Fiber Optic ( FO )

What Is FIBER OPTIC ( FO ) ?

A technology that uses glass (or plastic) threads (fibers) to transmit data . A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Fiber optics has several advantages over traditional metal communications lines:

• Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data.
• Fiber optic cables are less susceptible than metal cables to interference.
• Fiber optic cables are much thinner and lighter than metal wires.
• Data can be transmitted digitally (the natural form for computer data) rather than analogically.
• The main disadvantage of fiber optics is that the cables are expensive to install. In addition, they are more fragile than wire and are difficult to splice.

Fiber optics is a particularly popular technology for local-area networks . In addition, telephone companies are steadily replacing traditional telephone lines with fiber optic cables. In the future, almost all communications will employ fiber optics.

FIBER OPTIC On Channel-11

Channel-11 using Fiber Optic for backbone connections and repeater connections, because Fiber optics has several advantages over traditional metal communications lines like above. That is make Fiber Optic media it's save to use, easey to monitor and make connection of Channel-11 more reliable. Channel-11 provide fiber optic for customer too.

Wireless

What is Wireless?

When viewed as a method of data transport, wireless technology appears very similar to wired technology. You have a piece of hardware, a method of transmission, and connections on both ends that transform data from human-intelligible to transportable and back. For both wired and wireless technology, the range of transmission is an issue. You can't move your laptop 15 feet from the wall jack when depending on a 10-foot cable. Similarly, you can't go out for a jog and expect your in-home cordless phone to keep a connection five miles away from its receiver.

But if you get either a 20-foot cable or a wireless connector of sufficient power, you can move your laptop 15 feet away from the wall jack; and if you get a cellular phone, you can go jogging five miles away from your house and still take calls (as long as your service provider has a reasonable antenna set up). The methods of connection and ranges of service available vary in wireless technology just as they do in wired technology. Home telephones with a wireless handset have a more limited range than cellular phones; infrared transmissions have a more limited range than radio-wave (including microwave) transmissions. Different types of wireless solutions can communicate ten feet, ten miles, or with a satellite in orbit.

Why Channel-11 using wireless to client?

According to its name, wireless local area network is a link between some unit computers without using cable as a media. In this case, used a micro radio wave through air as a media with the frequency 2,4 GHz. This Frequency is a frequency ISM (Industrial, Medical & Science) where Indonesia and most state in world have ratified the agreement agreeing using of above mentioned frequency for the sake of industry, health, and science. The existence of the international agreement minimizes the problem of interference frequency with the facility of military and or governmental.

Frequency use 2,4 Ghz for the WLAN by empiric have given very good result especially for the tropical zone, considering wheatear condition which relative stable and at least magnetic trouble from earth. Optimal reach which can be reached till 25 km, on condition that each antenna transmitter and receiver could 'see' each other (good of line of sight, LOS).
