The first optical signal can include a first digital signal modulated onto a first light signal of a first wavelength, the second optical signal can include a second light signal can include a second wavelength different from the first wavelength, and the fourth optical signal can include the first digital signal modulated onto the second light signal. Other embodiments are disclosed.

Abstract: An example apparatus may include an optical splitter apparatus that includes a dual mode fiber having a single mode fiber core embedded in a multi-mode fiber core, a plurality of single mode fibers, and a funnel waveguide coupling the dual mode fiber to the single mode fibers. The optical splitter apparatus may be for use in a passive optical network. The single mode fiber core may be for transmitting downstream optical signals, where the funnel waveguide distributes the downstream optical signals to the single mode fibers. In addition, the single mode fibers may transmit upstream optical signals, and the funnel waveguide may direct the upstream optical signals into the multi-mode fiber core. The optical splitter apparatus may have an asymmetric insertion loss ratio between the downstream optical signals received via the single mode fiber core and the upstream optical signals received via the single mode fibers.

Abstract: Aspects of the subject disclosure may include, for example, a device having an input port and multiple output ports adapted for connection to multiple passive optical network (PON) segments. The device includes an optical power splitting device in communication between the input port and the multiple output ports and adapted to provide divided portions of an optical signal received at the input port to the PON segments via the output ports. The device includes optical delay devices in optical communication between the optical power splitting device and at least a portion of the multiple output ports. The optical delay devices provide distinguishable delay values, that delay the divided portions of the optical signal, the distinguishable delay values facilitating associations of the PON segments to the output ports based on optical time domain reflectometry (OTDR) measurements obtained via the input port. Other embodiments are disclosed.

Abstract: The technologies described herein are generally directed to placing edge hub equipment for virtual radio access networks based on resource availability and performance in advanced networks, such as a fifth generation (5G) network or other next generation networks. For example, a method described herein can include receiving a request to select, for deployment of hub equipment, between site locations, with the deployment of the hub equipment being to connect, in a fronthaul segment, radio unit equipment of the network at a radio location to a backhaul connection equipment. The method can further include, based on the request, the radio location, and the backhaul location, comparing a characteristic of the site locations. Further, the method can include responding to the request with a selected site location that was selected based on a result of the comparing.

Abstract: The technologies described herein are generally directed to the use of fiber optic cables for communication. For example, a method described herein can include moving opposing members of a fiber optic securing clip from an open position to a closed position, wherein the opposing members are spaced apart to receive a first fiber optic strand comprising a bare end. The method can further include, based on the opposing members being in the closed position, securing the bare end of the first fiber optic strand within the fiber optic securing clip comprising optically coupling the first fiber optic strand to an end of a second fiber optic strand.

Abstract: Aspects of the subject disclosure may include, for example, determining distinct timing offsets between an input port and output ports of a multiport optical device. An optical signal is injected at an input port of the device to obtain output signals at the output ports, which are injected into downstream fibers. An optical multipath return signal is received via the input port of the device, including a combination of measured events including reflections, backscatter, or both. A number of similar events expected in the number of downstream optical fibers is calculated to obtain an expected multipath signature based on configuration data. Results of the optical multipath return signal are then compared to the expected multipath signature to obtain comparison results. One of the measured events is distinguished from the others based on the first comparison results and the distinct timing offsets. Other embodiments are disclosed.
