The true value of this patent is based on the following: 1. Measurable cost savings/or improve ROI: deploying optical equipment is increasingly expensive with each successive wave of deployments, typically leading diminishing or longer ROI. 2. Performance: with countries like China companies like the SoftBank investing and exploring Satellite communication, end-to.-end latency could be a deciding factor. 3. Backwards Compatibility: can existing providers cheaply upgrade their existing deployments 4. Standards: the majority of telecommunication providers generally purchase standards compliant infrastructure products to avoid being dependent on a single vendor. Standards, this is not a speedy process---however getting on the features roadmap could massively increase the value of the patent.
Applications: Smart City projects, Saudi Arabia Mega Cities, 5G base-station network densification programs. Data Center expansion programs.
Companies: Data Center USA (e.g. Microsoft, Amazon, Google, Facebook...) and Chinese (Baidu, Alibaba, Tencent) infrastructure providers, Disruptive Telecom Provider (Alice USA), Vendors: Nokia, Huawei, Ciena. Cisco, Infinera.

Coupling of electrical and optical interface in a plug like connection eases the handling of devices that use optical communication techniques, but still need electrical energy to work. The optical interface consists of a waveguide like a fiberglass waveguide and a optical element to emit / receive the light radiation into / from the waveguide. The electrical conductors are arranged coaxial on the outside of the device. This seems to be one of the easiest ways to connect optical and electrical conductors togehther in one part.
Applications: optical networking / transferring of data via optical lines
Companies: Network companies like Cisco, netgear etc.
