How Do Fiber Optic Connectors Work?

The history of fiber optic telecommunication deserves a book by itself since it took several generations to get the industry today. You can get some good readings here: http://wiki.fiberoptics4sale.com/FiberOpticsHistory

Optical fiber is a long thin cylindrical fiber made from glass or plastic, as tiny as one tenth of a human hair. A standard telecom optical fiber is composed of three cylindrical layers, counted inside out: fiber core (diameter 8~10um), cladding (diameter 125um) and buffer coating (diameter 900um).

Fiber core and cladding is made from glass or silica. Fiber Core and cladding layers work together to confine the light inside the core without leaking. Fiber buffer coating is made from acrylic or plastic and provides handling flexibility and physical protection for the fiber.

Optical fibers utilize an optical phenomenon called total internal reflection. When light is injected into the fiber from end face, it is confined inside the core without leaking outside and losing its energy.

Then light is digitally modulated to represent 1 and 0 just like a computer, so information can be carried from one site to another site which may be from San Francisco all the way to New York.

What are fiber optic connectors and how do they work?

Now you know how optical fibers work. So what is a fiber optic connector and what's its function in a fiber optic telecommunication network?

Put it simple, a fiber optic connector's function is just like an electric power plug, it connects light from one section of optical fiber to another section of optical fiber.

Since optical fibers are so tiny, fiber optic connectors have to be made with high precision, at the scale of 0.1um which is one hundredth of a human hair.

Fiber optic connectors align two fibers end to end so precisely that light can travel from one fiber into another without bouncing off the interface and loss its signal.

Besides, fiber optic connectors provide cross connect flexibility for the telecommunication network. So a complicated computer network could be made modular and easy to manage.

Just like any other connectors used in electric industry, electronic industry and computer industry, many different kinds of fiber optic connectors were invented along the development of fiber optic communication industry. Some of them once were very popular in the industry and now have served their purposes and are fading away.

The most popular fiber optic connectors used nowadays are SC, ST, LC, FC, MTRJ, SMA and a few of other less popular ones. Sure you will see new connectors invented with the progress of this industry.

About 7 million of these people were self employed, most of whom worked full time at home. Chances are you may have a home office yourself or you are making plans to organize one.

Creating a useful and comfortable office depends upon understanding your own particular needs and comparing all your options. You don't want to make costly mistakes by buying the wrong furniture and accessories.

The best situation is when you can devote a room to be used solely for your office. If you aren't lucky enough to have an entire room that you can convert into an office you may still be able to establish a permanent location for your office area. Perhaps you can use a corner in the dining or family room for your desk, chair and computer equipment.

Often times people will try to get by using a standard table or an old fashioned desk. These types of furniture are just not designed for use with computers. Modern computer desks include such features as a slide out keyboard tray, a monitor arm and an enclosed CPU holder. The slide out keyboard tray is an invaluable part of a computer desk.

If you buy a computer cart make sure that it has independently adjustable platforms. This is so you will be able to arrange your CPU, peripherals and monitor in a way that is right for you. A good computer cart will also have rubber coated casters that roll smoothly and can be locked in place.

VoIP (Voice Over Internet-Protocol)

Telephone calls through broadband: this is the future of telephony. Voice Over Internet Protocol (VoIP) technology represents a revolution in the way we communicate. Here's an outline of three of the most common ways that VoIP can be used to make cheap phone calls.

You've probably heard about new technology that allows people to use broadband to make cheap phone calls. Perhaps you already make calls or video-calls yourself from your computer. Whatever you know already, it helps to have a clear, basic grasp of how this exciting new generation of telephone services works and how it can be used.

The technical name for making cheap phone calls using broadband is 'Voice Over Internet Protocol'. Some people call it 'Voice Over IP', or even 'VoIP' (say "voyp"). Perhaps you've heard of 'VoIP phones'. VoIP is, basically, the umbrella term for the technology for making telephone calls using the Internet and broadband. It uses audio systems to encode speech in a way that means that it can be transmitted digitally over an Internet Protocol network.

There are many ways of using VoIP technology and a broadband connection to make phone calls. Here are three of the most common.

1. PC to PC
   The first, simplest and typically free way to use VoIP is 'PC to PC'. For this, you'll need to be at your computer, as will the person you're calling. You'll also both need a headset/microphone/speaker. And you'll need either USB VoIP phone, which plugs into your computer's USB socket. If you don't have that, you can install or download a piece of software called a 'softphone'. This allows VoIP calling without dedicated equipment. Though this is undoubtedly the cheapest way to make VoIP calls, the call quality is often not great. And you're tied to your computer.
2. PC to Phone
   The second popular way to use voice over IP is by using your PC or computer to call a normal landline or mobile phone. The advantage of this is that the person you're calling doesn't need to have signed up with the same service, doesn't need all the equipment etc. You, though, will be charged for these 'outage' calls. And you are, as above, tied to your PC.
3. Phone to Phone
   A VoIP provider sends you a VoIP adaptor. You use this to connect your normal digital cordless ('DECT') telephone to the broadband modem / router on your computer. Once you've installed the VoIP provider's software (this converts the analog signal to a digital one), you continue to use your phone exactly as before, using your existing broadband connection to make cheap telephone calls. To call, you pick up your existing digital cordless (DECT) phone and dial as normal. Your computer doesn't even need to be switched on. When their phone rings at the other end, they answer as normal.
   

The beauty of this final method of using voice over IP is that your computer doesn't even have to be switched on for you to use the VoIP technology and broadband to make calls. The person you're calling doesn't have to have signed up to the same VoIP provider. Nor do they need to have broadband, or be at their computer. In fact, they don't even need to have a computer.

So there it is - three of the most common ways in which you can now use VoIP technology to make cheap phone calls.
