To learn more visit: www.zulucable.com http The product video describes our selection of fiber optic Mode Conditioning cables used to connect single mode fiber equipment to existing multimode cable plants. Customers use these cables when they need to connect two pieces of equipment that use singlemode fiber, but the building may only have multimode fiber installed. These cables “condition” the singlemode side for use with singlemode equipment, SFP’s, and or GBIC modules. This allows the data to be transmitted over the multimode cable plant. We custom build these cables in 1-2 days right here in California and offer overnight delivery once the cables have build built and tested.
FIBER WAVE rustles with the wind and glows with the energy of the sun. It is environmental art which needs no energy. One can feel the wind, but cannot see it. It is when we see the movement of something that we become aware of the wind. FIBER WAVE is just such a device for making the invisible wind visible.

Optical Fiber and Copper Cable and The Differences
Article by Vivek Gupta
With the advancement of technology, there have been numerous inventions and discoveries. The latest one has been that of Fiber optic cables, which have gained more prominence in the market than the copper cables. These cables are widely used in offices or residential areas. Read the write up ahead to know the differences between optical fiber and copper cable:
About Copper Cable and Optical Fiber Copper cables transmit information through electrical signals. It has been used as a speaker system wire, telephone wire, computer cable wire etc for over years now. Optical fiber comprises of plastic or glass strands to transmit data or information digitally with the use of light rather than electricity. On the other hand, copper cable encompasses of a single thread of copper. The size of the cable varies depends upon its purpose. Sometimes, the cables are protected with the help of a covering known as braiding. The difference between copper cable and fiber optic lies here as the latter cannot transmit electricity but known for providing high theoretical performance.
Difference between Copper Cable and Optical FiberThe significant difference between copper cable and optical fiber is their different resistance against interface. Copper cable is fairly weak against signal interface that comes from microwave or cell phones. With use of fiber optic cable, you are free from all these problems. Moreover, copper cables are inexpensive and suitable for all your home requirements. Fiber optic cables can transmit information to long distances and more swiftly than the copper cables. Moreover, this cable has less weight and a smaller diameter making it much better than its counterpart.
Furthermore, these fiber optic cables require less power and are inflammable. Copper cables can be electromagnetically tapped whereas optical fibers are not easy to be tapped without interruption in the signal. Optical fiber cables help in multi-channel transmission though the use of a single line. Therefore, this cable finds wide application in wiring of home theatre systems and is too expensive than copper cabling.
But the added benefit of using the fiber optical cables are that they offer higher bandwidth and are easy to be installed than copper cables. Fiber optical cables have the capacity to carry signals such as millions of megabits or terabits per second as compared to copper cables, which can carry 2.5 megabit per second. Also, fiber optic cables offers security and less attenuation rate but requires minimal maintenance. LANs( Local area network) also use fiber optics in the backbone and copper cables for the desktop.

High-definition video and audio fiber-optic transmission is controlled by a transmitter and receiver EIX100R EIX100T composition. Optical fiber transmission device through a standard “single-core multi-mode” optical transmission, signal transmission can be more than 1 km, while the adoption of “single-core single-mode,” optical transmission, signal transmission distance up to several tens of kilometers. EIX100T transmitter with an analog VGA input port and a digital DVI input port, and the local analog VGA output, the VGA output for local monitoring. EIX100R the receiver has an analog VGA output port and a digital DVI output port. Transmitter and receiver LED indicator to show Power supply , Video, and optical signal state. 24bit audio data using quantitative, 96kHz sampling rate, to ensure high-fidelity sound transmission. EIX100TR type VGA (DVI) high-definition video and audio optical fiber transmission system, on the need for high-resolution computer video signals, stereo audio and control signals for ultra long distance transmission, is a highly professional system flexibility. The system is specifically used in security systems, campus environment, audio and video advertising, industrial control and large venue (stadium), so as to meet the remote access from a computer or computer video needs. As the data is transmitted through the fiber, virtually no interference. Transmission principle Meaning the deadline EIX100T transmitter uses advanced signal compound (packaging) technology, the control data, audio data and image data combined into a parallel data the way through and the string converted into the optical transmitter module, converted into optical signals, transmission through the fiber to the distance. EIX100T to simultaneously transfer the control of the maximum 8-bit wide data, two-channel audio data and 2x24bit 24-bit image data and other three categories of data can be transmitted as needed 6x24bit 5.1 channel audio data, can receive analog VGA images Digital DVI input and image input. 3 categories of data can be stable and reliable long-distance transmission, by choosing different power single mode or multimode optical transmitter, receiver module, transmission distance can be located in the 1 km, 2 km, and tens of kilometers. If you choose digital DVI input images, images can be zero-distortion transmission of the best. EIX100R receivers through the optical receiver module, the fiber optical signals into serial data, and converted by the string into the solution after the complex circuit, the signal from the isolated compound 3 categories of data: control data, audio data and image data. Features 1, strong anti-interference ability. As the use of optical fiber transmission, the product has strong anti-jamming capability, can effectively suppress common mode interference from radio frequency transmission channel affected. 2, reliable and convenient. Transmitter and receiver only through a fiber connection, easy to use, no professional knowledge, once installed, long-term stability. In addition, because fiber-optic electrical isolation properties, send and receive the ground potential difference between the two places will not have any impact on the transmitter. 3, anti-lightning, anti-static. Transmitter includes multi-level anti-lightning, anti-static protection circuit. Technical parameters 1, transmitter and receiver are a single +5 V operating voltage. 2, the input image format: 640x480120Hz the following (only analog VGA support) 800x60085Hz the following 1024x76875Hz the following 1280x102460Hz 3, the output image format: 640x480120Hz the following (only analog VGA support) 800x60085Hz the following 1024x76875Hz the following 4, input and output audio format: two-channel stereo 5.1-channel stereo (customizable) 5, up to 8-bit wide control of data transmission,
