About Fiber Optic Cable

Fiber Optic Cable is a cable that contains glass or plastic strands of fiber inside an insulated tube that carries information in form of light pulses. These strands of fiber are called core, which is in turn is surrounded by a glass tube called cladding. Due to the phenomenon of internal reflection in the glass tube, the data is preserved safely until the end of the tube. Based on the number of fibers present in the cable, the fiber optic cable can be classified into two types-single mode and the multimode cables.

These cables have higher bandwidth; that is the capacity of transmitting huge amount of information over large distances as well. It is heavily used for computer networking, internet, cable television and telephone systems.

What do Fiber Optic Cables do?

These cables send the data in the form of light pulses through the glass or plastic fibers; which are only as thick as human hair, but has the potential to carry terabytes of information over very long distances with very little or no data loss. We know that light travels very fast and hence the information is converted in form of light particles with the help of a laser device that travels down the cable and at the receiving end is again translated into data by the computer.

What are the Advantages of Fiber Optic Cables over Copper Cables?

  • These are 1000 times faster in transmitting the data when compared to the traditional copper cables to 100 times longer in terms of distance. While copper cables are capable of transferring 1.5 mbps data to the distance of 1.5 miles, the fiber optic cables transmit 2.5 GBPS of data across 124 miles.
  • As the fiber optic cable is made of glass, unlike copper cables, is least affected by Electromagnetic Interference (EMI), an interference caused by the electromagnetic induction to the electric circuits.
  • These are by far the safest as they are hardly prone to any kind of damage due to atmospheric conditions like lightning.
  • These are extremely hard to tap as there is absolutely no amount of data leakage.
  • Durability is another factor that put fiber optic cables in the advantageous position as the glass could break but doesn’t wear down in any form of weather conditions, like copper cables where the outdoor conditions can hamper the durability of the copper cables.

What are the uses of Fiber Optic Cables?

The Fiber optic cables can be used in the various fields given its advantages over the copper cabling. Here are a few of the most popularly used areas where the fiber optic cables are slowly occupying the space of the copper cables.

  • Internet
  • Cable Television

Learn More about Inverter & UPS

UPS (Uninterrupted Power Source)

The UPS is connected to the mains supply through an electrical socket. When there is electricity being transferred from the main supply, UPS also feeds off the electrical energy from the mains. It converts the AC into DC equivalent which charges the UPS battery. At the time of electrical failure, the output of the battery goes through sine wave inverter of the UPS. The sine wave inverter converts the DC into AC equivalent which his fed to the electrical appliances.

Inverter

Unlike UPS, an inverter supplies electrical energy directly to the electrical appliances connected through the wires. And, at the same time, the AC is converted into DC equivalent to charging the battery.

In an inverter, the electrcity goes through the battery of the UPS which keeps getting discharged. There is an arrangement of the relay switch and sensors to monitor the supply from the main power sources. When the mains is turned OFF the sensors convey it to the relay which automatically switches ON the inverter.

UPS v/s Inverter :

1.Back-up

The switch from mains to UPS power supply is swift. There is no lag and you won’t have any system crash or lose any data because of the transition form mains to UPS supply. A 3 to 8 milliseconds is what it takes fro UPS to get in operation.

However, in Inverter, there is a lag of few microseconds which might result in electrical appliance being switched off. The lag time for the inverter is about 500 millisecond.

2.AC to DC conversion

UPS draws continuous AC power from the main supply. This AC power is converted into DC to charge the battery. In the case of a power cut, the battery supplies to electrical appliances until it is completely drained.

An Inverter draws AC power from the main supply which is converted into DC equivalent at the same time. This DC equivalent charges the inverter battery simultaneously.

3.Connection

A UPS is directly connected to the electrical appliances. On the other hand, the inverter is connected to the electrical appliances with the help from the main power supply.

 

Great Guide to Purchase Scanners

Scanner can further be dividing into two categories :

  • Portable document scanners
  • Desktop document scanners

Portable document scanner

This type of scanners consist of foldable document scanners, handheld scanner and pen scanner. They are light weight and easy to use. They can select entire page or any selected portion of it. Let’s have a brief look at benefits of scanners

Desktop document scanners

In Desktop scanners category sheet fed scanners and flatbed scanners can be included. These scanners are usually big in size and they look like photocopiers.

