Method for selecting wide-band multimode fibers from a single wavelength characterization

An apparatus configured for injecting and measuring a pulsed light of a single wavelength into one or more wide-band multimode optical fibers and a non-transitory computer-readable carrier medium embodying and storing a computer program that is executable in a computing device, the program comprising:

• program code for selecting wide-band multimode optical fibers from a single wavelength;
• program code for obtaining a first DMD plot from one or more optical fibers injected with the pulsed light of a single wavelength using a measurement of dispersion modal delay (DMD) carried out on said multimode optical fiber at a first single wavelength (λ1), the MD plot comprising a plurality of traces each recorded at a different radial offset value r, from an axis of said multimode optical fiber where r=0 to a radial offset value r=a, where a is the core radius of said multimode optical fiber,
• program code for obtaining from the first DMD plot, at least one first multimode fiber specification parameter (P1) at said single wavelength, and
• for each multimode optical fiber:
• program code for obtaining from the first DMD plot, a curve representative of a radial offset delay of said multimode optical fiber, called ROD curve, as a function of the radial offset value r, 0≤r≤a;
• program code for applying a linear fit on the ROD curve for at least one radial offset value range (A, B, C);
• program code for obtaining from said linear fit applied for each radial offset value range, a radial offset delay slope defined as ROD slope (sA, sB, sC);
• and selecting the multimode optical fibers meeting a first predetermined specification criterion (CP1) for said at least one first multimode fiber performance parameter (P1), and for which said at least one computed ROD slope meets at least one predetermined slope criterion (CROD1, CROD2).
