The world's first 5-nanometer silicon processor. IBM Research experts in collaboration with partners from GlobalFoundries and Samsung have created the first working processor made in 5 nm technology. This is another revolutionary achievement of the same team that implemented a 7 nm test processor in 2015. This means a tremendous progress in the miniaturization of integrated circuits. The latest 5-nanometer chip was made using innovative technology. The lithography employed for the production of the chip was using extreme ultraviolet (13.5 nm - EUV). The new technology node required the use of narrower light beams to create the appropriate semiconductor structure. EUV ensures a huge improvement compared to the currently used ArF (argon fluoride) lasers with a wavelength of 193 nm (FUV - far ultraviolet). The use of the Gate All Around (GAA) process has enabled engineers to place as many as 30 billion transistors on a chip like a human fingernail. The current technology, based on FinFET transistors, has been further miniaturized using silicon and silicon germanium nano-sheets.
The world's first 5-nanometer silicon chips
In practice, the performance of systems based on the new chips could increase by 40 percent, compared to the current 10 nm leading solutions, while maintaining the same power consumption. Alternatively, it is possible to save energy by creating systems at the same performance level as the current 10 nm devices, reducing the power demand by 75% . The new chip introduced by IBM can be widely used in the future, especially in the fields of mobile and wearable electronics, in servers, as well as in IoT and machine learning systems.
Currently, the leading solutions are based on 10 nm processors, such as the Snapdragon 835. Samsung announced that it plans to begin production of 7 nm processors in early 2018, while 5 nm chips are expected on the market in 2020.
Broadband amplifiers in shared antenna systems. House/building broadband amplifiers are used in shared antenna systems (MATV/CATV) to distribute antenna signals within passive networks. They compensate the attenuation of the distribution networks caused by splitters, taps, cables and antenna outlets. Depending on the needs, the installer can select forward-path-only models, or amplifiers equipped also with return path/channel (needed for providing Triple Play services - TV, Internet, telephone).
TERRA company's products enjoy a high level of trust among installers. The real parameters are often better than provided in the data sheets. Full use of modern electronics and information technology allows the company for precise measurements of parameters and control of product quality, including tests in climate chambers.

Fiber optic connections in homes. L7102 is the first choice cable for applications in homes/apartments. Its high mechanical strength and small dimensions allow for easy and safe installation of the cable while maintaining a good level of aesthetics.
In the case of providing only one optical connection, an alternative to employing a fusion splicer and installing an optical box/outlet is the application of the Ultimode FAST L5711 or L5712 quick assembly connector. The connector can be inserted directly into the active fiber optic device.
To terminate the fiber with the quick assembly connector, the installer needs stripper for flat cables (SP-001 L5906), fiber optic stripper L5905, dust-free Kim-Wipes L5913, IPA solvent cleaner L5915, and a fiber cleaver, e.g. L5801. The required operations include: removing the outer coating of the cable at a distance of about 50 mm to reach the fibers (the second fiber should be cut off), removing the 250 μm coating on a section of about 20 mm, cleaning the fiber and cut it to 27 mm length. The prepared fiber, together with the cable, should be inserted into the connector (the fiber may be slightly bent) and clamped.
The L7102 cable and L5711 quick assembly connectors also provide perfect solution for installing patch cords connecting optical outlets with active devices. The installer can make patch cords of any lengths in a short time, and test them with the L5935 visual fault locator.
How to display high quality video on multiple TVs/monitors? 4K splitters allow users to display 4K video content on multiple UHD televisions or monitors. They are needed in the case of electronics stores, conference venues, modern video surveillance systems.
Signal-HD HDMI 2.0 splitter 1x4 H3215 enables the user to connect 4 modern televisions/monitors to a source of high-definition signal, both with HD/Full-HD or 4K resolution (up to 4k x 2k @ 60 Hz). The amplified output signals can be transmitted via HDMI 2.0 cables over distances up to 15 m. 4K video is currently used in modern CCTV systems, e.g. those employing K22165 NVR (4K@30Hz).

Several series of HD-TVI cameras. The range of HD-TVI cameras is still expanding, not only by new models but also with new series. The new series are characterized by greater transmission range, higher resolution, and/or greater immunity to interference. Below there is a comparison of the most popular series.

Easy IP 3.0 - Hikvision cameras with H.265 video compression. DIPOL has introduced a new series of Hikvision IP cameras, Easy IP 3.0. The series features excellent parameters for affordable price. Some cameras of the series offer the latest H.265+/H.265 compression algorithms, Dark Fighter (Ultra-low-light) technology ensuring improved color rendition and image quality in low-light conditions, and advanced image analysis tools. In addition to the basic analytics such as detection of crossing a virtual line and detection of intrusion into an area, the cameras can detect faces, unattended (left) luggage or other objects, attempts to take some objects. These features allow for applications in advanced video surveillance projects.

Compared with H.264, H.265 can reduce by half the data stream, which translates into proportional savings of the disk space or into extended data retention time. H.265+ and H.264+ are Hikvision standards based on the original systems and optimized for CCTV applications. They further minimize the streams in typical video surveillance scenarios.
The markings of cameras from Easy IP 3.0 series contain 2 as the first digit and 5 as the last digit, as well as FWD string (meaning slot for a memory card and WDR function), e.g.: DS-2CD2135FWD-IS.
