New Cables for High-Speed Structured Cabling Systems and Data Processing Centers The article presents new designs of high-category LAN cables with improved consumer properties and also describes the advantages of LAN cables with a shaped sheath. The characteristics of Cat. 6A LAN cables (Odeskabel’ Public Joint-Stock Company) are superior to standard requirements, and this cable is suited for high-speed applications.

Mobile VSAT: No Problems Today The advantages of small-size satellite terminals operating in the Ku and Ka ranges through Russian and European satellites are obvious: high speed at low cost and tariffs. Most customers are OK with the stationary version of the VSAT terminal, which is mounted on the wall or roof of a building. However, today in Russia there is a rapidly growing demand for mobile satellite channels for on-line transmission of a heavy content under field conditions.

Biometric Identification: Whether Expectations will Be Satisfied?
It seems that nothing can be more reliable and convenient than identification in biological parameters (fingerprint, iris pattern, voice timbre, or even manner of working), which are unique for each person. These parameters cannot be forgotten, changed, lost, or transferred to another person. Yet, biological identification has not become popular in spite of all its advantages. What are its problems and prospects? Let us address to experts.

Overhead FTTH Network for Private Houses Based on Optical Cable Bundles The article considers a new domestic engineering design – an FTTH cable system for a quarter of private dwellings. The system uses a set of thin bundled optical cables. A high economic efficiency of the system, as well as its high reliability and ease of maintenance, is demonstrated. A new technology of bundling suspended optical fibers is described, and a way of constructing the system by winding thin optical cables on a self-carrying optical cable or on a dielectric rope is discussed.

Milesight IP Cameras with SIP Support Milesight IP cameras, offering a high quality and a high functionality, are new products for the Russian market. The main advantage of Milesight cameras is SIP support. They allow users to “ring” the camera, accept a call from the camera, control the camera by phone, and take images and sound by a videophone from any distance.

At the Cusp of Information Revolution Digital technologies convert TV and video content into the mainstream of mobile media and provide opportunities for cooperation and/or competition of digital on-air broadcasting and wireless broadband access. However, a keen competition on the ultrahigh frequency spectral range goes on.

Biometrical Methods in Cryptography: Problems and Prospects The article is devoted to biometry, which is viewed as an advanced promising mechanism of cryptographic data protection. The application of the human’s unique biometric parameters to avoid unauthorized access to
confidential information presents some difficulties and has certain
limitations. Nevertheless, a biometric system in many parameters
is a suitable and reliable way to provide security of media.

Diagnostics of Digital Access Networks Based on Copper Cables Diagnostic methods for digital access networks are considered. The networks are based on copper communication cables and intended for symmetric and asymmetric xDSL technologies. The authors provide practical guidance on the evaluation of digital lines using different instrumentation.

Testing of the Subscriber Site of PON The nonuniform distribution of optical losses in subscriber sites adversely affects the stability of home fiber-optic access networks: the number of signal regeneration errors grows and the operational stability of the entire network is disturbed. Thus, careful testing in subscriber sites assembling is of great importance. A method of testing subscriber sites is suggested for measuring tool designers, communications service providers, and operating organizations.

Equipment Control: New Trends Problems arising from the collective operation of equipment from different manufacturers are discussed. A Sealtek-Inspector monitoring and control system is suggested that makes it possible to eliminate main problems and offers additional services. This system was successfully tested and is now used in networks deployed in a number of large local companies.

Conference “Cables and Communication Links”: What is the Use of It? Do we really need conferences in the age of the Internet, when any desired information can be found in the Web for several minutes? I say “yes,” since the Internet cannot replace face-to-face contacts and, moreover, information available from the Internet is incomplete. Specifically, do we need the conference “Cables and Communication Lines?” It will suffice to take part in it at least once to answer in the affirmative.
