IBM scientists on the verge of a great breakthrough.
A supercomputer performing calculations 100x faster than the fastest machine today? This is not a pipe dream but close future. A group of IBM scientists working on a special DARPA project (U.S. Defense Advanced Research Projects Agency) has successfully developed an optical link for quick data transfer between components of supercomputers, operating at 25 gigabits per second and consuming only 24 mW of power. At present, no bus based on electrical network is able to approach to such a performance.
Fiber Optic IC - the future of nanoelectronics?
[www.optics.org]
The use of innovative high-speed circuits produced in 32 nm SOI CMOS technology (silicon-on-insulator with complementary metal-oxide-semiconductor) allowing for maximum speed with minimum power consumption, along with VCSELs (vertical-cavity surface-emitting lasers) and special photodetectors from Sumitomo Electric Device Innovations USA - result in a highly fast and energy-efficient system. The outcome is very favorable - transmission speed increased by 66% and energy consumption reduced by 50%.
Supercomputers of the future will help researchers to solve problems in all fields. The projected computing power should be sufficient for modeling global climate, molecular-level simulations of cells, or engineering new nanomaterials. Such exascale supercomputers are expected by the decade’s end (the exa prefix denotes 10(exp18) floating point operations per second).
The presentation of the high-speed link, entitled "35-Gb/s VCSEL Optic Link using 32 nm SOI CMOS circuits" was given last week in the Anaheim Convention Center in California, at the OFC/NFOEC (Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference). What is interesting, at the same conference engineers of another giant of American telecommunications market - AT & T - presented their project for transmitting data at the rate of 400 Gbps over a distance of 12000 km. The two radically different concepts seem to be extremely important for the future of the ICT market - long-range transmission of an enormous amount of data, and the widely discussed local efficient data exchange within computer circuits.
Transmission over 20 km? Only through an optical fiber.
A corporation wished to connect their computer systems in two locations, 20 kilometers away. The problem was the distance between them. Due to the fact that the security protocols determined to create a direct connection, the corporation decided to lease one fiber from the telecommunications service provider.
Ultimode system allows for data transmission speeds up to 1 Gbps over a 20 km distance
Both locations have been equipped with Ultimode M-207G L11525 Ethernet media converters connected to the existing LANs. Thanks to the optical link between the locations it is possible to exchange information safely between the headquarter and production plant at a data rate rate of 1 Gbps, which greatly improves running the operation of the company.

The mdx420 R82518 digital modulator generates DVB-T RF channel in compliance with EN 300 744 standard, selectable within 110-860 MHz range. Two independent sets of A/V inputs allow for connecting two A/V signals that will be converted into one DVB-T multiplex.
The mt420 R82515 modulator also can inject two A/V signals into the distribution network, but in the form of two PAL channels (selectable B/G/D/K/I/L/Au standards). In both cases, the source signals may come from cameras, multimedia players, computers, DVD players, satellite receivers etc. Any or both of the modulators can be a complement to the set of amplifiers placed on the universal DIN rail R82538 (mountable in a RACK cabinet), or can be installed directly in any suitable RACK cabinet, together with the appropriate power supply.

Application of optical fibers for video surveillance system in a production plant.
The large distance between monitored sites and monitoring center and electromagnetically noisy environment were the key reasons for the deployment of CCTV system based on fiber optic transmission. The main idea was to create a distributed monitoring system with local archiving and remote access to its resources.
Application of media converters and fiber-optic link for video surveillance of a remote industrial plant
The signals from PTZ and fixed cameras are recorded locally on DVRs located in office buildings. The M78516 DVRs belong to the "960H" category (recording resolution 960 x 576 pixels) ensuring increased image quality of the video footage from 650 TVL (700 TVL B/W) cameras. The access to live video and the recordings is possible using client software installed on a computer placed in one of the buildings (the DVRs create an Ethernet network controlled by the N29935 gigabit switch). The Ethernet signal is converted to optical form by the M203G L11025 Ultimode media converter and transmitted via single-mode optical cable UNI-4SM L7644 to the monitoring center, equipped with identical media converter. The use of fiber-optic link ensures insensitivity to interference and lightning.
How to increase the resolution of the recorded video in analog monitoring systems?
In order to maintain efficient operation of CCTV systems it may be necessary to modernize them by replacing DVRs and cameras. When they were installed several years ago, the newer solutions provide better picture quality and more cost-effective method of archiving. Upgrading the existing system or building a new one it is recommended to invest in a new generation of DVRs, such as SIGNAL DL-8508 M78508 and DL-8516 M78516.
Thanks to the WD1 (960x576px) resolution, the M78508 and M78516 DVRs ensure increased image quality of the video footage from 650 TVL (700 TVL B/W) cameras (compared with D1/4CIF DVRs). It is connected with the number of effective pixels in such cameras, 976x582. Common D1(4CIF) DVRs with recording resolution of 704x576 cannot save the full detail provided by the cameras. The examples of such cameras are M11194, M11284, M10775.

Several HDMI devices and one HDMI input in TV/monitor.
HDMI switcher allows the user to connect multiple high-definition devices to a TV equipped with insufficient number of HDMI inputs. There are no problems with simultaneous connection of a satellite receiver, DVD/Blu-ray player, PC or a game console. The amplified signal can be sent via a HDMI 1.3b cable over a distance up to 15 meters. Even when the TV has sufficient number of HDMI inputs, it may be more elegant to connect only one HDMI cable for easy installation on a wall with the use of LCD/plasma mount. It really improves the appearance of the TV suspended on the wall.
