Data center interconnections, which encompass WSCs as well as traditional data centers, have become both a bottleneck and a cost/power issue for cloud computing providers, cloud service providers and the users of the cloud generally. Fiber optic technologies already play critical roles in data center operations and will increasingly in the future. The goal is to move data as fast as possible with the lowest latency with the lowest cost and the smallest space consumption on the server blade and throughout the network. Accordingly, it would be beneficial for new fiber optic interconnection architectures to address the traditional hierarchal time-division multiplexed (TDM) routing and interconnection and provide reduced latency, increased flexibility, lower cost, lower power consumption, and provide interconnections exploiting scalable optical modular optically switched interconnection network as well as temporospatial switching fabrics allowing switching speeds below the slowest switching element within the switching fabric.

The described technology is generally directed towards using a frequency-separated band as a supplementary uplink band for a new radio downlink band that cannot operate as a time division duplex band and otherwise has no paired uplink band. The paired bands are separated in frequency, yet operate in the time division duplex mode. The supplementary uplink for New Radio facilitates coexistence with LTE in the frequency division duplex spectrum.

Gateway apparatus and methods for providing data services (including IoT data services) which leverage existing managed network (e.g., cable network) infrastructure. The disclosed methods and apparatus enable, among other things, delivery of IoT data services in a unified manner via a common portal or IoT gateway (IoTG) which may be both remotely accessed by a user, and remotely controlled/configured by the host network operator (e.g., MSO). In one variant, the premises devices include RF-enabled receivers (enhanced consumer premises equipment, or CPEe) configured to receive (and transmit) OFDM waveforms via a coaxial cable drop to the premises, and interface with the aforementioned IoTG to enable provision of both 5G high-speed data services and lower bandwidth IoT services to the premises, all via a single coaxial cable drop in the exemplary embodiment.

Disclosed are a spectrum allocation method and device for an optical network and a computer storage medium. The method comprises: segmenting a service path of an optical network to obtain at least one path segment; trying to allocate, in sequence, for each path segment of the service path a service processing manner that satisfies a service spectrum requirement; and when the service processing manner satisfies the service spectrum requirement, allocating a frequency used by each path segment on the service path according to the currently allocated service processing manner of each path segment of the service path.
