Fiber Optic Cable – A Way Out For Faster Transmission Of Signals.

Since time immemorial we have been in awe of the wonders of technology. Innovations in technology impact us in many ways and bring about changes in our lifestyles. It has made our life lightning speed fast and we are completely enamored by the gifts of technology. Internet being one such gift of technology has made itself indispensable to the lives of individual. Nevertheless there is constant effort to better this very gift of technology so that it becomes lightning fast. The only effective way to deliver this type of future in which everything is surfed at break neck speed is with a fiber optic based infrastructure that primarily uses fiber optic cable. Besides offering significant increase in connection speed, fiber optic networks offer a tremendous capacity to keep up with any new technological advances.

Fiber optic cable is a cable composing of different layers. 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. It is used to relay signals at very fast speed. It is generally made of glass that is long lasting and even stronger than copper and more able to retain its transmission properties after physical stress such as weight strain, or even attack by rats and cockatoos. The fiber that is installed in fiber optic cable is different from copper: in good quality coatings, inside ducts, or in the case of newer systems, encased entirely by electrical transmission wires.

Apart from using a fiber optic cable for relay of data we can use a wireless mode of data transfer but the advantage of using an fiber optic cable lies in the fact that there is no loss of data and much more data can be encoded and sent with fiber optics, and the effective bandwidths are always going to be larger. That's not to say that wireless solutions are poor, rather they have a place that complements the offerings of fiber optical systems.

A form of fiber optic cable is HDMI (High-Definition Multimedia Interface) that is a compact audio/video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards, like radio frequency (RF), coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. Coming in a variety of different types they are meant to bring sophistication to the world of technology.


Upgrade The Wiring With HDMI Cables And Feel The Difference

I still remember the day when I first bought my home theater which included speakers, five disc DVD player, and a receiver. I remember with what excitement I opened the box. But all my excitement turned into a shock when I just plugged the wire and I found that the cable was torn apart on a little stretch. No other option left out, instead of searching out for the best HD (high definition) cables available in the market. After many a clicks I came across a name which I can count on- HDMI (High Definition Multimedia Interface). 

HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable, composite video, S-Video, SCART, component video, D-Terminal, and VGA. HDMI connects digital audio/video sources such as set-top boxes, Blu-ray Disc players, personal computers (PCs), video game consoles, and AV receivers to compatible digital audio devices, computer monitors, and digital televisions.

The transition from analog to digital in the video world has been quick and a key enabler of this has been HDMI, High Definition Multimedia Interface. Virtually all HD equipment utilizes HDMI to transport audio/video from the sources to the display. The original rendition of HDMI, HDMI 1.0 was released back in 2002 and has been the de facto standard for HD Video transmission. As the digital revolution has continued, HDMI has also evolved from 1.0, 1.1, 1.2 and mostly recently HDMI 1.3.HDMI data rate of 4.95 Gbps 1.2 supports aggregate whereas HDMI 1.3 has provision for up to 10.2Gbps, the transition will be gradual with the first devices available to achieve 6.75Gbps initially.

HDMI cables are available are designed in variety of ways like Plenum HDMI, Mini HDMI and Micro HDMI and HDMI Fiber Optic Cable. HDMI cables in a variety of lengths and colors. Flat HDMI cables, due to their thinner form and higher flexibility, make in-wall installation easier, and also allow for installation behind molding and under carpet (though under-carpet installs should be avoided in areas of high foot traffic). Because the wires are spread out flat rather than bundled, there is less potential for signal bleed between them. Mini and Micro HDMI cables are used for the latest mobile phones and video camcorders with an HDMI connector. Fiber Optic HDMI cables provide unmatched signal performance and complete transparency over a very wide range of input resolutions with lengths up to 100 meters. HDMI over fiber optic cables enable signal to be carried much further than conventional HDMI cables without boosters. HDMI over fiber optic is ideal for in-wall long wire runs. So, a wide range and scientifically upgraded HDMI cables allow you to choose the best suited to your demand and needs.

