A link group configuration method includes obtaining first status information of M links between a source end device and a receive end device, where the first status information indicates a status of a differential delay between any two of the M links, obtaining first capability information of the receive end device, where the first capability information indicates a first capability of performing differential delay compensation on the M links by the receive end device, grouping N of the M links into a first link group based on the first status information and the first capability information, and sending first configuration information to a second device, where the first configuration information includes information used to indicate the first link group.

Power distribution modules are configured to distribute power to a power-consuming component(s), such as a remote antenna unit(s) (RAU(s)). By “hot” connection and/or disconnection, the power distribution modules can be connected and/or disconnected from a power unit and/or a power-consuming component(s) while power is being provided to the power distribution modules. Power is not required to be disabled in the power unit before connection and/or disconnection of power distribution modules. The power distribution modules may be configured to protect against or reduce electrical arcing or electrical contact erosion that may otherwise result from “hot” connection and/or connection of the power distribution modules.

Provided is a distributed antenna system (DAS) for multi-frequency band and multi-carrier equipped with an open radio access network (O-RAN) remote unit (RU) according to an O-RAN technology standard for building a next-generation radio infrastructure. To this end, the DAS for multi-carrier and multi-frequency band based on an O-RAN standard includes an O-RAN RU connected to a fronthaul network according to an O-RAN split option specification of base station transceiver systems (BTSs), and including a plurality of O-RAN RUs to accommodate a plurality of carriers and a plurality of frequency bands; and a channel combiner to which outputs of the plurality of O-RAN RUs are combined.

Premises apparatus and methods for providing aggregated high-bandwidth, low-latency data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

In a system for converting digital data into a modulated optical signal, an electrically controllable device, including a modulator having one or more actuating electrodes, provides an analog-modulated optical signal that is modulated in response to output data bits of a digital-to-digital mapping. A digital-to-digital conversion provides the mapping of input data words to the output data bits. The mapping enables adjustments to correct for non-linearities and other undesirable characteristics, thereby improving signal quality.

Systems to extend signal transfer used with a camera device comprise a first location station with a first receiver and a second receiver. The first receiver receives wireless signals from a user device that are changed and sent through a fiber optic cable to a second location station. The second receiver receives signals through the cable from the second location station, which signals are changed to wireless signals output to a user device. The second location station comprises a third receiver that receives from the cable from the first location station, which signals are changed to wireless signals output to a camera device. The second location comprises a fourth receiver that receives wireless signals from the camera device, which signals are changed at the first location to signals sent through the cable from the second location station to the first location station.