Primary functions of documents scanners

The chief function of this scanner is to obtain the reflections of scanned documents or text and save them in images of PDF formats. There are many scanners who come with a build in optical character recognisation software so it lets you easy to convert images into text.

Benefits of scanners

  1. It takes less storage space than paper – scanned document don’t need storage space in office premises as scanned text stored in desktop so additional vacant office space can be used work adding more value to business.
  2. Lesser the chances of loss of document- scanned file always remained stored in your desktop. So there is very less chances of loss of documents.
  3. No risk of damage of spoiling of paper document- paper document has always risk of being damage. As paper can get wet, it can get burn but a scanned file remained in safe in hard disk.
  4. Better information security- when we store our information in digital form we can use restriction or access code so that no one can access your papers without access code.
  5. Enhanced employee productivity- with digital documents it’s easy to search any text. So it’s save employees time and increased their productivity.

Important things to consider before choosing a document scanner

When it’s come to choosing a this type of scanner you should keep the fallowing point in mind.

It should be relevant to task means if your business has high scanning volume than you should opt for a device that scans more pages per minute.

The size and type of file should be considered while choosing a scanner.

Check whether you need a portable scanner or simple scanner.

 

Ruggedized Monitors

Ruggedized Monitors are with no doubt getting famous day by day. The reason behind this is that the industries are expanding and more and more people and organizations are going to places where normal monitors or devices are not comparable with the environment or situations.

The following article will revolve its essense around these device that are Ruggedized monitors. The majority of the specialized Rugged LCD Displays (RD models) are intended for airborne, shipboard, and arrive based applications. The low specular reflectance and high brilliance show output that are fabulous high encompassing contrast.

These ruggedized displays are rack mountable with locking slides and accessible with HD-15 and DVI interfaces. A few models are wall mount, shaft mount or RAM mountable, and many offer console bundle choices. A large portion of the Industrial Displays (RPD models) highlight conservative plan as 17 inch, 1U rackmount LCDs, with small scale consoles and accompany or without KVM switch. Most item designs have been tried to ensure the client with a uninterruptable utilization of that specific gadget.

Rackmount LCD screens are intended to be a space sparing with a compacted metal development which isolated into two distinct styles; direct mount or rack screen drawer with an implicit slide rail that permits the screen to be hauled out from the rack and lifted up. Various manufacturers of the rugged screen plan a full scope of Rugged screens with high brightness displays and durable metal development which introduced into the standard 19-inch wide rack bureau, permit them to work under cruel workplace, are perfect for mechanical computerization control and display applications.

Screens drawer sort accompanies the flip-up configuration included low profile one rack U high drawer and customizable back mounting sections. The flush mount sort screen accompanies a front metal bezel with mounting gaps and substantial obligation fenced in area on the back of units, each and every unit comes OSD (on-screen show) film switch that lets the client can modify the screen so as to show quality stuff. It is a rugged unit particularly intended for business and military applications.

Mountable units with direct integration, then again, have metal rugged lodging and fits into the standard 19-inch rack in the cabinet. Safety glass is mounted on the LCD board to secure against effect and clean on the LCD board, giving more effectiveness and toughness to the item for a more drawn out life expectancy.

Maximized light transmission

Rather than the see through conductive film terminals utilized by many sorts of PCT sensor, Rugged monitors utilize a matrix of to a great degree fine wires installed in the sensor, which are practically undetectable to the bare eye. The transparent conductive movies, for example, indium tin oxide (ITO) can bring about a detectable shading shift and lessen the brightness of the screen general.

The bad part of ruggedized monitors

Each and everything is this world, has some bad part as well, so some drawbacks or defects of these monitors are that In spite of this technology breakthrough, early usage of modern PCT innovation, although the monitors are mechanically durable, still battled with obstruction from other conductive questions in the region of the sensor, including water beads. That is on account of ruggedizing the touch sensor is not just about physical quality.

Rugged PCT utilizes propelled control firmware which can sift through undesirable flags that may somehow or another enlist false touches. For instance, it can sift through a flag delivered by the client’s palm touching the show surface. It is additionally sufficiently brilliant to rebate signals from water beads in nature, or water spilled onto the screen.
