External Electromagnetic Field Effect on Full-Dielectric Optical Cables A delusion is circulated that external electromagnetic field does not
effect full-dielectric cables. Meanwhile the electromagnetic field of light
that is propagating along the optical fiber reacts with the external field. This article considers some external electromagnetic field effects on the direct buried
or suspended on power transmission line supports optical cable
without metallic parts in its construction.

High Availability Optical Ring. Increasing the Sla Level of Cloud Provider Due to high rates of growth of Russian IT autosourcing volume and cloud operators services its necessary to unambiguous record the quality of provided service, warranties and indemnities size. In practice it is possible to solve this problem only by an SLA (Service Level Agreement) mediant that specifies the cloud provider
and client relationship.

Photonics Networks. Russian Communications Technologies Roadmap To achieve a communication and information technology development level breakthrough Russia must create a national telecommunication brand and develop a telecommunication equipment complex for all-optical communication networks. Its leader should be the State. Besides investment contribution the State has to assume some organizational measures to support home telecommunication equipment producers.
