Abstract: Optical systems that employ concentric multi core fibers (MCFs) are discussed. Some of the systems discussed are based on the use of a concentric MCF that has a single mode core, capable of carrying a broadband data signal, and a multimode core, which carries optical signals that do not require as high a bandwidth as the broadband data signal. In one embodiment, the multimode core carries system management data. In another embodiment, the multimode core carries a high power optical signal that provides remote power. In another embodiment, the multimode core carries a pump signal for a downstream fiber amplifier. In yet another embodiment, the multimode core carries an optical signal, for example visible light, that can be used to verify connectivity.

Abstract: A first multimode optical fiber carries a mode division multiplexed (MDM) optical signal. The MDM optical signal is transmitted into a second multimode fiber from the first multimode optical fiber. The first and second multimode fibers are coupled via a fiber connector. The lateral offset between the two fibers at the connector is less than 2 μm.

Abstract: The invention is directed to the characterization of an optical channel, such as an optical fiber, in an optical network. The method includes calibrating a transmitter by measuring its transmitter and dispersion eye closure (TDEC, in the case of non-return to zero optical (NRZ) optical systems or transmitter and dispersion eye closure quaternary (TDECQ, in the case of 4-level pulse amplitude modulation (PAM4) optical systems). That calibrated transmitter is used to characterize the optical channel being tested by providing a measure of its stressed eye closure (SEC) or stressed eye closure quaternary (SECQ). A loss deficit for the optical channel can be calculated by subtracting the SEC or SECQ value from the maximum TDEC or TDECQ value.

Abstract: A cabling arrangement to optically couple data servers to network switches utilizes bidirectional optical fibers (e.g., multi-mode). Some types of cabling arrangements include one or more distribution modules, at least two distribution cables, and a plurality of duplex cables. Other types of cabling arrangement include one or more distribution modules, at least two distribution cables, two configuration modules, a plurality of configuration cables, and a plurality of duplex cables. The cabling arrangement may be passive and/or colorless.
