Wireless Internet has truly changed the way the world goes online. Because of this transformative technology, you can go online and enjoy high-speed Internet access without being tied down to your home. In fact, wireless Internet is so wonderful because of the freedom it gives the individual to surf online away from the desktop, on your laptop or other portable device.

Also referred to as "wifi," wireless Internet is usually accessed on a laptop, cell phone, and other mobile computing device. You can also set up a wireless network between the computers in your house using a special router. People use wifi at home as a way to wirelessly access the Internet from any room in the house. It really is the most convenient way to go online in the modern world.

Wireless Internet providers offer a wide range of services to customers with speeds that compete well with DSL and cable. In the past, before the introduction of wireless Internet and routers, the only way you could connect to the Internet on your laptop was through a very slow, dial-up connection. Luckily, wireless Internet now allows you to go online without having to plug into a phone line.

Connection speeds for wireless broadband vary between 384 Kbps and 2.0 Mbps, which is a whopping 35 times faster than your average dial-up speed. This allows users of mobile devices to carry out online tasks on the go - and you can do more than just email and text message. Plus, it allows you to wirelessly set up a network at home with the use of a router.

Wifi and wireless routers make it possible to download streaming media and large files no matter where you happen to be - this is a convenient option for media junkies who just can't get enough of online media, such as videos. This type of router in particular lets you share files between several computers at home. In the past, you had to create a wired network for this to work - now routers make it possible to network more than one home computer more easily. Wireless routers let you bridge several computers together, even in different rooms.

How it works is that you purchase a wireless Internet connection, and then set up a router to transfer the signal elsewhere, and share the Internet connection.

With a laptop and router it's easy to get connected to a wifi signal and take advantage of wireless broadband - almost every laptop sold now comes with a wireless modem already installed. The same goes for portable handheld devices, which have wifi capabilities built right in. The number of wifi hotspots is also increasing, so you can almost always find access to a broadband connection when you need it.

So where do you find a wifi provider? If you want to find a broadband connection in your local area, that isn't in your home or office, all you have to do is search online for hotspots that provide wireless Internet service. There are various websites that help you locate broadband connections in certain areas, especially as wireless Internet access grows in demand.

A wifi connection doesn't have many requirements. Although different from other connections, providers do provide many of the same features provided by other services. A wireless Internet service usually requires a laptop computer or a computer that is connected to wireless routers. A regular computer may need a Wi-Fi card for the service to work properly.

For wireless Internet access you may also need sniffer software that allows you to search out hotspots around your town.

The history of fiber optic telecommunication deserves a book by itself since it took several generations to get the industry today.

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 whats its function in a fiber optic telecommunication network?

Put it simple, a fiber optic connectors 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.
