We are never, whether we know it or not, more than a few steps from an innovative and yet cost-effective Torontech solution. General Applications Optical fibers have a wide number of applications. The use and demand for optical fiber has grown tremendously. Optical fibers have widespread applications in Telecommunication sector, ranging from global networks to desktop computers. These involve the transmission of voice, data, or video over distances of less than a meter to hundreds of kilometers, using one of a few standard fiber designs in one of several cable designs. Carriers use optical fiber to carry plain old telephone service across their nationwide networks. Local exchange carriers use fiber to carry this same service between central office switches at local levels, and sometimes as far as the neighborhood or individual home. Optical fiber is also used extensively for transmission of data. Multinational firms need secure, reliable systems to transfer data and financial information between buildings to the desktop terminals or computers and to transfer data around the world. Cable television companies also use optical fiber for delivery of digital video and data services. The high bandwidth provided by optical fiber makes it the perfect choice for transmitting broadband signals, such as high-definition television (HDTV) telecasts. ToronTech offers a wide range of physical testing machines to evaluate mechanical properties of optical fiber cables. 1

3 Optical Fiber Cable An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications Optical fibers are very strong, but the strength is drastically reduced by unavoidable microscopic surface flaws inherent in the manufacturing process. The initial fiber strength, as well as its change with time, must be considered relative to the stress imposed on the fiber during handling, cabling, and installation for a given set of environmental conditions. There are three basic scenarios that can lead to strength degradation and failure by inducing flaw growth: dynamic fatigue, static fatigues, and zero-stress aging.

4 Optical Fiber Cable Temperature Cycling Chamber- TT-OFTCC Series IEC F1 Application The Optical Fiber Cable Temperature Cycling Chamber TT-OFTTCC is designed to apply temperature cycling on optical fiber cables in order to determine the stability behavior of the attenuation of cables submitted to temperature changes. It features large test chamber, precise temperature control as well as low temperature fluctuations. Changes in the attenuation of optical fiber cables which may occur with changing temperatures are generally the result of buckling or tensioning of the fibers resulting from differences between their thermal expansion coefficient and the coefficients of the cable strength and jacketing members. Test conditions for temperature dependent measurements shall simulate the worst conditions. This test can be used either for monitoring cable behavior in the temperature range which may occur during storage, transportation and usage or to check, in a selected temperature range (usually wider than that required for the above-mentioned case), the stability behavior of the attenuation connected to a substantially micro bend-free situation of the fiber within the cable structure. Features Large glass window design, viewing angle in all directions, hollow electric plating film and anti-condensation design, built-in lights to facilitate the test sample state of real-time observation in the course of testing. Heat preservation material used glass fiber cotton of high-intensity PU foam and high density, which can avoid unnecessary energy loss. Large-size LCD display screen, simple operation, easy to edit programs. PID with automatic calculation function, show failure message. Material quality of inner box is SUS304 # mirror-face stainless steel imported, and outer box is steel plate and the paint. Box body is processed shape using CNC machine tool. RS-232 communication interface, matching recorder. With timing contact, and able to cope with dynamic testing and measure test. The system-wide multi-security protection and power-cut memory. Compressor and environmental-friendly refrigerant (R134a, R404a, R23). Frozen system uses units or low-temperature dual-loop system design. Uses more powerful wing-blower air supply cycle, to avoid any dead end, temperature and humidity are evenly distributed in the test region. Wind-road cycle adopted the design of blowing side wind and return wind. Wind pressure and wind speed are in accordance with test standards Heating, cooling, humidification and de-humidification system is totally unaided to improve efficiency, reduces testing cost, increases life expectancy and lower failure rate. 3