Patch Cables Cat5e : Connecting Electrical Components

Patch Cable or Cord is an electrical or optical cable which is used to connect one electronic or optical device to another for signal routing.Patch Cables are available in different colours so that they will be easily distinguish.Due to the advanced technology , patch cords includes different types such as Microphone Cables , XLR Connector , RCA Connector etc..Patch cord must be short as 3inches (or approx 8cm) so that it will be able to connect stacked components or route signals through a patch bay or as long as 6 meter or more for snake cables .

Mostly Patch cable cat5e are made up of coaxial cables, with the signal carried through a shielded core, and the electrical ground or earthed return connection carried through a wire mesh surrounding the core. Each end of the cable is attached to a connector so that the cord may be plugged in. A patch cable connects two network devices. Patch cables are typically CAT5 / CAT5e Ethernet cables linking a computer to a nearby network hub, switch or router .

There are different types of Patch Cords available in the market such as :


  • Single-conductor wires using banana connector
  • Coaxial Cables using BNC connectors
  • Twisted pair Cat5, Cat5e, or Cat6 cables using 8P8C (RJ-45) modular connectors with T568A or T568B   wiring
  • Optical fiber cables.


Initially the Cat5 Cable is widely used.But due to the advancement in technology Category 5 has been superseded by the Category 5e (enhanced) specification .The statndard lenght of Cat5e Copper Cable decided by ANSI/TIA/EIA standard is 100 metre.But if someone needs to transfer data at longer speed , one must use switch , or repeaters , if needed . Cat 5e Patch Cables suitable for your data and networking requirements . Mostly all of the Cat5e Cables are flush moulded and colour coded with strain relief boots and all cables are tested to meet all industry standards.
Patch Cable really helps in connecting the electonic devices such as routers , modems etc..A multipair (usually 4 pair) high performance patch cable that consists of twisted pair conductors, used mainly for data transmission.
Same as Cat5 Cable , its enhanced version ,Patch Cable Cat5e Cable also become an officially part of 568A Standard.Due to the advanced version , one can easily opt Cat5e Cable which has more fetures and qualities than Cat5 Cables.

Fiber Optic Cables- Connecting The World At A Faster Pace

Communication industry has been stormed by the advent of fiber optic cabling. The key advantages that are offered by these cables include greater bandwidth, light in weight, small size and definitely has more flexibility. In addition to it, the core reason behind its popularity is that advanced technology used by these cables.



As a matter of fact, the whole fiber optic technology makes use of optical fibers. These optical fibers are thin, ultra-flexible and transparent and transmit the light between two ends of the fiber quality as compared to copper wire. So, with their superior technology these are more appropriate for smooth communication between far distances. In addition to it, the usage of these cables results in much less loss of signals which means uninterrupted and smooth communication. To tell you the truth, currently more than 80% of far distance data traffic is transmitted by using this smart optical fiber technology. “Total internal reflection through a light source transmitted by a fiber cable” is the main principal on which whole fiber optic communication is based. Mainly, quality plastic material is used for making these cables. However, these can be made from plastic clad silica or glass in accordance with the budget and application for which these cables are being used. Copper wires used electronic signals to transmit signals whereas light pulses are being used in Fiber optics cables to transmit signals.

Other advantages of Fiber optic cables include it is inexpensive and suits properly to extremely thin diameters in the range between 0.8mm to 40mm. Being extremely thin, a number of fibers can be joint together letting many connections to run in the same cable. It provides clearer phone connections as well as TV receptions, as the light signals which are in the same cable do not hamper each other's functioning. This ultimately results into much less loss of signals. These cables can also be called as the safer ones because no electricity passes through these cables and hence there will not be any fire issues.

In comparison with other wires like copper wires, these cables are definitely the superior ones because these are light weighted and small sized. With above mentioned advantages, it’s evident that why fiber optics cables are being used in many telecommunications and computer networks. These cables are regarded as the most trusted and best replacement of copper wires.
