following examples illustrate the preparation of a representative curable secondary coating composition, cured products made from the curable secondary coating composition, and multi-mode coating of the cured product of the curable secondary coating composition. Fiber properties. Corresponding properties of multimode optical fibers with comparative secondary coatings are also presented.

[0254] measurement technology. The measurement techniques described below were used to determine the properties of the primary and secondary coatings.

[0255] Tensile properties. The curable secondary coating composition was cured and constructed in the form of cured rod samples for measurement of Young's modulus, tensile strength at yield, strength at yield, and elongation at yield. By injecting the curable secondary composition into a tubes to prepare solidified rods. Using Fusion D bulb (Fusion D bulb) at about 2.4J / cm 2 Dose cured stick samples (measured by Light Bug mo...

Abstract

The present description provides reduced-diameter multimode optical fibers. The optical fibers include a reduced-diameter glass fiber and / or reduced-thickness coatings. The overall diameter of the optical fibers is less than 210 [mu]m and examples with diameters less than 160 [mu]m are presented. Puncture resistant secondary coatings enable thinning of the secondary coating without compromising protection of the glass fiber. The optical fibers are suitable for data center applications and features high modal bandwidth, low attenuation, low microbending sensitivity, and puncture resistance in a compact form factor.

Description

[0001] This application claims priority to U.S. Provisional Application Serial No. 62 / 809,234, filed February 22, 2019, which is hereby based upon and is hereby incorporated by reference in its entirety. technical field [0002] This disclosure pertains to optical fibers. More specifically, the present disclosure pertains to multimode optical fibers. Most particularly, the present disclosure relates to reduced diameter multimode optical fibers characterized by high modal bandwidth and high puncture resistance. Background technique [0003] Data centers (DCs) are continually grappling with the challenge of delivering more bandwidth, and a key part of that effort will be the deployment of higher-capacity interconnects and fiber optic cables with higher bandwidth densities. Proposed technologies to achieve capacity growth include higher line rates, advanced modulation formats, wavelength-division multiplexing, space-division multiplexing, and reduced-diameter optical fibers. ...
