  • Publication number: 20250007605
    Abstract: Methods for estimating the Effective Modal Bandwidth (EMB) of laser optimized Multimode Fiber (MMF) at a specified wavelength, ?S, based on the measured EMB at a first reference measurement wavelength, ?M. In these methods the Differential Mode Delay (DMD) of a MMF is measured and the Effective Modal Bandwidth (EMB) is computed at a first measurement wavelength. By extracting signal features such as centroids, peak power, pulse widths, and skews, as described in this disclosure, the EMB can be estimated at a second specified wavelength with different degrees of accuracy. The first method estimates the EMB at the second specified wavelength based on measurements at the reference wavelength. The second method predicts if the EMB at the second specified wavelength is equal or greater than a specified bandwidth limit.

  • Publication number: 20240430009
    Abstract: An apparatus having at least two user interfacing I/O data communication transceivers. The I/O transceiver utilizes either electrical or optical signaling based on user preference with each I/O transceiver being electrically connected back-to-back to a WDM transceiver in the apparatus. The optical media dependent interface of each WDM transceiver has a uniquely specified wavelength and optical ports of the WDM transceivers are connected to the corresponding wavelength ports of a WDM device. The discrete optical wavelengths are multiplexed or demultiplex onto a duplex pair of optical fibers by means of the WDM device in order to convert the interfacing I/O signals to the appropriate optical wavelengths to facilitate pre-configured WDM optical communications.
